Black Limestone Floor Renovation in Lancaster

Clean and Seal of a Black Limestone Kitchen Floor in Lancaster

This customer from Lancaster contacted us about cleaning and sealing what they thought was a Blue Slate kitchen floor. Having spoke to them over the phone I arranged to pop over and survey the floor to get a better understanding of the work that needed to be done. Lancaster is a few miles South of our base in Carnforth and I’m always passing though.

Having visited the property I was able to confirm that the floor wasn’t Slate but Black Limestone which is notoriously high maintenance due to its acid sensitivity. I mentioned this and they were quite surprised as it had only been laid a few years earlier and it was sold as Black Slate. The two materials do look identical, but if you drop a small amount of something acidic on Black Limestone the stone fizzes and turns Grey and White.

The big problem with Black Limestone is unlike Slate its very porous, this is why you see Slate being used for roof tiling and is still popular covering even to this day. Also, its very acid sensitive, so even Tea, Coffee, Juice, or Wine can mark it, so although popular in gardens it’s certainly not a stone we would recommend for use in a kitchen or bathroom.
Another problem you have is Black Limestone contains natural oils and it’s the oil that gives it that beautiful black colour. Once the oil is washed out of the stone over time or through the use of acidic cleaning products it leaves the stone looking grey and unattractive. This can be resolved however using an oil-based sealer but it is more expensive than a regular stone sealer.

This stone is still workable though, so it’s not all bad news, with the right treatment it can look as good as the day it was laid (if not better) so I came up with a renovation plan that would do exactly that. They were happy to have the work done so we scheduled a date for the work to start.

Cleaning a Black Slate Floor Tiled Kitchen Floor

We find the best way to renovate floors like this is to use coarse diamond pads that can cut into the stone remove any surface damage, contaminates, old sealers and generally leave the stone very clean.

With this floor I started with a very coarse 50-grit DRB pad which is run several times over each stone using only water to lubricate the process. The process generates a lot of soiling and loose sediment that has to be rinsed off the floor with water and then extracted with a wet vacuum. Once this is done the process is repeated with a 100 and then 200-grit pad which together effectively re-hone the stone and remove any scratches caused by the previous pad. A dilution of Remove and Go was also used with the 200-grit pad to ensure the tiles were clean and any remaining sealer not caught by the pads had been removed.

The last step on the first day was to re-point the stone tiles where needed to remove failed and crumbling mortar. This was then left to set hard overnight so we could continue with the renovation the next day.

On day two we followed up the renovation of the stone by moving onto finer Burnishing pads starting with a 400-grit diamond pad applied in the same way and rinsing and extracting afterwards. This was followed by the application of an 800 and then 1500-grit pad to further refine and improve the stone.

The following day the Black Limestone was sealed with a coat of Tile Doctor X-Tra seal which is the Oil based sealer I mentioned earlier. It brings out the true colour of this stone and the seal leaves a sheen appearance to give a very appealing finish. We find one coat is usually enough for this sealer as it’s a lot thicker that other sealers.

Before leaving I talked through aftercare cleaning with two buckets and the importance of using a pH Neutral cleaning product. We recommend avoiding steam cleaners and not to use cheap bleach or acidic cleaning products which can damage the sealer with repeated use.

Red And Black Victorian Tiled Floor Dorchester Pattern Restoration Lancaster

Dorchester Pattern Victorian Tiled Hallway Floor Restoration in Lancaster

This is a Red and Black Victorian tiled floor laid in a Dorchester pattern at a property in Lancaster. The owner has only just bought the property which dates to the 1890s and this floor had previously been covered in carpet which had started to smell and leave a pungent aroma in the air.

Red And Black Victorian Tiled Floor Dorchester Pattern Before Cleaning Lancaster

Once the carpet had been removed and the Victorian floor allowed to breathe and dry out the smell disappeared. This is the right course of action with old floors which were laid without a damp proof membrane, floors of this age need to breathe and allow moisture to rise through the tile and evaporate at the surface, carpets and underlay prevent this.

The damp issues had resulted in efflorescent salts being deposited on the surface of some of the tiles and this is an important consideration when cleaning the floor. Salts and damp go together, so the more water we use the more salts will come through after the floor has been cleaned. Additionally using an alkaline cleaner such as Tile Doctor Pro Clean or Remove and Go this will further increase the alkalinity of the floor and cause yet more salt issues so a different approach is required.

