This one is tricky so be patient and go step by step.
Step #1: Get a spoon and try to scoop up the material first. Lets lift the material out of the carpet “try not to smear it into the carpet fibers”.
Step #2: Apply a non-oily nail polish remover to a clean white cloth and gently rub in one direction. Moisten the cloth again gently rub in a different direction. Do not get the backing of the carpet damp with the nail polish remover.
Step #3: Apply a small quantity of cleaner to the stain. (To make the cleaner solution – mix 1/4 teaspoon of a hand dish washing detergent such as Dawn® or Joy® with a large cup of water) Use a blotting motion to work the cleaner into the affected area. If the stain is being removed continue applying detergent and blotting with a white paper towel until the stain is gone.
Step #4: If the stain is still there, flush with water to remove the cleaner, blot with paper towels and then let this stain rest until the next day. At this point the carpet fiber needs to rest and dry. You have done a great job in preparing for step #5 the next day.
Step #5: The next day, if the stain is still there: You are going to use a very common household product of 3% Hydrogen Peroxide. Moisten the stained area with the Hydrogen Peroxide (using a spray bottle) and let it stand for one hour. Repeat this one hour later if necessary. If any staining remains – Agitate, rough up the area with a paper towel, spray once again and then put a folded paper towel on the stain and a weight like a brick on top of the paper towel and let stand until the next day.
Depending on the color of the nail polish, you may have to repeat Steps 3,4 and 5 again a few days later. Don’t be discouraged, some stains just require a little more effort and patience.
NOTE: Light will cause peroxide to change back to water so no rinsing is necessary.
