The short answer
Blot, cover the stain in baking soda or cornstarch for 15 minutes to pull out the oil, brush it off, work in a drop of dish soap, then wash in the hottest water the fabric allows. Air dry and check before using the dryer.
Grease is oil, so water alone just spreads it. Absorb first, then break it down with soap.
Step by step
- Blot excess grease with a paper towel — don't rub.
- Cover the stain with baking soda or cornstarch and leave 15 minutes.
- Brush the powder off.
- Rub a drop of dish soap into both sides of the fabric and leave 10 minutes.
- Wash in the hottest water on the care label.
- Air dry. If any mark remains, repeat before machine drying — heat sets grease.
What you need
- Paper towels

Common questions
How do I remove an old grease stain that's been through the dryer?
Soak it in dish soap and warm water overnight, then treat with a pre-wash stain remover and wash hot. It may take two rounds.
Does WD-40 remove grease stains?
It can loosen old set-in grease, but you must follow with dish soap to remove the WD-40 itself.