Cleaning a Victorian Tiled Hallway Floor

Naturally I didn’t want to exacerbate the moisture problems by using liquid products to clean the floor, so I used a low, moisture cleaning technique. This involves applying Tile Doctor Acid Gel as the main cleaning agent and working it in with a 200-grit milling pad fitted to a rotary machine. The gel keeps the moisture level low, and it is a very effective cleaning product and being an acid will neutralise the salts in the floor and keep the pH level at the correct balance. Once done the floor was briefly rinsed with water and all the soils extracted with a wet vacuum.

The floor was left to dry off overnight then I called back the following day to see how it had faired. There were some areas where efflorescent salts had appeared, so I spot treated these areas with more Acid Gel and then scrubbed and rinsed with water using the wet vacuum again to remove as much moisture as possible. You will see on the photos how soft the salt was and I was able to scrape it off without too much difficulty, however if left untreated this salt would harden into a crystalline structure and become more difficult to remove.

To make sure the sealer would cope with the damp floor I applied a thin coat of Tile Doctor X-Tra Seal to several areas before leaving. The decision on which type of sealer to apply was influenced by the damp issues as the moisture needs to be able to evaporate at the surface, so it is important to select a fully breathable sealer.

I called back the following day and the floor was more settled, and the sealer had fully cured, the client gave his thumbs up and we continued sealing the floor with one coat of Tile Doctor X-Tra Seal which is fully breathable.

Once completed the floor was transformed and worked well with other period features in the property. For aftercare cleaning I recommended the use of a Neutral PH cleaning product such as Tile Doctor Neutral Clean.

Black Caithness Slate After Renovation Gressingham

Caithness Black Slate Floor Restored with Milling Pads in Gressingham

1 Comment / Bentham Tile Cleaning, Lancaster Tile Cleaning, Slate Tile Cleaning / Russell Taylor

The photos above detail the restoration of Black Caithness Slate pavers at an old cottage in the village of Gressingham on the outskirts of Lancaster. The building was in the process of being completely overhauled and the floor was next on the long renovation to do list.

Black Caithness Slate Pavers Before Cleaning

Caithness Slate from the northern tip of Scotland and is known for its durability and strength however the years had certainly not been kind to this floor and it was in a very bad state.

To restore the appearance of the slate I recommended milling the floor with a set of very coarse pads that would remove a thin layer of stone off the top of the paving slab to reveal new stone underneath. The pointing was also cracked and loose in places so that would also need chopping out and replacing. After milling the stone would also be smoother and once sealed much easier to maintain going forward.

I estimated the process would take four days to complete. Happy to go ahead with the quote a date was booked for the work to start.

Resurfacing Caithness Black Slate

On the first two days there were two of us involved to get through milling the stone which is hard work. We used a set of milling pads applied to a weighted floor machine to cut through the stones surface using water for lubrication. This generates a lot of stone dust so a lot of rinsing and extracting needs to happen to remove it.

Milling carried on into day two but by the end we had started knocking out the old pointing which had already failed and wasn’t too difficult to remove. It was one big room with a partition at one end, the building itself was built in the 1870s or at least that’s as much information as the client could find as it was bought in an auction.

Black Caithness Slate Pavers During Renovation

Due to its age, it had no water or electricity, so we had to work off generators whilst a rudimentary system supplied the water. This was not the easiest job for us as the generators were proving difficult to work with as the relays would overload and cut off the power; this happened more than a dozen times just in the first day alone, but we like a challenge.

As you will see from the pictures the stone flagstones were transformed. This was not a simple clean and seal job, this is milling back the surface using various diamond grits a heavy weighted buffing machine and patience, and some water. Using a wet system, the milling system won’t leave a house full of dust and the diamond grinding leaves the stone much smoother and a lot cleaner which makes it a lot easier to clean and maintain in the future.

Once the milling was complete and the new flexible breathable pointing was applied for which we like to use a product called VDW 800. We then called back the next day and finished the clean, the floor area was left for another day to dry.

Once dry, the floor was then sealing using a single coat of Tile Doctor X-Tra seal which is oil-based sealer that really brings out the colour of the Black slate. Additionally, this sealer is fully breathable so it will cope with the damp conditions you find with old floors that don’t have a damp proof membrane and so won’t peel off after a few weeks.

