When it comes to a summer well spent, there’s one simple truth: grass stains happen. Sure, you can avoid them, but what’s the fun in that? With a few expert tips and tricks, you can handle any grass stain the season throws your way—and better yet, you can do so with at-home and eco-friendly solutions that are easier on you (and your wallet) and gentler on the planet.

Why Does Grass Stain?

In case you’ve ever wondered, what is it about grass that stains so easily? The short answer is chlorophyll: a naturally occurring pigment found in plants (green hued, of course) that just so happens to love binding with the natural fibers found in cotton and wool. Unlike other common staining agents that stick to the surface of our clothes, grass pigments tend to seep deep into fibers quickly and readily.

How to Pre-Treat a Grass Stain

The Oxi Laundry Booster Method

• Mix a small amount of Blueland Oxi Laundry Booster with water and dab into the grass stain. Let sit for a few minutes.
• Using a soft brush (an old toothbrush, for example) gently work the Oxi Laundry Booster into the fabric to lift the stain.

The Vinegar Method

• In a vessel large enough to soak your piece of clothing, combine one part water with one part vinegar.
• Soak your item in the water-vinegar solution for at least 30 minutes.
• After 30 minutes, gently scrub with a soft brush (an old toothbrush will do).

How to Wash Grass-Stained Clothing

• Be sure to use cold water, as hot water may set the grass stain.
• Drop in Blueland’s enzyme-based Laundry Detergent Tablets to gently and effectively lift any remaining pigment from the grass stain during the wash cycle.
• Hang dry or dry with your dryer on delicate/gentle.
• Enjoy your grass stain-free clothing and get back outside!
