Marble Fireplace Hearth Dull Stain
by Susan
QUESTION:We have a black marble fireplace hearth stain. I am not sure what caused the stained. It looks like something was spilled on it. Once I noticed the spill, I cleaned it off, but it seems to have eaten away at the glossy finish and is now dull. What if anything can I do to repair this? Thanks, SusanANSWER:The "stain" is not actually a stain. Like you surmised... the marble has been corroded and the shiny polished layer destroyed.This is called "etching" and occurs upon contact with acidic foods and drinks (soda, coffee, wine, juice) and harsh cleaning products. Most common household cleaners cannot be used on marble because the same thing will happen. This is a known marble maintenance issue. A too acidic or too alkaline substance will etch the marble leaving a dull and often lighter colored spot that creates a lot of confusion and frustration for homeowners when cleaning marble. Fortunately etching can be fixed using SCP: Marble Polishing Paste, which is made specifically for this purpose and will restore the color and shine on polished marble. Honed marble requires a different procedure, but your is polished, so use the paste and use coasters from now on to avoid contact with acids. Also, use only products products safe for cleaning marble. Good Luck, Ryan P.S.