The client was very happy with the transformation and final finish and invited us back to cover more work in the outbuildings which eventually will join onto the main house. For aftercare cleaning I recommended Tile Doctor Neutral Clean which is an effective tile and grout cleaner that won’t upset the sealer.

Flagstone Floor Restoration Lytham St Annes

Original Flagstone Tiled Floor Restoration in Lytham St Annes

1 Comment / Flagstone Tile Cleaning, Lytham St Annes Tile Cleaning, Sandstone Tile Cleaning / Russell Taylor

The client said when he moved into this house in Lytham St Annes late last year that this room had a really bad smell of damp. The Flagstone floor was covered in carpet and he had the impression that the previous owner’s cat had been known to use it as place to pee!

Flagstone Floor Before Restoration Lytham St Annes

The smell was rank and probably bad for your health so he decided to remove the carpet and the thick underlay underneath. Under that there was some old Vinyl flooring which all came out to reveal the original flagstone floor. As you can see from the pictures it was in a poor state covered in red and white paint, bits of bitumen here and there and the pointing had been lost in several areas of the floor. Additionally, all those layers over the stone would have prevented any moisture from naturally evaporating at the surface thereby resulting in damp.

The client had seen what we could do on our website and sent us some pictures of his floor which covered approximately 16m2. I priced for milling the flagstone as a deep clean would not resolve the shaling issues on its own and only a good mill of the stone would do that. Also, it needed all the pointing that was still in place knocking out and new flexible breathable pointing put back in place.

Cleaning and Repairing a Flagstone Tiled Hallway Floor

Milling stone is not a low-cost option, but it is a lot more cost effective than pulling up the whole floor and putting in a modern subfloor. Milling involves using a weighted buffing machine fitted with different grits and grades of coarse Diamond encrusted pads which cut into the surface of the stone to reveal new stone underneath, you then apply finer pads to hone and refine the surface.

In this case I used a set of Tile Doctor Milling Pads applied in sequence starting with 50-grit, 100-grit and then 200-grit. Water is used to lubricate the process and keep the dust down, it’s also important to rinse the stone off after each pad and extract the slurry that is generated with a wet vacuum.

The floor was then cleaned with Tile Doctor Remove and Go allowing the product to soak in for ten minutes to loosen deep seated paint staining. The Tile Doctor Remove and Go was then worked in with another 200-grit pad before another rinse and extract again with the wet vacuum.

Older floors like this were installed before the invention of the damp proof membrane so moisture is always a concern. To counter any issues that might develop later such as Efflorescence the last step in the cleaning process was to give the floor an acid rinse using Tile Doctor Grout Clean-up, this neutralises any latent salts trapped in the subfloor.

Sealing a Flagstone Tiled Hallway Floor

The milling, re-pointing and cleaning work took two days and we returned for a third day to apply a breathable sealer called Tile Doctor X-Tra Seal. This product is fully breathable and a great choice for any floors where damp can be a problem as it will allow for moisture to rise through the stone and evaporate at the surface. Being oil-based it also adds character to natural stone and adds an appealing low satin finish.

Flagstone Floor After Restoration Lytham St Annes

The whole process completely transformed the appearance of the flagstone floor and really suits the property which was a late Victorian four-story house with a basement. Original features like this are very sought after so it makes sense to restore them as it will add value.

An additional advantage of the milling process is it also reduces the roughness of the stone surface makes it smoother and easier to clean. On the topic of cleaning its worth mentioning that you should never use a strong bleach-based tile cleaning product on a sealed floor as it will erode the sealer prematurely. For a floor like this you need to use a product like Tile Doctor Neutral Cleaner which is a mild but effective cleaning product designed for use on sealed tile and stone.

Indian Sandstone Kitchen Floor Renovation Garstang

Rough Indian Sandstone Floor Milled and Restored in Garstang

1 Comment / Garstang Tile Cleaning, Grout Cleaning, Sandstone Tile Cleaning / Russell Taylor

Due to the textured nature of the Indian Sandstone tiles installed their kitchen, this client from Garstang was having trouble keeping their stone floor clean. Having decided enough was enough they contacted Tile Doctor to see what could be done to rectify the problem.

