If you act carefully, you can remove the wax without scratching or gouging the table.

  1. Soften dried wax with a blow dryer on medium heat….
  2. Blot up the softened wax with a soft, white cloth.
  3. Mix 1/2 cup of white vinegar into 1 cup of water.
  4. Dip the cloth into the vinegar mixture, and wipe away any leftover wax
