Heat stains can occur on your teak wood if a hot item---such as a coffee cup, pot or a pizza box---is placed directly onto the wood. As the wood warms up from the hot item, it gradually changes colour. The result is a white heat mark that is unsightly and difficult to remove. Fortunately, it is possible to remove the heat stain and restore the look of your teak wood.
Create a thick paste with a non-gel toothpaste and baking soda.
Apply the paste directly to the heat stain.
Rub the paste into the stain gently using a sponge or cloth. Continue rubbing until the paste warms.
Saturate a clean cloth in cool water. Wipe the paste off the teak wood with the cloth.
Repeat the process of rubbing in the paste and wiping it away until the heat stain is gone.
Polish the teak wood as you normally would.
Rub the stained area with a fine 000 grade steel wood. Rub with the wood's grain.
Inspect the wood after each pass. Continue rubbing gently until the stain has disappeared.
Polish and wax the teak wood as you normally would.
Pour a little lemon juice into a bowl.
Add cigarette ashes to the lemon juice. Mix the contents thoroughly.
Saturate the corner of a clean cloth in the mixture.
Rub the heat stain with the cloth. Continue rubbing and reapplying the lemon juice and cigarette mixture until the stain is gone.
Wipe the teak wood clean with a damp cloth. Polish the wood as you normally would.
