If you're renting an apartment and it needs to look the same upon move-out as it did when you moved in, you may want to repair any burn marks that have ended up on your kitchen counter. Unsightly burn marks can happen quickly if you leave a hot pot or pan on your counter. A few home remedies to remove the burn marks may work without damaging the countertop.
Erase burn marks from a laminate countertop with white toothpaste. Squeeze plain old white toothpaste on to the burnt area and rub it in with a toothbrush until the burn mark is gone. Wipe the toothpaste away with a lint-free cloth that you've dampened with water. Repeat if necessary.
Create a paste out of baking soda and water to repair burn marks on a porcelain countertop. Combine equal amounts of both, and rub the mixture on to the burn and scrub it gently with the toothbrush. Allow the baking soda to sit on the burn marks for at least 10 minutes, if not longer. Rinse away the excess baking soda up with the damp, lint-free cloth.
Sand burn marks away on a solid surface or laminate countertop. This should be a last option because sandpaper may hurt your countertop. Gently rub sandpaper over the burn marks until they have disappeared. If you are scared to use sandpaper, try a nylon sponge that is slightly abrasive or a foam eraser sponge. Try a nylon sponge on stainless steel countertops but be very gentle when rubbing burn marks away.
