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

You have old grease stains on your clothes. Maybe you didn’t notice the stain until after the clothes went through the dryer. Or maybe you treated it once but it didn’t come out. Old grease stains have set, but they can still be removed. The key is using a combination of products to break down the set-in grease. Here’s how to get old grease stains out of clothes without damage.

Old grease stains on clothes are grease that has bonded with fabric fibers and been set by dryer heat. Grease is not water-soluble, so regular washing alone won’t remove it. Removing old grease stains requires a surfactant (dish soap), an absorbent (baking soda), and a stain remover (OxiClean or Shout) to break down the set-in grease.

To get old grease stains out of clothes, apply baking soda to absorb oil, apply Dawn dish soap and let it sit for 15 minutes, spray with OxiClean or Shout foam, wash in the hottest water safe for the fabric, and check before drying. Don’t use cold water, don’t rub, and don’t put the clothes in the dryer until the stain is gone.

Step-by-Step: Removing Old Grease Stains

Step 1: Apply Baking Soda

Sprinkle Arm and Hammer Baking Soda on the stain. Let it sit for 30 minutes to absorb oil. Brush off.

Step 2: Apply Dish Soap

Apply Dawn Ultra Dish Soap directly to the stain. Work it in gently with your fingers. The surfactants in dish soap break down the grease.

Step 3: Let It Sit for 15 Minutes

Let the dish soap sit on the stain for 15 minutes to break down the set-in grease.

Step 4: Apply Shout Foam (For Stubborn Stains)

Apply Shout Advanced Grease Busting Foam to the stain. Let it sit for 10 minutes. The solvents in Shout foam break down heavy grease.

Step 5: Spray with OxiClean (For Extra Power)

Spray with OxiClean Max Force Spray. Let it sit for 10 minutes. The enzymes in OxiClean break down organic matter.

Step 6: Wash in Hot Water

Wash with Tide Free and Gentle in the hottest water safe for the fabric. Check the care label for the maximum safe temperature.

Step 7: Check Before Drying

Check the stain before putting the clothes in the dryer. If the stain remains, treat again and re-wash. Don’t put the clothes in the dryer until the stain is gone.

Alternative Methods

Method: WD-40 (For Very Stubborn Stains)

Step 1: Apply WD-40. Spray a small amount of WD-40 on the stain. The WD-40 reactivates the grease, making it easier to remove.

Step 2: Let It Sit for 5 Minutes.

Step 3: Apply Dish Soap. Apply Dawn dish soap to break down the WD-40 and the grease.

Step 4: Wash in Hot Water.

Note: Test WD-40 on a hidden area first. Don’t use on delicate fabrics.

Method: Chalk (For Light Stains)

Step 1: Rub white chalk on the stain. The chalk absorbs grease.

Step 2: Let It Sit for 10 Minutes.

Step 3: Brush Off.

Step 4: Apply Dish Soap and Wash.

What Not to Do

Don’t use cold water. Cold water doesn’t dissolve grease. Use the hottest water safe for the fabric.

Don’t rub the stain. Rubbing spreads the grease and damages fibers. Press gently.

Don’t put the clothes in the dryer. Dryer heat sets grease stains permanently. Always air dry and check first.

Don’t use chlorine bleach on colors. Chlorine bleach strips color. Use oxygen bleach instead.

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

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

Don’t use too much dish soap. Excess dish soap can leave its own residue. Use a small amount.
