How to remove mold from limestone?
To remove mold from limestone, use a diluted solution of hydrogen peroxide (1/2 cup per gallon of water) or a specialized non-acidic mold remover safe for natural stone. Gently scrub with a soft brush, then rinse thoroughly. Avoid bleach on limestone if possible, as it can be harsh, and never use acidic cleaners which will etch the stone. Ensure good ventilation.
