How to Remove Burn Marks From Granite Countertops

While granite resists heat and does not burn, a hot pan or pot may leave a mark on its surface. Treat burn marks with mild soap and water or a homemade granite-safe poultice.

Clean the Countertop

Sometimes, the burn mark is a superficial sooty or food-based stain that can be cleaned off as soon as the granite cools. Wipe down the countertop with a squirt of mild dish soap on a damp soft cloth or sponge. Rinse the cloth or sponge and wipe the area again; then pat it dry with a soft cloth. If the mark disappears, your work is complete. Otherwise, you may need to make a simple poultice to treat the spot.

Make a Stain Poultice

If the burn mark came from a cigarette, incense or any substance that may have left a bit of a burnt residue embedded in an unsealed area of the granite, use a poultice to lift the stain away.

Step 1

Pour enough flour in the a bowl to completely cover the burned area. Use slightly more than you think you may need.

Step 2

Pour in some hydrogen peroxide, stirring it with a plastic scraper, until the mixture has the consistency of a creamy peanut butter.

Step 3

Spread the paste over the burn mark with the plastic scraper. Spread the paste 1/4 inch or so beyond the discolored area.

Step 4

Cover the paste with plastic wrap; then poke a few holes in the wrap near the paste. Use a toothpick to poke the holes.

Step 5

Tape the edges of the plastic wrap down with painter's tape. Remove the plastic wrap and tape after 24 hours or once the paste dries.

Step 6

Scrape off the paste residue with the plastic scraper; then wipe the area clean with a damp cloth or sponge.

Granite Sealer

If the granite looks dull or seems to absorb every liquid spilled upon it, a sealer helps restore its finish and protect the stone. Spray a granite sealer over a clean granite countertop, allowing it to soak in for 10 minutes or as long as the sealer packaging indicates. Buff the area with a soft white cloth, then allow the sealer to cure for six hours or longer before setting items upon the countertop.
