Get yourself a cool iron and some clean white construction paper to get wax out of your clothes. Lay the paper over the wax and keep the iron cool to start and then adjust it if needed. The hot wax will suck up into the construction paper, then you can use a stain remover to wash out any remaining color stain.
A clothes iron on low and some paper towels should do the trick. Place the paper towels on the stain and move the iron over the top. Be patient as it may take awhile to get the desired result. Good luck!
