Save Your Stone: Removing Deep Stains from Marble.
Got water rings on your antique table? Don't panic.
Stain vs. Etch
Dark Spot? It's a Stain (absorbed liquid).
Dull/Rough Spot? It's Etching (surface damage).
The Poultice Method
For deep stains, mix Baking Soda + Hydrogen Peroxide into a thick paste like cake frosting.
The 24-Hour Wait
Apply the paste to the stain. Cover with plastic wrap. Tape the edges. Wait 24 hours. The paste pulls the stain out as it dries!
Fixing "Water Rings
If the spot is dull, use Marble Polishing Powder. Buff in circles to restore the mirror-like shine
ONE BIG NO-NO
NEVER use vinegar or lemon juice to clean marble. Acids destroy the stone!
