Bleach On White Marble

Calcium carbonate the primary compound in marble can be highly reactive to both acidic and alkaline cleaners.

Bleach on white marble.

I started to scrub. A lot of times the mold is still there and is a living organism. Only use bleach on light colored marble and do not use the poultice method on sealed marble surfaces. If iron is present in the marble tile it will begin to oxidize when exposed to water or other oxidizers such as acids and household bleach.

The yellow stain didn t fade a bit. The bleach works great because it kills the mold and also helps to remove the mold stain that is left behind once the mold is gone. Wear old clothing and rubber gloves when working with bleach. Your tiles may end up etched pitted or discolored.

I don t recommend this unless like. If the hydrogen peroxide was unable to remove the staining diluted bleach may be the only product able to do so. Etching is corrosion that eats away at the marble which will cause dull and light colored or clear spots. We see mold the most in grout or in corners of marble showers.

The use of bleach is the another great method of removing mold stains from marble. The best marble whitening method is to use a combination of a mild cleaning agent mixed with an absorbent material known as whiting finely ground white chalk which can be found in most paint or home improvement stores. So it s best just not to use it. I escalated from diluted simple green to undiluted simple green to a vinegar water solution to a diluted bleach situation to pure uncut bleach on a toothbrush.

Bleach can be used sparingly in certain situations in a very very dilute solution but more often than not people get the mix wrong and etch their marble. Bleaching stains removes most discoloration from unsealed marble. Bleach is alkaline so it doesn t pose the big risk of acidic cleaners which dissolve sensitive stone including marble. Some professionals also recommend applying a clear protective marble wax but refrain from doing so with white.

The damage from bleach stems from an entirely different characteristic. On light colored marble you can dilute one quart of bleach with one gallon of hot water or for a small area a size appropriate 4 1 mixture to remove the stain. In general we recommend against using any of our tilex bathroom cleaners both with and without bleach on marble so i wouldn t advise bleach usage here. First i tried a mild solution of dishwashing soap and water.
