How Marble Etches
Marble is a beautiful and functional surface UNTIL it Etches!
Understand that all Marble surfaces are Calcium based stone that can be easily damaged by Acids and High Alkalies.

In her article, Edie talks about the pitfalls of living with marble countertops. What I have found over the years is that people don’t understand a few simple cautions. Common household liquids can cause etch marks on marble surfaces:
- Coffee (drips down coffee mug-etch ring)
- Wine (acid) drips down glass also leaving etch marks & rings
- Cleaning Products: Windex with Ammonia destroys marble
- Cosmetics – many contain harsh ingredients
Removing Etch Marks
For minor etch rings and spots, a commercial polishing compound will help restore factory polish. I have used and recommended HMK P21 Polishing Paste for more than 30 years.
Using a soft cotton cloth, or Microfiber Cloth, apply a dollop on cloth and buff into marble etch mark. You must put some force into the buffing action to create enough friction to smooth out the etch marks. Buff off residue with clean area of cloth. Repeat until you are satisfied with results.
For severe marble etch marks that you can feel a rough texture, these will require more aggressive resurfacing techniques. I will follow up with a detailed post at a later date, but for now, please see this LINK
Impregnating Sealers DO NOT protect agains Acids…they work great to prevent stains, but not Etch Marks. You need a physical barrier to protect acids from damaging marble. After protecting marble (and all natural stone) with a penetrating impregnating sealer, you can use the P21 Polishing Paste (like a coat of wax) to marginally protect against etch marks, but you need to re-apply often to help provide protection.
