My daughter spilled cranberry juice on our black marble floor. We wiped it up immediately, but there is still the white stains left behind. Any suggestions?

 

Dear Karol:

You don’t have a stain, You rather have a “stain”.

A stain – a real stain – is always darker than the stained material. If it is lighter, it’s either a mark of corrosion created by an acid (etching), or a caustic mark created by a base (bleaching). There are no known exceptions to this rule. In the case of natural stone, bleaching can’t occur, and therefore they are etch-marks all the time: plain and simple surface damages, like shallow chemical scratches.

You should be able to repair that with a good quality polishing compound for marble designed for homeowner and DIYers, like MB-11.

If not, your only option is a reputable stone restoration professional.

Ciao and good luck,
