How to Remove a Grass Stain from Jeans Without Damaging the Fabric

Your kid came home with grass stains on their jeans. The green stain seems impossible to remove, but denim is a tough fabric that can handle several stain removal methods. Grass stains are a combination of chlorophyll (green pigment) and plant proteins, which makes them stubborn but not permanent. Here’s how to remove grass stains from jeans without damage.

A grass stain on jeans is a combination stain caused by chlorophyll (green pigment) and plant proteins bonding with denim fibers. Grass stains are stubborn because the chlorophyll acts as a dye and the proteins bond strongly with fabric. Denim is a durable cotton twill fabric that can handle scrubbing and stronger stain removers. Removing grass stains requires breaking down the proteins (enzymes) and lifting the pigment (oxygen bleach).

To remove grass stains from jeans, scrape off excess grass, apply Dawn dish soap and let it sit for 15 minutes, scrub with a toothbrush, spray with OxiClean and let it sit for 15 minutes, wash with Tide Free and Gentle in warm water, and check before drying. Don’t use hot water first, don’t put grass-stained jeans in the dryer, and don’t use chlorine bleach on colored denim.

Step-by-Step: Removing Grass Stains from Jeans

Step 1: Scrape Off Excess Grass

Use a dull edge (butter knife or credit card) to scrape off any loose grass. Don’t rub.

Step 2: Apply Dish Soap

Apply Dawn Ultra Dish Soap to the stain. Work it in gently. The surfactants break down the plant oils. Let it sit for 15 minutes.

Step 3: Scrub with a Toothbrush

Scrub the stain with an old toothbrush. Denim is tough enough to handle firm scrubbing. Work from the outside in to prevent spreading.

Step 4: Rinse with Cold Water

Rinse with cold water to remove the dish soap and loosened grass.

Step 5: Apply OxiClean

Spray with OxiClean Max Force Spray. Let it sit for 15 minutes. The enzymes break down the plant proteins and the oxygen bleach lifts the chlorophyll.

Step 6: Apply Baking Soda Paste

Mix Arm and Hammer Baking Soda with water to make a paste. Apply to the stain, let it sit for 30 minutes, scrub with a toothbrush, rinse.

Step 7: Wash in Warm Water

Wash with Tide Free and Gentle in warm water. Add half a cup of baking soda.

Step 8: Add Vinegar to the Rinse

Add half a cup of white vinegar to the rinse.

Step 9: Check Before Drying

If the stain remains, treat again and re-wash. Don’t put grass-stained jeans in the dryer.

Alternative Methods for Grass Stains on Jeans

Use Rubbing Alcohol

Apply rubbing alcohol to the stain with a cotton ball. Blot. The alcohol breaks down the chlorophyll. Test on a hidden area first.

Use White Vinegar

Apply white vinegar to the stain with a cotton ball. Let it sit for 30 minutes. Scrub with a toothbrush and wash.

Use Hydrogen Peroxide (For Light-Colored Jeans)

Apply 3% hydrogen peroxide to the stain. Let it sit for 10 minutes. Don’t use on dark denim as it can lighten the color.

For Stubborn Grass Stains on Jeans

Use Shout Foam

Apply Shout Advanced Grease Busting Foam. Let it sit for 15 minutes.

Use Amodex

For grass stains that leave a persistent mark, apply Amodex Ink and Stain Remover. Work it in, let it sit for 10 minutes, and wash.

Use Enzyme Detergent Soak

Soak the jeans in warm water with 2 tablespoons of Tide Free and Gentle for 1 to 2 hours. The enzymes break down the plant proteins.

Use Lysol for Disinfecting

Add Lysol Laundry Sanitizer to the rinse for heavily soiled loads.

Clean the Machine Monthly

Use affresh Washing Machine Cleaner monthly.

What Not to Do

Don’t use hot water first. Hot water can set the chlorophyll. Start with cold water, then wash in warm water.

Don’t put grass-stained jeans in the dryer. Dryer heat sets the stain permanently.

Don’t use chlorine bleach on colored denim. Use oxygen bleach.

Don’t rub the stain. Rubbing spreads the grass. Scrub with a toothbrush instead.

Don’t wait too long. Fresh grass stains are much easier to remove.

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