Bleach On White Marble

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.

Bleach on white marble.

Only use bleach on light colored marble and do not use the poultice method on sealed marble surfaces. We see mold the most in grout or in corners of marble showers. 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. Wear old clothing and rubber gloves when working with bleach.

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

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. It is for this reason that we recommend not using white marble in a shower. Bleach is alkaline so it doesn t pose the big risk of acidic cleaners which dissolve sensitive stone including marble. A lot of times the mold is still there and is a living organism.

Bleaching stains removes most discoloration from unsealed marble. Etching is corrosion that eats away at the marble which will cause dull and light colored or clear spots. The use of bleach is the another great method of removing mold stains from marble. The damage from bleach stems from an entirely different characteristic.

Some professionals also recommend applying a clear protective marble wax but refrain from doing so with white. Work in a well ventilated area. 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. So it s best just not to use it.

I started to scrub. I don t recommend this unless like. Purchase marble polish and apply it according to the manufacturer s instructions. The yellow stain didn t fade a bit.
