Stain Removal Tip for Candle Wax:

Spread brown paper (such as a grocery bag) or a terry cloth towel over the area and iron with the setting on "warm." The wax will be absorbed into the paper or towel. Remove any traces with alcohol or dry cleaning fluid.

REMEMBER! Never use a circular motion to remove a spot as this may destroy the texture in the spot area.
