Can standard floor cleaners available in the supermarket remove efflorescence?
Avoid using any standard floor cleaner that is not known to remove efflorescence, they may be alkaline pH cleaning agents. Alkaline solution will not neutralize, it will only contribute more salts mineral to the floor. Under normal condition, in general, there is nothing wrong with using a dilute alkaline type of cleaner on most marble and granite surfaces, however the results are unpredictable as some solution may have a chemical reaction with the stones. The stones may change or lose their crystalline color over a period of time.
