Dish Soap Cuts Grease
Greasy spills are some of the most difficult to remove from carpeting, but again, the secret is to use the proper product and technique: Place a few drops of grease cutting dish soap, such as Dawn, into a cup of warm water. Gently mix the solution to dissolve the soap.
Pour the solution into a spray bottle and soak the greasy stain. Then blot it up with a white cloth or paper towels. Depending on the size and age of the stain, you may need to repeat this treatment multiple times.
Heat Hardened Wax
Burning candles in the house can result in wax dripping onto the carpet, where it quickly hardens and becomes embedded in the fibers. It’s recommended that you heat the wax back to a semi-liquid state in order to remove it. Place a white cloth over a warm clothes iron (use the “no steam” setting). Then set the iron on top of the wax until it melts. Scrape off the softened wax with a butter knife.
Hydrogen Peroxide to the Rescue
Few carpet stains are as obvious or unsightly as blood. But suffering a paper cut on your finger and getting a few drops on the carpet doesn’t mean your shag is permanently stained. Hydrogen peroxide will get out blood all day long. First, loosen up dried blood with water mixed with a mild detergent. Then use a butter knife to scrape off as much blood from the fibers as possible.
To remove any residual blood, apply full-strength hydrogen peroxide directly to the stain. The solution will immediately start to foam and fizz when it contacts the blood so don’t be surprised. Wait a few minutes, then blot up the hydrogen peroxide and remaining blood with a white cotton cloth or paper towels.