I went over to survey the floor and could see dirt was being trapped in the riven surface of the Sandstone and any sealer put there to protect the stone had long since worn off. I find the best solution for rough stone floors like these is to mill the stone with coarse diamond pads thereby removing the grubby surface layer and revealing a new surface underneath. This action also flattens the stone to remove the roughness and makes it easier to maintain.

Indian Sandstone Kitchen Floor Before Cleaning Garstang

I provided a price for milling the stone, cleaning up the grout lines and then applying a new sealer to protect it going forward. Happy with the price, the client arranged to purchase the required products, and we booked in a date for the work to commence. It was only a small 5 m2 area so I was happy that it could be done by one Tile Doctor over a couple of days.

Cleaning and Restoring an Indian Sandstone Tiled Kitchen Floor

To mill the Sandstone, we use a couple of very coarse milling pads of different grades which are applied to the stone with water for lubrication. The pads are fitted to a rotary floor machine to which extra weight is added to ensure a good contact with the stone. The floor was rinsed with water as I progressed, and the soiling generated was extracted with a wet vacuum.

Indian Sandstone Kitchen Floor During Cleaning Garstang

Circular pads do struggle to maintain contact with the edges and especially corners so this is done manually using a set of hand-held diamond blocks. I also scrubbed the grout lines with Tile Doctor Pro-Clean to get the lines as clean as possible.

It’s worth noting that Indian Sandstone is full of iron and a lot harder to mill compared to English Sandstone, Flagstone, and Slate etc. As a result, it took most of the first day to complete this stage.

Sealing an Indian Sandstone Tiled Kitchen Floor

Once milled and cleaned I left the sandstone to dry off overnight and then called back the next day to apply the sealer. For this floor we went with Tile Doctor X-Tra Seal which is a breathable oil-based sealer that contains a colour enhancing formula to improve the general appearance of the stone.

What might not be noticeable from the pictures is the smoothness of the stone after it’s been milled, this makes it a lot easier to clean and makes it a lot less absorbent to dirt and muck etc.

The fresh sealer will maintain its appearance for many many years to come and maybe in another 100 years it will need to be milled again.

It always helps to use the right product when cleaning stone after it’s been sealed, so we dropped off a bottle of pH Neutral Cleaner for the client which we call Tile Doctor Neutral Tile Cleaner. This will ensure easy maintenance without damaging the sealer.

Quarry Tiled Floor Renovation Caton Lancaster

Black and Red Dorchester Pattern Quarry Tiled Floor Renovation Caton

1 Comment / Grout Cleaning, Lancaster Tile Cleaning, Quarry Tile Cleaning / Russell Taylor

A first glance you might not notice much improvement in this Quarry tiled floor that we recently worked on at a Victorian house in Caton near Lancaster. However, look closer and you will see that a pattern has been worn into the tiles from a previous covering most likely carpet underlay.

The sealer on the floor was also due to be replaced so having surveyed the floor on my initial visit I worked out a plan to renovate the Quarry tiles which would include deep cleaning the tile and grout, removing the underlay patterning, and then re-sealing the tiles to keep them protected.

Quarry Tiled Floor Before Cleaning Caton Lancaster

Deep Cleaning a Quarry Tiled Floor

To start neat Tile Doctor Oxy-Gel was applied to the floor and left to soak in for twenty minutes giving it time to break down soils etc. Then a 200-grit Diamond burnishing pad was attached to floor buffing machine which was a heavily weighted for extra grip and run a few times over the tiles. These pads are very aggressive and ideal for cleaning off the pattern left by the carpet underlay.

Oxy-Gel was chosen for this as being in Gel form its more manageable and holds itself against the clay Quarry tile for longer allowing the product work to a much harder, whereas a liquid cleaner generally soaks away into the clay and underneath meaning you need to use more water to remove it later resulting in longer drying times.

After the gel has been scrubbed into the tiles (no water needed at this stage) a wet vacuum Is used to remove the soiling generated during the process. After this initial clean a small amount of water is added to the floor and we go over with the same 200-grit diamond pad extracting the water off the tiles within five minutes of it being applied.

With the Oxy-Gel removed the floor was given and acid rinse using Tile Doctor Acid Gel using the same process as before but this time using a Black scrubbing pad and only allowing it to dwell for 10 minutes. Acidic products are quicker acting on clay and so need less dwell time for it to work. Water was then added and after brushing it in to the floor it was removed using the wet vacuum within five minutes. I sometimes do this job twice as this is the last of the deep cleaning process and will ensure the tiles are free from any debris and dirt before we allow the clay tiles to dry out before sealing.

