To remove old grease and oil stains, start by blotting the stain with a clean cloth to absorb as much of the oil as possible. Then, sprinkle baking soda or cornstarch over the stain and let it sit for 15-20 minutes to absorb more of the grease. After that, scrub the area with a mixture of dish soap and warm water, and then rinse with clean water. If the stain persists, you can also try using a grease-fighting laundry detergent or a commercial stain remover. Always remember to check the care label of the fabric and test any cleaning solution on a small, hidden area first. **
