How to Get Grass Stains Out of Clothes Without Damaging the Fabric

Your kid came home from playing outside with green streaks on both knees. You tried washing the pants with regular detergent, but the green marks are still there. Grass stains are stubborn because they contain chlorophyll (the green pigment) and plant proteins that bond with fabric fibers. Regular detergent alone often doesn’t break down these compounds. But with the right treatment, grass stains can be removed from most washable fabrics. Here’s how.

Grass stains on clothes are marks caused by chlorophyll and plant proteins that bond with fabric fibers. The chlorophyll creates the green color, while the proteins make the stain stick. Removing grass stains requires breaking down both the pigment and the proteins.

To get grass stains out of clothes, apply liquid detergent or dish soap to the stain, work it in gently, let it sit for 15 minutes, then wash in warm water with an enzyme detergent. For stubborn stains, use oxygen bleach or OxiClean Max Force Spray. Check before drying.

Step-by-Step: Fresh Grass Stains

Step 1: Scrape Off Excess

Use the edge of a butter knife to lift any loose grass or dirt from the surface. Don’t rub, as rubbing pushes the stain deeper.

Step 2: Apply Liquid Detergent

Apply liquid detergent or Dawn Ultra Dish Soap directly to the stain. Work it in gently with your fingers.

Step 3: Let It Sit for 15 Minutes

The enzymes in the detergent need time to break down the plant proteins.

Step 4: Rinse with Cold Water from the Back

Hold the stained area under cold running water from the back of the fabric. This pushes the stain out of the fibers.

Step 5: Wash in Warm Water with Enzyme Detergent

Wash with Tide Free and Gentle in warm water. The warm water helps dissolve the chlorophyll.

Step 6: Check Before Drying

Check the stain before putting the garment in the dryer. If the stain remains, treat again before drying.

For Stubborn or Set-In Grass Stains

If the stain remains after the first treatment, try these stronger options:

Oxygen Bleach

Add 1 scoop of oxygen bleach to the wash cycle. Oxygen bleach breaks down chlorophyll and plant proteins without the harshness of chlorine bleach. Safe for most colored fabrics.

Benefit: Effective on stubborn grass stains. Safe for colors. Drawback: Takes longer to work. Soak for 1 hour before washing for best results.

OxiClean Max Force Spray

OxiClean Max Force Spray contains enzymes that break down grass proteins and pigments.

How to use: Spray the stain until saturated, let it sit for 10 minutes, then wash in warm water with enzyme detergent. Not safe on silk or wool.

Rubbing Alcohol

Rubbing alcohol can help dissolve the chlorophyll in grass stains.

How to use: Soak a cotton ball with rubbing alcohol, dab it onto the stain, and blot. Don’t rub. Repeat until the stain fades. Wash with enzyme detergent.

White Vinegar

White vinegar can help break down grass stains.

How to use: Mix equal parts white vinegar and water. Apply to the stain, let it sit for 15 minutes, then wash with enzyme detergent.

Grass Stains on Different Fabrics

Fabric	Best Treatment	What to Avoid
Cotton	Detergent + oxygen bleach	Hot water before treatment
Polyester	Detergent + OxiClean	Chlorine bleach
Denim	Detergent + OxiClean	Hot water
White cotton	Detergent + chlorine bleach	Hot water before treatment
Silk	Professional cleaning	All home treatments
Wool	Gentle detergent, professional cleaning	Enzyme sprays, chlorine bleach

What Not to Do

Don’t use hot water first. Hot water can set the protein in grass stains. Use cold water to rinse first, then warm water to wash.

Don’t rub. Rubbing spreads the stain and pushes it deeper. Blot or press gently.

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

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

Don’t wait. The longer a grass stain sits, the harder it is to remove. Treat as soon as possible.