Before finishing for the day, I took time to apply matching grout where it was missing which was mainly around the edges and sponged off the excess. With this done the floor was left to dry off overnight.

Sealing Quarry Tiles

The next day we conducted a damp test, but despite the use of Gel cleaning products it was still too damp to seal. My client however wanted to seal how the tiles would look with the sealer we were planning to use which was Tile Doctor X-Tra Seal, so to do this three tiles were force dried using an Air blower and a Heat Gun.

With the sealer approved the floor was left for two days so it could fully dry out, the damp test showed a much better reading and we were able to crack on applying the sealer to the whole floor. Only one coat of X-Tra Seal was needed, it’s a thick Oil based product that soaks into the pores of the tile protecting it from within, it also fully breathable so ideal for old floors like this one that don’t have a damp proof membrane. Lastly it contains a colour enhancing formula that in this case improved the deep Red and dark Black colours in the tile.

Quarry Tiled Floor After Cleaning Sealing Caton Lancaster

Lastly for aftercare I recommended Tile Doctor Neutral Tile Cleaner which is a gentle but effective tile and grout cleaning product. You have to be careful when choosing an cleaning product for use on sealed tiles as many are bleach based and simply too strong.

Copper Slate Tiled Kitchen Floor Cleaned Sealed in Ribchester

Renovating Copper Slate Tiles with a Semi Riven Finish in Ribchester

1 Comment / Grout Cleaning, Preston Tile Cleaning, Slate Tile Cleaning, Work by Category, Work by Location, Work History / Russell Taylor

This Copper Slate tiled floor at a property in the Ribble Valley village of Ribchester had been sealed just twelve months before by another company who used a topical acrylic sealer as the client wanted a shiny finish. However, this was a bad choice for a semi-riven tile and exacerbated by the fact that the client had three large dogs. The topical sealer just couldn’t cope and the shine on the Slate faded in a few months.

Semi Riven Copper Slate Before Cleaning Ribchester

After discussing the problem, I suggested stripping off what was left of the topical seal and then re sealing with a sturdier impregnating sealer. I recommended a product called Tile Doctor X-Tra seal which is a premium product that improves colour and is very durable so much so it can also be used externally. Since releasing this product last year it has proved to be very popular and has proven to be the answer in numerous tricky situations. It also adds a lustre and patina to the stone. The client was happy to go ahead with my quote.

Cleaning a Semi Riven Copper Slate Tiled Kitchen Floor

My first concern when dealing with a floor situated in a kitchen is to prevent water being absorbed by the kitchen base units and plinths. Normally the plinths can be removed but if not, the solution is to run a bead of silicone around the area of concern. MDF is easily blown by moisture, and it doesn’t take us long to add so it’s well worth doing.

The cleaning started with the application of a strong dilution of Tile Doctor Pro-Clean which was scrubbed into the floor to remove the old sealer. On this occasion it was scrubbed in using a 200-grit milling pad fitted to a rotary machine. As well as stripping off the old sealer this action deep cleans the tile and grout. A lot of soil is released during the process, and this is brushed and rinsed away with clean water and extracted using a wet vacuum.

The next step was to give the floor an Acid Rinse using a product called Tile Doctor Grout Clean-up, this not only cleans the grout but also neutralised the pH of the floor after cleaning with The Tile Doctor Pro-Clean which is an alkaline product.

An acid wash removes grout smears, unwanted mineral deposits and roughens the stone at a microscopic level to provide a better bond for the sealer. You must be careful what you use it on, and we wouldn’t recommend it for use on acid sensitive materials such as Limestone, Marble, or Travertine. Grout Clean-up is however safe to use on Slate, but I wouldn’t leave it on for a long period of time.

After another rinse with water the wet vacuum was deployed again to remove as much moisture from the floor as possible. The floor was then left to dry out fully overnight.

Sealing a Semi Riven Copper Slate Kitchen Floor

The next day after confirming the floor was dry, work started with the application of what would be two coats of Tile Doctor X-Tra seal. X-Tra seal is an impregnating sealer that soaks into the pores of the Slate ensuring dirt cannot reside there.

