One of the most easiest and homely method to remove a wax from your rug or carpet is to use an iron. You need to be careful and watchful if you decide to go by this method.
Take a white terry cloth towel and get it damp. Make sure that the cloth is damp and now turn the iron on to the lowest setting. Wait a minute until the iron is hot. Be sure you have water in the iron as well because you may need the steam.
Now place the damp terry cloth towel over the wax and fold the towel so that you are double layered. If the terry towel is thin feel free and fold it again over the wax spot. Place the iron on the terry cloth towel and work in a circular motion. Do not leave the iron in just one spot as you do not want to singe the carpet. After about ten seconds lift the towel and see if any of the wax has come off. If it has, then rotate the towel to an area that is clean.
You may have to repeat this process several times. Depending on your iron you may need to turn the heat up a little. Always start at the lowest setting because you do not want to accidentally singe the carpet. After a few attempts you should be able to remove wax from carpet with easy.
Another alternative method to remove wax could be a hair dryer. Try covering the wax with a cloth or paper as described above, then use a hair dryer to heat up the wax. Or you can use ice to freeze the wax and then pick it out of your carpet.
To remove stains left from coloured wax, try gently dabbing the stain with a rag dampened with rubbing alcohol. If the alcohol doesn't do the trick, then try using dry cleaning solvent.
