Finding a burn mark on your kitchen countertop is frustrating. Whether your countertops are laminate, porcelain or a solid surface such as marble or granite, a burn mark diminishes the appearance of the entire surface. You don't have to replace the entire countertop just because of a burn mark. Use the appropriate products and methods for removing burn marks from your specific type of countertop to avoid damaging the surface during stain removal.
Wipe the affected area with a rag and warm, soapy water. This will remove some of the discolouration from the surface.
Squeeze a liberal coating of plain, white toothpaste onto the burn mark. Let the toothpaste sit on the countertop for 10 minutes.
Scrub the countertop gently with a damp rag to remove the toothpaste and the burn mark. Apply more toothpaste and continue scrubbing until the stain is gone.
Apply a slightly abrasive cleaner such as Comet or Soft Scrub if the mark persists. Apply the cleaner with a dry rag, let it sit for 10 minutes, then scrub the area with a toothbrush. Wipe the area clean with a damp rag.
Clean the countertop with a cleaner for your specific type of surface. Marble, granite and other solid-surface cleaners are sold at most home improvement stores.
