For cotton and polyester: Pre-treat stain with liquid laundry detergent. Let sit for five minutes. Machine wash according to garment care label. If stain persists, place garment stain side down on a towel. Apply a commercial grease-remover, such as Carbona Stain Devil, to the back of stain. Residue will bleed through onto towel. Air dry and machine wash again.
For washable silk and wool: Treat with a gentle liquid laundry detergent, such as Ivory Snow, and let sit for five minutes. Apply a small amount of water and rub gently to form suds. Flush with cool water. If stain persists, apply a small amount of liquid dish soap, such as Dawn. Let sit five minutes and flush with cool water again. If stain is still present, take the garment to a dry cleaner.
