I’ve used this myself many times. It’s such an easy little trick. All you need is an iron, microfiber cloth and water. Soak the cloth in water, heat up your iron. Put the microfiber cloth on top of the wax. Run the hot iron over the wet microfiber cloth and watch the wax stick to the cloth! It even takes the wax color out of your carpet! Usually I’ve had to run the iron over the cloth a couple times but this always works. You don’t have to replace the carpet with this simple trick.
