Apply a dime-sized amount of toothpaste to a clean but damp cloth. Use white, nongel toothpaste.
Rub the paste into the white fog mark on the table. Rub in a circular motion until the mark is gone or until it is as light as possible.
Wipe the toothpaste residue off the wooden table.
Soak a piece of superfine steel wool in water and rub it over the white heat mark if you can still see it. Rub in the same direction as the wood grain.
Wipe the wooden table with a damp cloth to rinse it. Dry it immediately with another clean cloth.
