Marble tile etched
Q. I recently laid out 30 sq feet of marble tile in an entry way. The tile originally was of a high gloss polished look. After the grouting I had a persistent grout haze that would not go away. The instructions on the grout said to use vinegar and water to remove the haze. After 4 cleanings, the tile is dull, still has some haze, and now has what I believe are etch marks (look like water spots ) on each tile. I need advice on how to remove the etch marks, the haze and properly seal, and maintain this floor. Please help.
A. Vinegar is an acid and has etched the marble. You should never use anything acidic on marble. To remove the etching the marble will need to be repolished. The best thing to use is a marble polishing compound. You can try doing a small spot yourself but it may require the services of a qualified stone restoration company if the etching is too deep.
If you decide the etch is too severe or too difficult for you to remove on your own, don't hesitate to contact a qualified stone restoration contractor. To find a Certified SurpHaces PRO partner, contact us.
