Burning candles in the house can result in wax dripping onto the carpet, where it quickly dries and gets embedded. Tarbox recommends heating it back up to remove it. Place a white cloth over your iron, then put the iron on top of the wax to warm it up. Finally, scrape off the wax with a butter knife.
“When you are done doing that, lay a paper towel over the surface area and iron on the paper,” Tarbox said. “The wax is melting and binds to the paper, and the wax will be gone after a few more applications.”
Important note: Don’t use the iron this way for more than 30 seconds or you risk burning the carpet. And be sure to use a white cloth and white towels since colored ones can transfer the color onto the carpet when heated up, especially if you have a light-colored carpet.