Semi Riven Copper Slate After Cleaning Ribchester

I would be the first to admit that a topical sealer would have resulted in a shiner finish but clearly this was not a practical choice when you have 3 big dogs who will run around the floor and tear at the sealer with their claws. Topical sealers as the name suggest sit on the surface and are simply not a very practical option for this situation.

Once completed the Copper colour in the Slate was really enhanced, the grout looked much cleaner and overall, the floor looked great; more importantly the client was very happy with the work we had carried out.

For the cleaning of sealed Slate tiles, I recommend the use of Tile Doctor Neutral Clean which is pH neutral and gentle enough for regularly use. Its also provided in concentrated form so a small amount goes a long way. Many of the floor cleaning products you find in supermarkets are bleach based and far too strong for use on a sealed tile resulting in premature damage to the sealer. I forgot to ask what they had been using to clean the floor previously, but this may also have been a factor in why the previous sealer only lasted a few months.

Riven Green Slate Kitchen Floor Renovation Leyland

Old Riven Green Slate Kitchen Floor Renovated in Leyland

1 Comment / Leyland Tile Cleaning, Slate Tile Cleaning, Work by Category, Work by Location, Work History / Russell Taylor

This is an old Riven Green Slate floor in the kitchen of a property in Leyland that dates to when the house was built around 150 years ago. It was looking very worn indeed and the cement pointing was falling out in several areas. The client requested a site visit so we could provide a quote for the renovation.

Riven Green Slate Before Cleaning in Leyland

On inspection I could see the floor was in desperate need of a deep clean, repairs to the pointing and then sealing to add protection going forward. Having worked on the renovation of similar stone floors I was confident we could improve it significantly and with a new sealer applied it would look totally different. They were happy to go ahead with my quote and we booked in a suitable time to carry out the work.

Cleaning and renovation of a Riven Green Slate Tiled Kitchen Floor

Were happy to take on work of any shape and size and as jobs go this was one of the smaller floors I’ve been asked to work on.

Work began with the application of a coarse 200-grit diamond pad fitted to a weighted rotary floor buffer. The pad was worked into the floor using a strong dilution of Tile Doctor Remove and Go for extra cleaning power and lubrication. The scrubbing action releases a lot of dirt and old sealers etc from the Slate turning the solution black. This was then rinsed off with water and the soil extracted with a wet vacuum.

Old floors like this one don’t have a damp proof membrane installed under the stone and so it’s quite common to see moisture from underneath the floor rising through the stone and depositing minerals including salts on the surface as the moisture evaporates. This problem is commonly known as effloresce and to counter it I like to neutralise the alkaline salts by giving the floor an acid rinse. This involves further cleaning the stone using a dilution of Tile Doctor Grout Clean Up which is scrubbed into the stone and then rinsed off with water and extracted afterwards. Not only does this dissolve any salts is also neutralises the use of alkaline cleaners and etches the stone slightly so you get a better bond with the sealer.

Once the floor cleaning part of the renovation plan was complete attention turned to knocking out the old failing cement that was used to grout the Slate slabs. With the rubble cleared away the stone was repointed using a modern breathable and flexible product that will cope with any moisture rising through the floor. Once dry the floor was then cleaned again removing all the soil with a wet vacuum and left to dry overnight.

Sealing a Riven Slate Tiled Kitchen Floor

Calling back the next day one thin coat of Tile Doctor X-Tra Seal was applied which added a bit of lustre and this will add strong protection to the stone. X-Tra seal is a premium product, but it was the perfect product for this stone and situation as its formulated using an oil-based resin that will bring out the colour of the green slate; it’s also fully breathable and waterproof so it’s a great sealer for use in high traffic internal or external areas.

Riven Green Slate During Sealing in Leyland

Again, it’s not a cheap sealer but for old rough stone floors in an old house without a damp proof membrane it ticks all the right boxes. Once done the floor was complete and it looked so much cleaner and healthier.

Riven Green Slate After Sealing in Leyland

As usual I discussed after care with my client and recommend they use Tile Doctor pH Neutral Cleaner which is a lot milder than the bleach based cleaners you often find on supermarket shelves. These stronger products can damage the seal (not the stone) and within weeks or months of using that type of cleaner the sealer will be compromised. It’s the sealer that stops dirt from becoming ingrained into the pores of the stone so it makes sense to use a cleaning product that will maximise its life.
