Cranberry juice on black marble...

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,
