How to Remove Grass Stains from Clothing

If you’ve ever wondered how to remove grass stains from clothing, you’re not alone. My kids love to run, slide, and roll in the grass – and while I wouldn’t dream of stopping them, the result is that grass stains are one of the most common types of stains I deal with. Thomas sliding into home plate is basically a guarantee of a nice green streak down his pants.

You might not be able to prevent grass stains either, but the good news is you can remove them from clothing and other fabrics if you act quickly and use the right methods. I’ve cleaned up countless green knees and pant legs, and I’m here to share tried-and-true tips that work fast.

Why Grass Stains Are So Stubborn

Grass stains are tricky because they’re both protein stains and dye stains in one. Grass contains chlorophyll, which has a strong affinity for natural fibers like cotton, meaning it binds tightly to the fabric. To make matters worse, chlorophyll sets quickly, especially if the stain isn’t treated right away.

If the stain sets, it becomes much harder – sometimes impossible – to remove completely. Grass stains often come with extras like dirt or mud, which can complicate removal. If this happens, tackle the grass stain first since it’s more likely to be permanent.

Before You Begin

• If there’s dirt or mud, let it dry completely, then brush it off before working on the grass stain.
• Always air dry stained garments after cleaning until you’re sure the stain is gone – heat from a dryer will set it permanently.
• If the item is labeled dry clean only or made from delicate fabric like wool, satin, or silk, take it to a professional cleaner.

Method 1: Meat Tenderizer

Meat tenderizer contains enzymes (like bromelain from pineapple and papain from papaya) that break down proteins – perfect for the protein component of grass stains.

1. Rinse the stained area with cool water.
2. Sprinkle unseasoned meat tenderizer (like Adolph’s®) over the damp fabric.
3. Let it sit for 30–60 minutes.
4. Wash in the hottest water safe for the fabric.
5. Air dry and check. Repeat if needed.

Method 2: Enzyme Stain Removers

Enzyme-based cleaners like Wisk® or Zout® are designed to tackle protein stains effectively.

1. Rinse the stain from the back under cold running water.
2. Apply enzyme pretreater directly to the stain.
3. Let it sit for 30–60 minutes (do not let it dry on the fabric).
4. Wash according to the garment’s care label.
5. Air dry and check for any lingering color.

Method 3: Rubbing Alcohol + Laundry Detergent

Rubbing alcohol works as a solvent to dissolve the chlorophyll, while full-strength liquid laundry detergent tackles any remaining residue.

1. Rinse the stain under cold water.
2. Lay the garment stain-side down on a clean, absorbent towel.
3. Dab rubbing alcohol onto the back of the stained area, pushing the green color into the towel beneath.
4. Flip the garment so the stain faces up, then apply a tablespoon of liquid laundry detergent.
5. Let sit for 30–60 minutes.
6. Wash as usual and air dry.
