We were recently received a referral from a well-known house cleaning company who needed some assistance to resolve an issue with a Marble Tiled Shower at a Georgian property in Ringmer. Unfortunately one of their staff had sprayed a Cillit Bang cleaning fluid onto the tiles to remove Limescale deposits and had marked the tiles with white streaks which could not be removed. Now Cilit Bang is a very strong product and although it has a reputation for tackling tricky cleaning problems it contains Benzenesulfonic Acid which like any acid should not be used on Stone as it will damage it. If you check the internet you will find this problem is not uncommon and numerous people have experienced the same issue, the good news is there is a solution.
Polishing Damaged Marble Shower Tiles
Using a spray bottle containing a dilution of Tile Doctor Pro-Clean and a set of small Diamond encrusted burnishing pads attached to a handheld buffer I went to work on the tiles stripping away the existing sealer and bringing back the surface of the stone. During this process the damage to the tiles started to fade and once the sealer was removed the tiles took on a washed out appearance which was to be expected at this stage.
Sealing Marble Shower Tiles
After drying any wetness with a heat gun I left them for a while so they could be sealed. Assisted by the underfloor heating the tiles soon dried out so after about half an hour I was able to apply a coat of Tile Doctor Ultra Seal which will protect the Marble going forward. During the drying process I took the liberty of cleaning the customers shower unit, not something I’m in the habit of doing but it passed the time.
As you can see from the photographs on this page the white streaky damage caused by the Cillit Bang has now been removed and the surface looks as good as it did before.
This Terracotta Tiled floor was located in a house in the town of Ringmer, East Sussex, it had been a while since it had last been thoroughly cleaned and re-sealed and was now well overdue for some extra attention.
Terracotta Tile Cleaning
To get the tiles clean we applied a strong dilution of Tile Doctor Pro-Clean which is a heavy duty alkaline cleaner/coatings stripper ideal for tiled surfaces. We let the solution dwell on the floor for 10 to 20 minutes before working it into the tiles with a rotary machine fitted with a black scrubbing pad. The photograph below shows the floor half way through this process with the top section cleaned and the bottom section still to do.
The soiled solution was removed from the floor using a wet vacuum and any stubborn areas re-treated before thoroughly rinsing the tiles down with clean water to remove any remaining product and neutralise the floor prior to sealing.
Terracotta Tile Sealing
Once the floor was dry the floor was sealed with TIle Doctor Seal and Go which took some time to do as you need to wait until the first coat dries before applying the second. Terracotta is very porous so seven coats were required to completely seal the floor.
I thing you would agree from the photographs the floor is much improved and the sealer should keep the Terracotta tiles looking good and much easier to keep clean going forward.
