Removing Mould from Shower Cubicles

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.

The results are plain to see and my customer was very satisfied with the work.

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.
