For the purposes of this blog lets say that there are two types of stone in the world. Acid sensitive stone and non acid sensitive stone. Marble and lime stone are highly acid sensitive. That is to say that when the calcium in the stone is exposed to anything acidic (less than 7 on the pH scale), its appearance will be adversely effected. When selecting a cleaner for your stone this fact is critical. If you choose a cleaner with a high pH (highly alkaline) and you will experience a soapy buildup leaving smears, smudges and an overall dull appearance. Choose a cleaner with a low pH, an acidic cleaner, and it will react with the calcium in the stone, in many cases removing/destroying a polish entirely. The polished finish can always be restored by a professional but why go down that road if all you need to do is select the right cleaner.

Some products not to use on polished stone
On polished marble or limestone, anything with a citrus scent (citric acid is still acid) is out. Lysol and Scrubbing Bubbles are acidic. Even Soft Scrub, though it claims to be mild, is far too abrasive for any polished surface.
