Bleach On White Marble

The use of bleach is the another great method of removing mold stains from marble.

Bleach on white 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. 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. Your tiles may end up etched pitted or discolored. If the hydrogen peroxide was unable to remove the staining diluted bleach may be the only product able to do so.

Bleach is alkaline so it doesn t pose the big risk of acidic cleaners which dissolve sensitive stone including marble. I don t recommend this unless like. Purchase marble polish and apply it according to the manufacturer s instructions. I started to scrub.

The damage from bleach stems from an entirely different characteristic. We see mold the most in grout or in corners of marble showers. Etching is corrosion that eats away at the marble which will cause dull and light colored or clear spots. 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.

So it s best just not to use it. The yellow stain didn t fade a bit. First i tried a mild solution of dishwashing soap and water. 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.

Wear old clothing and rubber gloves when working with bleach. Work in a well ventilated area. 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. It is for this reason that we recommend not using white marble in a shower.

Calcium carbonate the primary compound in marble can be highly reactive to both acidic and alkaline cleaners. 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. Some professionals also recommend applying a clear protective marble wax but refrain from doing so with white. 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.
