Before you try to remove the wax stain, it is suggested that you wait untill it completely dries as it will then be easier to remove. The dried wax forms a collected solid mass that can be conveniently scrapped.
Now, take a dull-edged instrument such as a butter knife and scoop up the wax on the carpet as much hard as you can.
Note: Make sure you do not use a sharp edged instrument like a blade or regular knife, as it will damage the carpet fiber.
In order to remove any stubborn stains, place a piece of dry cloth on the top of the affected area and run heated iron over it. This will make the wax liquefy and stick to the dry cloth, which should then be removed softly.
