This job required the cleaning of Marble Worktops in twelve toilets at a very nice office in the Abingdon Science Park. The building was occupied by a company called Sophos who you may have heard of and over a period of time the Marble had become stained through the build-up of Limescale from the water supply and the cleaning company servicing the office could not clean it off. I’ve seen a few horror stories of stone surfaces being damaged through the use of acidic Limescale removers so the cleaning company was quite right not to touch it.
Polishing Marble Worktops
To remove the Limescale it would be necessary to hone the Marble using a set of small six inch burnishing pads fitted to a handheld buffing machine. The process involves starting with the coarse 400grit pad with a little water which cuts through the Limescale and then moving on to the 800, 1500 and finishing with 3000 grit to hone the surface and build the polish backup. The water helps lubricate the activity and the surface needs to be rinsed down between each pad.
Sealing Marble Worktops
When the surface was dry I applied two coats of Tile Doctor Colour Grow which is a colour enhancing sealer which impregnates the pores of the stone to protect it, it also enhances the natural colours in the stone.
There were twelve of these to do so as you can imagine it took me a while to get round.
If you are experiencing a similar problem with highly polished Marble do get in touch as we can achieve a mirror finish.

The owner of this swimming pool at a large residence in the suburban village of Oxshott had put the property on the market and naturally wanted the pool area to look its best. The pool was surrounded by Porcelain tiles which are very resilient and generally a good choice for a swimming pool surround, additionally the slate effect tiles in this post had a riven surface which would make them less slippery than the highly polished variety. The chemicals used in swimming pools however are quite strong and I suspect this has contributed to the build-up of Limescale on the surface of the tiles.
Cleaning Porcelain Tiles
The first job was to give the tiles a deep clean and this was done by scrubbing in Tile Doctor Pro-Clean diluted 1 part cleaner to four parts hot water using a black scrubbing pad fitted to a rotary machine. Once scrubbed the soiled cleaning solution was removed using a wet vacuum and the tiles given a thorough rinse. There were a lot of tiles to clean and naturally care has to be taken to avoid getting any cleaning solution in the pool.
After rinsing the tiles were dried with the assistance of an air mover so we could get an idea of what other remedial work would be required and in this case it became clear where the areas with Limescale staining were.
Removing Limescale from Porcelain Tiles
To remove the Limescale each stain was spot treated using Tile Doctor Grout Clean-up which is a strong acid based cleaning product normally used to remove grout smears from tiles but also equally useful at dealing with mineral deposits such as Limescale. You have to be very careful with acids on tiles, especially natural stone so once it had done its job the tiles were thoroughly rinsed and the whole floor rinsed again once we have completed everything.
When we had finished the client couldn’t believe the transformation we have managed to achieve.
