Bleach stain on marble countertop.
A bleach stain on a black granite countertop is unsightly and has more than likely removed the top protective coating over the natural stone.
On white marble the staining.
The area was a dull black as opposed to the rest of the countertop.
Bleach and bleach based cleaners have a high ph and can be very alkaline which isn t safe for cleaning marble.
When it s on a table or countertop daily exposure to ordinary household living may cause it to develop stains.
Mold is a common problem in many bathroom settings.
Marble is durable and has a distinctive classic look.
Many store bought cleaners such as lysol windex and even bleach contain acids that initiate corrosion and leave stains and etching.
Bleach can be used to clean granite but if the corrosive liquid is allowed to sit too long on the material it can eat through the protective layer of sealant.
Mold can stain marble bathroom countertops floors etc.
Marble is made of calcium carbonate which reacts with acidic and alkaline substances like bleach.
I also had a bleach stain on my black granite countertop.
These stains can be the result of a water glass that was left on a marble countertop for too long or from hard water buildup around sinks and showers.
Thank you for any help you can provide.
Marble contains calcium carbonate which causes an adverse reaction when exposed to acids.
