Dull Marble Kitchen Counter Mark
by Roberta Dixon
QUESTION:We have a marble counter top. It's 12 inch tiles and we did seal it. I'm not sure what got on it, but it has made a dull mark on one of the tiles. It is polished marble. Is there anything that we can do to fix this??ANSWER:Roberta, what you are describing sounds like "etching," which can occur with marble when contacted by an acidic food, drink or product.Harsh cleaning products (like most of the common household cleaners you buy at the store) can also cause etching. Etching is a form of corrosion. When an acidic substance gets on the marble it eats into the marble essentially destroying or removing the thin surface layer. This is most noticeable on a polished finish because the polish is removed revealing the dull raw marble underneath. It has nothing to do with sealing. Sealing helps prevent staining... something absorbing into the pores of the marble. Etching is a completely different issue. The good news is most etch marks can be easily repaired using SCP: Marble Polishing Paste, which is specially formulated to fix this exact problem. Very easy to use... just rub on the area with a clean cloth and it will restore the color and shine. In the future, be sure to always use coaster, trivets, place mats, etc. to protect your marble from acids and other harsh compounds. Of course, you should use ONLY products safe for cleaning marble.
