Does white marble stain.
A marble stain is when a substance is absorbed into the pores of the marble.
Also to my surprise i found that some of the staining that happened before the countertops were sealed faded significantly.
The marble seems to absorb and diminish stains over time.
There are also some new chemicals that are available which contain ammonium thioglycolate which look promising for removing iron oxidation.
Mold can stain marble bathroom countertops floors etc.
If the stain still remains then replacement is the only solution.
If the stain is removed the entire floor can be treated.

Marble is not very absorbent so it does not stain easily.
I also discovered how to lift up small beginnings of stains with a poultice made of baking soda and water mixed into a paste and left on the countertop overnight.

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.
Marble lends itself to decor in metal and copper silver and steel objects really complement its lines and smoothness.
This is because the pores are closed down in the polishing process.
Some metals however also stain the polished surfaces and allow for oxidation and rust buildup.
If the stain still remains then replacement is the only solution.
Water stains are yet another common stain that occurs on marble.
