How to Get Old Oil Stains Out of Clothes Without Damaging the Fabric

You found an old oil stain on your favorite shirt. It’s been through the wash and dryer, and the oil has set into the fabric. You thought the shirt was ruined, but old oil stains can be removed. It’s harder than removing fresh oil because the oil 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 oil. Here’s how to get old oil stains out of clothes.

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

To get old oil stains out of 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 (Best for Most Old Oil Stains)

Step 1: Apply Dish Soap

Apply Dawn Ultra Dish Soap directly to the old oil 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, as rubbing spreads the oil.

Step 3: Let It Sit for 30 Minutes

For old oil stains, the surfactants need more time to break down the set oil. Don’t rinse too soon.

Step 4: Rinse with Warm Water from the Back

Hold the stained area under warm running water from the back of the fabric.

Step 5: Check the Stain

If the stain is gone, wash as usual. If it 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 (For Stubborn Old Oil)

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

Step 1: Spray the Stain

Spray the old oil stain until saturated.

Step 2: Let It Sit for 30 Minutes

For old stains, longer is better. The foam needs time to penetrate the set oil.

Step 3: Wash in Warm Water

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

Step 4: Repeat If Needed

Old oil stains may need 2 to 3 treatments. Repeat the process until the stain is gone.

Method 3: Rubbing Alcohol (For Very Stubborn Old Oil)

Step 1: Apply Rubbing Alcohol

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

Step 2: Let It Sit for 10 Minutes

The alcohol dissolves the set oil.

Step 3: Blot

Blot with a clean cloth. Don’t rub. The oil transfers to the cloth.

Step 4: Apply Dish Soap

Apply dish soap to remove the alcohol and any remaining oil.

Step 5: Wash in Warm Water

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

Method 4: Baking Soda and Vinegar (For Old Oil on Thick Fabrics)

Step 1: Sprinkle Baking Soda

Sprinkle Arm and Hammer Baking Soda on the old oil stain to absorb any remaining oil.

Step 2: Let It Sit for 15 Minutes

Step 3: Brush Off

Brush off the baking soda.

Step 4: Apply Dish Soap

Apply dish soap to the stain and work it in.

Step 5: Pour Vinegar

Pour a small amount of white vinegar over the dish soap. The reaction helps lift the oil.

Step 6: Let It Sit for 15 Minutes

Step 7: Wash in Warm Water

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

What Not to Do

Don’t put old oil-stained clothes in the dryer. Dryer heat sets oil permanently. Always air dry and check first.

Don’t use hot water before treating. Hot water can cook the oil deeper into the fabric. Use warm water after treating with dish soap.

Don’t rub. Rubbing spreads the oil. Press gently.

Don’t use fabric softener. It coats fibers and traps oil.

Don’t give up after one treatment. Old oil stains may need 2 to 3 treatments to fully remove. Repeat the dish soap or Shout method.

Don’t use bar soap. Some bar soaps contain oils that make the stain worse.

Don’t use acetone on synthetics. Acetone dissolves some synthetic fibers.
