Set-in grease stains can often be removed, even after the clothing has been washed—but don’t put the item in the dryer until the stain is gone, because heat can make grease much harder to remove.
Best method for set-in grease stains
- Check the care label. For delicate fabrics, wool, silk, or dry-clean-only garments, use a professional cleaner instead.
- Put a piece of cardboard or an old towel behind the stain so grease doesn’t transfer through the fabric.
- Apply liquid dishwashing detergent directly to the dry stain. Choose a grease-cutting detergent.
- Gently work it into the fabric with your fingers or a soft toothbrush. Let it sit for about 10–15 minutes.
- Rinse with the warmest water the garment’s care label permits.
- Wash normally with laundry detergent.
- Air-dry and inspect the stain before using a dryer. If you can still see it, repeat the treatment.
For really stubborn stains
For washable, colorfast clothing, you can try a laundry stain remover designed for grease/oil after the dish-detergent treatment. Test it on an inconspicuous area first.
Avoid these mistakes
- ❌ Don’t use a dryer until you’re sure the stain is gone.
- ❌ Don’t scrub aggressively, which can damage fibers.
- ❌ Don’t mix cleaning products, particularly bleach with ammonia, acids, or other cleaners.
- ❌ Don’t assume baking soda or vinegar will dissolve an old grease stain; a degreasing detergent is generally more useful.
For white cotton, an oxygen-based laundry whitener can sometimes help with the remaining discoloration after the grease has been removed, provided the garment’s care label allows it.
