Remove Water Stains on Carrara Marble
How do you remove water stains from Carrara marble?
The "water stains" you are seeing on your marble are not from water and they are not stains.
Marble countertops are susceptible to acidic foods and drinks and will etch upon contact leaving the dull and light-colored spots behind.
You can remove / repair these spots on polished
(shiny) marble countertops and floors using ETCH REMOVER / Marble Polishing product
engineered just for this purpose.
Very easy-to-use product and will restore the shine and color almost instantly. A must-have product for marble owners.
So back to the spots... nothing has absorbed into the surface (which is what happens with a true "stain"). Rather the marble itself has been damaged and corroded from the acid. It's like a chemical burn.
It's a known marble maintenance issue and a real nuisance for cleaning marble kitchen countertops since it's impossible to prevent etching in the kitchen. Just too many acidic foods.
Etching also occurs when cleaning marble with the wrong type of products. That's why you should only use products safe for cleaning marble
And just to dispel a common misconception, etching has nothing to do with sealing and a marble sealer will not stop etching.
