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.
The before and after photos are a testament to how significantly the condition and appearance of the grout was quickly improved and needless to say, the customer was very satisfied with the result.
