How to Remove Grass Stains
Grass stains are a combination of protein, chlorophyll, and other organic compounds that bind strongly to fabric. They are considered one of the tougher stains because the green pigment acts almost like a dye. Pre-treatment with an enzyme-based product or rubbing alcohol works best.
Affected Materials
Step-by-Step Removal
- 1
Pre-treat with enzyme detergent
Apply an enzyme-based laundry detergent or stain remover directly to the grass stain. Enzymes break down the proteins in the grass.
- 2
Let it soak
Allow the detergent to work for 15 to 30 minutes. For stubborn stains, soak the item in cool water with detergent for up to an hour.
- 3
Scrub gently
Use an old toothbrush to work the detergent into the stain with gentle circular motions.
- 4
Rinse and check
Rinse under cool water and inspect the stain. If green pigment remains, apply rubbing alcohol with a cotton ball and blot.
- 5
Wash as usual
Launder the item on the warmest safe setting. Use oxygen-based bleach for white items if needed.
What Not to Do
- ✗Do not use hot water before treating — heat sets grass stains.
- ✗Do not use chlorine bleach on colored items.
- ✗Do not put in the dryer until the stain is fully removed.
- ✗Do not use ammonia or degreaser — these can set grass stains.
