The first step is to scrape off as much of the grease or oil as possible with a spoon, being careful not to grind the grease into the fabric. Then, lay some paper towels over the stain and press down gently with an iron. This will help absorb some of the greases. You can also sprinkle an absorbent powder such as baking soda, talcum powder, or cornstarch over the stain to soak it up. Finally, use a detergent specifically designed for removing oil and grease stains from clothes.
