How can you get dry oil off linens?

To remove dry oil from linens, start by scraping off any excess oil with a dull knife or spoon. Then, sprinkle baking soda or cornstarch on the stain to absorb the oil, letting it sit for 15-30 minutes before brushing it off. Next, apply a few drops of dish soap directly to the stain, gently rubbing it in, and wash the linens in the hottest water safe for the fabric. Finally, air dry to ensure the stain is completely gone before using a dryer, as heat can set the stain.
