Cleaning and Sealing a Mouldy Ceramic Tiled Shower in Galgate

If you have a tiled shower area in your home, it’s very likely you’ve experienced problems with the grout becoming excessively dirty and ridden with displeasing black spots of mould. The underlying issue is due to inadequate ventilation which can be a real problem in modern insulated houses and occasionally the grout can get so imbued with contamination that the problem needs to be resolved professionally.

In the case of this Ceramic tiled shower area, located at a property in Galgate, Lancashire, mould had turned the grout black and had got into the sealant strip around the base. The property owner had tried using the run-of-the-mill cleaning products you can buy in superstores, but they simply couldn’t get the job done. So, she contacted me to see what could be done.

Cleaning Mouldy Ceramic Shower Tiles

At Tile Doctor, we come across the problem of mouldy shower tiles very often. Excess soaps and shampoos – many of which contain chemicals that harmful to the grout – can quickly build-up if not removed, causing mould and soap scum to emerge quickly, and before you know it, you have a problem like this one.

Thankfully, with the right strength product and cleaning methods, mould can be removed quite easily. The cleaning product used here was Tile Doctor Mould Away, which does what it says on the bottle and can quickly remove mould and black spots from grout and silicone. I applied Mould Away to the grout and surrounding Ceramic tiles and left it to dwell for a short period, before starting to clean the affected areas carefully using soft nail brushes and a small amount of water.

Sometimes it is necessary to repeat this process several times to achieve the best possible results, but in this case two attempts was all it took to get the grout looking like new once again.

Following the cleaning, the area was rinsed thoroughly with water, before bring dried off quickly with a heat gun on a low setting. I then sealed the grout with a single coat of Tile Doctor Wall Grout Sealer, which is a water-based sealer designed to protect against water, oil and acid-based contaminants, and stop them from spoiling the appearance of the grout. It also provides a transparent finish that does not diminish the original colouring of the grout. To add the finishing touches, I polished off the Ceramic tiles as these were already fully glazed and did not require any extra sealer.

Cleaning a Ceramic Tiled Shower Cubicle in Silverdale

This ceramic tiled shower cubicle was installed at house in Silverdale, you can see from the photographs below that there was staining from the chemicals in domestic products and there was also a build-up of mould on some parts of the grout and silicone sealant. Mould can get a grip here due to a porous top layer and this is especially a problem in the UK where bathrooms tend to be small with inadequate ventilation.

Cleaning Tile and Grout

The ceramic tiles and grout was treated using Tile Doctor Oxy Pro which is a ready to use tile and grout shower cleaner that comes with a trigger spray attachment which allows the cleaner to mix with air making it lighter and allowing it to stick to vertical surfaces. It was then worked in using a stiff scrubbing brush by hand before being rinsed off with water; this process was repeated a number of times until we had managed to clean all the areas and then left to dry.

Unfortunately it’s not possible to remove mould from silicone sealant, the only solution is to have it stripped off and replaced. Once this was done the edges were cleaned up and fresh mould resistant silicone was applied.

It’s worth mentioning at this point that silicone will last longer if the residue from soaps, shampoos and body washes etc. are rinsed away with clean water after having a shower as it’s the chemical and not the water that damages the silicone in the first place.

Prevention is always better than the cure and another tip you might find useful is to improve ventilation which is a major problem with draught free modern housing fitted with insulation and double glazing, if this is not possible try leaving your shower room door wide open after having a shower. Another option is to look at installing a ventilation and heat recovery system which extracts the hot air from kitchens and bathrooms through a heat exchanger to warm up fresh air from outside and recycles it back into the house.
