Removing wax from carpet is easier than you might think. All you need is an old towel and a clothes iron. Put the towel over the wax and then place the hot clothes iron over the towel. Gently move the iron around the towel as if you were actually ironing. The heat from the clothes iron will melt the wax which will then be absorbed by the towel. Make sure you use a towel that you are willing to discard.
