Saturate area with pretreatment laundry stain remover (aerosol-types work better on greasy stains). Wait one minute for product to penetrate the stain. For stubborn stains, rub with heavy-duty liquid detergent. Launder immediately.
If color stain remains, soak/wash in chlorine bleach if safe for fabric, or in oxygen bleach.
For extra heavy stains, apply dry cleaning fluid to back of stain over absorbent paper towels. Let dry, rinse. Proceed as above.
