Q.  My son spilled apple juice on my new limestone floor and now there are marks. Can this be fixed?

A.  Limestone is extremely sensitive to acids and most likely the dull spots are where the acids in the apple juice have now etched the stone. Limestone is also 4 times more absorbent than marble so even if an impregnating sealer was used after installation, it would only minimize and not prevent etching or staining from happening in the first place. You are most likely in need of a restoration professional to resolve the issue. Contact your professional stone and tile restoration contractor. If you do not have a PRO, contact us.
