Using one part white vinegar to four parts hot water, pour the mixture on a carpet stain. Take several white paper towels folding them over each other and lay them over the area, then press with a hot iron. (You will want to work on small areas at a time -- at least no bigger than your paper towels.) The vinegar and heat will lift the dye out of the carpet and into the paper towel. Your paper towels will turn the color of the dye you are lifting out so you can SEE it working. Keep pouring the cleaner on the areas and change your towels when soiled. Just keep this process up until your paper towels are no longer turning color. This method works for Kool Aid & other impossible to get rid of stains.
