For cotton and polyester: If stain is fresh, pour on talcum powder or cornstarch to soak up as much oil as possible. Brush or shake off excess. Place garment stain side down onto a towel. Apply a stain remover designed for grease and oil, such as Carbona Stain Devil, according to package instructions. Machine wash according to garment care label.
For washable silk and wool: Same as cotton and polyester, but take garment to a dry cleaner if stain remains.
