Wax Stain

To remove wax from carpet, first chip off as much of the surface wax as possible, using a butterknife or credit card. Then, place several layers of paper towel over remaining wax, and apply a warm iron to draw wax into the paper towels. Replace the paper towels if they become saturated. You could also try using an acetone-based nail polish remover, or a spot dry-cleaning solution with acetone, but remember to always test in an inconspicuos spot first.
