I was contacted by the owner of a cleaning company in Milton Keynes, after an end of tenancy clean at a house in Sharnbrook went wrong. Unfortunately a member of their staff had incorrectly applied an acid based cleaning product to the Marble shower tiles which like most natural stone is acid sensitive. The cleaning product had etched the stone causing the damage you can see below. Being a reputable company they were determined to put the situation right and we were asked to step in.
Cleaning and Polishing a Marble Shower Cubicle
The first photos show the extent of the damage which had not only damaged the immediate area but as the cleaning product was in liquid form it had ran down the wall had totally ruined the surface of the tiles in the lower half of the shower.
The first thing I did was to protect the shower tray with towels and then began assembling the equipment needed for this job which consisted of a wet polisher, a variable speed polisher, one set of 6” Tile Doctor burnishing pads from 100 grit to 3,000 grit and one full set of diamond blocks from 80 grit upwards.
I then went about testing how far down the scale I would have to go to get the best results. I found that in most areas the application of a 200 grit burnishing pad was adequate to resurface the tile and remove damage but in some areas I had to go down the scale as low as 80 grit to achieve the desired result.
Although only a small area, no more than 4 m2 this job took most of the day. However, as the whole shower room was tiled in the same tiles it was a much more cost effective to restore the damaged tiles than replace them.
