Placing hot cookware on a kitchen countertop can cause it to become scorched and stained with heat marks. Burn marks and heat stains can mar a countertop's aesthetic appeal, depending on the severity of damage. Scorched stainless steel countertops are extremely unsanitary, as damages to their chromium oxide layer eventually cause them to rust. Promptly repair damaged countertops to preserve their appearance and make them functional again. Remove burn marks and heat stains from laminate and stainless steel kitchen countertops using certain techniques.
Dampen a microfiber cloth with warm water. Wipe the laminate surface with the damp cloth to remove debris and provide a clean surface for the repair.
Squirt 1 tbsp of toothpaste directly onto the heat stain. Spread the toothpaste evenly over the stain using a rubber spatula. Allow the heat stain to absorb the toothpaste for 10 minutes.
Scrub the affected area with a clean toothbrush until the heat stain disappears.
Moisten another clean microfiber cloth with warm water. Wipe the countertop with the moist cloth to wash away the toothpaste. Frequently rinse the cloth with fresh water to prevent reapplying toothpaste to the laminate surface.
Wipe the laminate surface with a terry cloth towel to remove all moisture.
Dampen a microfiber cloth with warm water. Wipe the stainless steel surface with the damp cloth to remove grime and provide a clean surface for the repair. Always wipe parallel to the stainless steel's natural polish lines.

Rub the soaked cloth over the stainless steel in circular motions until the heat stains disappear. Pour club soda directly onto the heat stains if they are difficult to remove.
