For cotton and polyester: Scrape off any excess with a dull knife. Place garment stain side down on a towel. Apply commercial stain remover specialized for oils, such as Carbona Stain Devil. Lipstick will bleed through onto towel. If stain remains, pre-treat with liquid laundry detergent. Rub in with water until suds form. Rinse thoroughly. Use an eye dropper to apply a half-vinegar, half-water solution. Machine wash according to garment care label.
For washable silk and wool: Same as for cotton and polyester, but air dry and take garment to a dry cleaner if stain remains.
