How To Repair Etched Marble
Etch Mark on Marble Countertop
How do you repair marble once it has been etched or looks like a dull water mark on the marble?
Etched marble is repaired by repolishing or refinishing the damaged surface. How it's done depends on the type of finish and the severity of etching. Marble etching occurs
upon contact with acidic foods and drinks like coffee, soda, wine, alcohol and when harsh products like bleach, vinegar, ammonia and most common brand-name cleaners are used for cleaning marble.
Etching is a corrosive chemical reaction that essentially eats at the marble. Think of it like a burn that removes the finished top layer of marble.
It's very noticeable on a polished surface because it exposes dull raw marble. Of course, it happens just the same on a honed surface but is not as visible since honed marble has a matte finish that is more dull to begin with.

.Severe Etch Marks
Severe etching is rare but can occur if an acidic substance is left to sit on the marble countertop or tile for an extended period. It will continue to eat away the marble.
If the damaged area is noticeably rough to the touch, then it is severe.
The above methods may work in some cases, but usually, a stone restoration professional is needed to repair severe etch marks. Different methods for finishing and polishing marble
are needed depending on the condition and level of finish of the marble.
Severe etching requires a more vigorous and specialized treatment. It's pretty rare though, so most often the DIY methods will do the trick quickly and easily on 95% of etch marks even if you have to apply it a few times.
When etching is severe and rough, you can try the DIY methods, but will likely need a pro. Preventing Etching on Marble
To dispel a common misconception, applying a marble sealer does NOT prevent etching.
Sealers prevent stains but cannot stop physical damage to the stone. Etch marks are physical damage.
Preventing contact with damaging substances and cleaners is the only totally successful method.
Some coatings can help prevent etching
but not completely.
The best advice is to use coasters, trivets, cutting boards, practice good marble cleaning habits
and learn to restore etch marks as part of normal maintenance.
