This is a very good procedure for removing wax from carpet. However, I suggest using heavier paper, such as a paper grocery sack or butcher paper. It will withstand the iron's heat longer and allow more time to heat the wax into the paper. Also, be advised that this will NOT help if dye has transferred into your carpet from the wax. The heat may even make that dye harder to remove. If you have a red candle, for example, a solvent made for textiles is a better option for melting the wax.
