Start by blotting the stain with a paper towel to absorb excess oil, then apply a small amount of dish soap directly to the stain and gently rub it in. Let it sit for about 5-10 minutes before washing in the hottest water safe for the fabric. Have you had success with any other stain-removing methods before?
