Squeeze 1 tablespoon of nongel toothpaste into a bowl, and add 1 teaspoon of baking soda to the toothpaste.

Use 0000-grade steel wool to scoop up the mixture. Gently rub the mixture over the white spots using back-and-forth motions. Follow the table’s grain lines.
Continue rubbing the white spots with the mixture until it warms up and the spots disappear.
Moisten another cloth with water, and then tightly wring out the cloth. Wipe the mixture off the wood table.
Use a towel to absorb all the moisture from the table.
Buff the wood with oil, polish or wax, depending on the table’s particular finish. Apply the oil, polish or wax with a fresh cloth according to the product label’s instructions. Hard finishes generally don’t require touchups.
