Poultice Stain Remover

Poultice Stain Remover draws stains out of marble, limestone, terrazzo, and other stone that absorbs liquid, once the stain has soaked in deeper than a cloth can reach. If the mark is darker than the stone, you know what spilled (coffee, oil, wine), and wiping hasn't shifted it, try a poultice.

The poultice soaks the stain back up out of the stone and into the paste. That takes about 48 hours: 24 hours under plastic wrap to keep it moist and working, then 24 hours uncovered while it dries and finishes drawing the stain out. When poulticing seems not to work, it was usually rushed or left uncovered.

One kit treats up to about 2 square feet. That's sized for a typical counter stain, a foyer mark, or a vanity spot, not a whole floor. Large or very old stains may need a second round once the stone is fully dry and the first round has lightened the stain without removing it.

Make sure it's a stain before you start. A stain is colour that soaked in from a spill. An etch is a pale, dull patch where acid damaged the polish, and the stone often still feels smooth. A poultice won't bring the shine back to an etch. That needs the Marble Refinishing Kit for small areas or professional refinishing for large ones.

Rust, deep oil, and old stains can be stubborn because they've bonded with the stone over months. Several rounds, with the stone drying fully in between, often work where one doesn't. If a shadow is still there after two full rounds, have it assessed. It may need refinishing, a replacement tile, or a different stain treatment.
