Washables: Put glycerin (a thick solvent, available at drugstores) on the spot, then rinse with cool water. Apply a combination solvent, such as Shout, and let sit for 15 minutes. Finish with a regular wash cycle.
Nonwashables: Put glycerin on the spot, then rinse with cold water. Treat with a mild detergent, such as Woolite, and very little water. Gently rub to form suds, then rinse with cold water.
