How to Remove Grass Stain from Clothes

Grass Stains: Chlorophyll, Protein, and Dirt Combined

Grass stains are a combination of chlorophyll (the green pigment), proteins, and dirt that bond together into the fabric fibers when you slide or kneel on grass. The chlorophyll is a natural dye that bonds strongly to fabric, while the protein component makes enzyme cleaners especially effective. The key: never use hot water, and treat before the stain dries and sets.

What You'll Need

• Shout Active Enzyme Laundry Stain Remover Spray
• Carbona Liquid Stain Devils
• Dawn Ultra Dish Soap
• OxiClean White Revive Power Paks (for white fabrics)
• Heinz White Vinegar
• Microfiber cloths
• Soft brush or old toothbrush
• Cold water

Step-by-Step: Removing Grass Stains from Clothes

1. Brush off any loose grass and dirt before treating. Don't rub — brush gently to remove surface debris.
2. Apply white vinegar first. Pour Heinz White Vinegar directly onto the grass stain. The acidity helps break down the chlorophyll pigment. Let sit 10–15 minutes.
3. Apply Shout Enzyme Spray. Spray Shout Active Enzyme Stain Remover generously over the stain. The triple-enzyme formula breaks down the protein component of grass stains. Let sit 15 minutes.
4. Scrub gently with a soft toothbrush to work the enzyme cleaner into the fabric fibers.
5. Apply Carbona Stain Devils for the green chlorophyll pigment. Carbona Liquid Stain Devils targets dye-based stains. Let sit 10–15 minutes.
6. Rinse with cold water and check. Apply a few drops of Dawn dish soap if any residue remains.
7. Machine wash cold. For white fabrics, add an OxiClean White Revive Power Pak. Check before drying — never put in the dryer until the stain is completely gone.

For Dried or Set-In Grass Stains

1. Soak in white vinegar for 30–60 minutes to rehydrate and begin breaking down the chlorophyll.
2. Apply Shout Enzyme Spray generously and let sit 20–30 minutes.
3. Scrub with a toothbrush, then apply Carbona Stain Devils. Let sit 20 minutes.
4. Machine wash cold with OxiClean (white) or regular detergent (colored). Repeat if needed.

Grass Stains on Different Fabrics

• Cotton/denim: Full method works well; most forgiving
• Polyester: Responds well to enzyme cleaner; may need extra Carbona treatment for green pigment
• Wool/delicates: Use enzyme cleaner very gently; hand wash cold
• White fabrics: Add OxiClean White Revive for full stain and pigment removal

Frequently Asked Questions

Why are grass stains so hard to remove?

Grass stains are a combination of chlorophyll (a natural dye), proteins, and dirt that bond together into fabric fibers under pressure — like when you slide or kneel on grass. The chlorophyll dye component is what makes them particularly stubborn. Enzyme cleaners handle the protein, while Carbona Stain Devils and white vinegar tackle the pigment.

Does white vinegar remove grass stains?

Yes — white vinegar is effective at breaking down chlorophyll pigment in grass stains. Use it as a pre-soak before applying enzyme cleaner for best results.

Can grass stains be removed from white clothes?

Yes — use the full method with white vinegar, Shout Enzyme Spray, and Carbona Stain Devils, then wash with OxiClean White Revive. Fresh grass stains on white fabric come out completely with this method.
