Q. I believe I have spill marks of vinegar and also some cleaning solution that stained my marble and limestone floors. I need help in which poultice to use.

 

A. Marble and limestone are calcium-based stones, which means they are sensitive to acids found in vinegar and cleaning solutions. The marks you see are likely acid etch damage, which is different than a stain. You will need a professional stone restoration contractor to come hone away the damage and polish to restore the finish of your floors. To find a vetted stone restoration contractor near you, contact us. If the damage is, in fact, a stain only and not etching, then a poultice of mineral spirits and poultice powder may remove the stains.
