Whether it's a burn from a cigarette or you've left your hair straighteners on the bathroom sink top for too long, ugly burn marks can ruin the look of your bathroom suite. Bathroom sink tops are nearly always made from porcelain, which is known for its durability and resistance to scratches and other marks. Removing a burn mark from a bathroom sink top is a simple task, and you can achieve a satisfactory result with basic tools and household cleaning products.
Fill the sink bowl with warm water and a few drops of mild liquid soap. Add soap until the water clouds and is the same color as the soap.
Dampen a clean cloth with the water and wipe the burned area. This should remove any slight discoloration. Empty the sink bowl of the water and soap.
Mix a baking soda cleaning paste in a bowl. This should consist of one part baking soda to three parts water. Stir with a spoon until you get a pastelike texture.
Spread the cleaning paste over the burned area with your fingers. Massage the mixture into the marked area. Leave the paste for around 5 minutes.
Scrub the cleaning paste off with an old toothbrush. Keep brushing until you remove the burn mark. Add a little more of the cleaning paste to stubborn spots if you need to.
Clean the sink top with a cloth, water and a squirt of soap.
