How to Remove Old Grease Stains from Clothes Without Damaging the Fabric

You found an old grease stain on your favorite shirt. It’s been through the wash and dryer, and the grease has set into the fabric. You thought the shirt was ruined, but old grease stains can be removed. It’s harder than removing fresh grease because the grease has been set by heat and time, but with the right products and patience, it’s possible. The key is using a surfactant that can break down the set grease. Here’s how to remove old grease stains from clothes.

Old grease stains on clothes are grease-based marks that have been set by washing, drying, or time. The grease has bonded permanently with the fabric fibers. Removing old grease stains requires stronger treatments than fresh grease: dish soap with extended soaking, grease-cutting stain removers, or rubbing alcohol. Multiple treatments may be needed.

To remove old grease stains from clothes, apply dish soap directly to the stain, work it in, let it sit for 30 minutes, rinse with warm water, then wash in warm water with an enzyme detergent. For stubborn stains, use Shout Advanced Grease Busting Foam or rubbing alcohol. Don’t put treated clothes in the dryer until the stain is gone.

Method 1: Dish Soap with Extended Soak

Step 1: Apply Dish Soap

Apply Dawn Ultra Dish Soap directly to the old grease stain. Use enough to fully cover the stain.

Step 2: Work It In

Press the dish soap into the stain with your fingers. Don’t rub.

Step 3: Let It Sit for 30 Minutes

For old grease stains, the surfactants need more time to break down the set grease.

Step 4: Rinse with Warm Water from the Back

Step 5: Check and Repeat

If the stain remains, repeat steps 1 to 4.

Step 6: Wash in Warm Water

Wash with Tide Free and Gentle in warm water. Check before drying.

Method 2: Shout Advanced Grease Busting Foam

Shout Advanced Grease Busting Foam is formulated specifically for set-in grease stains.

Step 1: Spray the Stain

Spray until saturated.

Step 2: Let It Sit for 30 Minutes

For old stains, longer is better.

Step 3: Wash in Warm Water

Wash with enzyme detergent in warm water. Check before drying.

Step 4: Repeat If Needed

Old grease stains may need 2 to 3 treatments.

Method 3: Rubbing Alcohol

Step 1: Apply Rubbing Alcohol

Soak a cotton ball with rubbing alcohol. Dab onto the stain.

Step 2: Let It Sit for 10 Minutes

Step 3: Blot

Blot with a clean cloth. Don’t rub.

Step 4: Apply Dish Soap and Wash

Method 4: Baking Soda and Vinegar

Step 1: Sprinkle Baking Soda

Sprinkle Arm and Hammer Baking Soda on the stain.

Step 2: Let It Sit for 15 Minutes

Step 3: Brush Off

Step 4: Apply Dish Soap

Step 5: Pour Vinegar

Pour white vinegar over the dish soap.

Step 6: Let It Sit for 15 Minutes

Step 7: Wash in Warm Water

What Not to Do

Don’t put old grease-stained clothes in the dryer. Dryer heat sets grease permanently.

Don’t use hot water before treating. Hot water can cook grease deeper into the fabric.

Don’t rub. Rubbing spreads the grease.

Don’t give up after one treatment. Old grease may need 2 to 3 treatments.

Don’t use fabric softener. It traps grease.
