For cotton and polyester: Place the garment stain side down on a towel. Spray the back of the stain with WD-40. After five minutes, flip over and spray front of stain. Rinse in cold water. Rub liquid dish soap, such as Dawn, into stain and rinse again. If stain persists, apply a commercial stain-remover appropriate for the fabric. Machine wash with ½ cup baking soda along with usual detergent.

For washable silk and wool: Do not attempt to clean at home. Take to a dry cleaner.
