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.
Damaged bleach on marble.
Bleaching stains removes most discoloration from unsealed marble.
The damage from bleach stems from an entirely different characteristic.
Citrus and alcohol can dull a marble surface so don t places containers.
Unfortunately most common and popular household cleaners like bleach vinegar ammonia citrus cleaners and hydrogen peroxide are too harsh for use on marble and will cause damage to the finish.
A marble poultice is first applied to the surface of the marble above the stain the liquid part of the poultice will be partially absorbed by the marble and will slowly draw out the stains from the marble pours into the white paste material.
The yellow stain didn t fade a bit.
When marble is damaged by an acid it is called etching.
Bleach is alkaline so it doesn t pose the big risk of acidic cleaners which dissolve sensitive stone including marble.
Only use bleach on light colored marble and do not use the poultice method on sealed marble surfaces.
I started to scrub.
If the hydrogen peroxide was unable to remove the staining diluted bleach may be the only product able to do so.
To protect marble surfaces from stains scratches etches and watermarks always use coasters and trays with felt lining.
This is because these cleaners contain acidic materials or chlorine both of which can permanently damage your marble countertops or marble floors.
Your tiles may end up etched pitted or discolored.
I don t recommend this unless like.
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.
This includes brand name cleaners as well.
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.
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.
Wear old clothing and rubber gloves when working with bleach.
This is a lengthy and slow process so the poultice needs to sit on top of the stain for at least 48 hours.
Calcium carbonate the primary compound in marble can be highly reactive to both acidic and alkaline cleaners.
