I posted the following last evening........and after that post I began to have trouble receiving messages. I never did know what happened but would like to try again. If you responded to the original post would you please respond again. Or tell me how I find and download my orginial post and any responses.
My master bathroom is finished with marble tiles. Sometime last year I believed my housekeeper had use some caustic cleaner that took the shine off the tiles and left a dull surface on the floor and the step down into the roman tub/shower, a bench in the shower area, and for about a foot up from the tubfloor along the wall opposite the step into the tub. At the time I assumed she had used Tilex to clean the grout. I had the tiles restored ($450.00) and took all the 'caustic' cleaners and put them in cabinets she would not access to. The only cleaners my housekeeper has had available to her since then were 'Method' products, Softscrub and Windex. Method is a brand name of a environmentally friendly line of household cleaners that clearly states they are safe for granite and marble. And which I have used in the master bathroom for years with great success. Several months have passed and the tiles have been damaged in the exact areas in the exact way they were previously. And I believe by something the housekeeper is using because I noticed it a day after she had last been here. It was not immediately visually noticeable -the damage is more noticeable when I squeegee the area after showering. The squeegee drags on the dull, damaged area where it glides over the shinny, polished, undamaged area. In an effort to determine what was going on I used an extra tile that I had and poured Tilex, chlorine bleach, Windex, Method Bathroom & Tile Cleaner, ammonia full strength onto the extra tile. And I left the agents on the tile far longer than my housekeeper would in the process of normal cleaning - the only agent that did damage was the Tilex (which remember she doesn't have access to) and it didn't leave a dull finish as I have described. It simply left the outline of the 'puddle' of the product that was placed on the tile. Any suggestions as to what is happening here?
