Mr Clean Magic Eraser Marble Countertop Damage
(Panama City Beach)
We installed honed marble...white with grey/beige veining. Our grown kids were visiting...got a water mark on it, and my daughter in law used a Mr Clean magic eraser (extra power) on it. It removed the water mark, but now you can see where it was rubbed. Is this fixable?
I would guess that the Mr. Clean magic eraser chemical composition will damage marble like nearly all common and brand-name household cleaners do.
The "water spot" was caused by something acidic that etched the marble countertop.
I'm betting that the eraser likewise etched or corroded the marble surface leaving a dull and possibly lighter-colored spot rather than a scratch.
You can no longer "see" the "water mark" because the Mr. Clean eraser simply further damaged and etched the original mark and more marble around it creating new borders.
But either way (scratch or etch) you can use the Marble Polish / Etch Remover
to restore the finish quickly and easily on a polished (shiny) marble surface.
This paste is made specifically for this purpose.
If your marble countertop is in the kitchen, then you can expect many more episodes of etching, so the paste is a must-have for polished marble.
However, you stated that you have honed (matte finish) marble. There isn't any product like the paste for a honed surface.
You have to hire a marble maintenance professional or give it a shot yourself (not hard) following the step-by-step instructions in the Removing Etch Marks ebook
Unfortunately, the only way to stop etching is to avoid contact with acids and harsh cleaners, which is the reason most fabricators and installers will warn against installing a marble kitchen countertop.
Well, there are permanent coatings that can be applied, but it's not a good idea... can make your marble look plastic and often cause more problems than they cure.
So, use coasters, trivets, cutting boards, etc. and be sure to use only products safe for cleaning marble
