Chlorophyll gives grass its green color, and on fabrics it acts as a dye. Only a handful of liquid laundry detergents we tested do an impressive job removing grass stains, including Tide Plus Ultra Stain Release and Persil ProClean Stain Fighter. In fact, these two detergents came close enough to the cleaning power of our top-rated stain remover, OxiClean MaxForce, that you can use them to pretreat stains and wash your laundry. No matter which detergent you use, follow these steps for best results:
1. Apply a dab of detergent to the stain. Rub it into the fabric with your finger or even a toothbrush, and let sit for at least 5 minutes. Do not rinse.
2. Toss it into the washer. Use the warmest wash temperature the fabric allows (warm water helps lift the stain). You can wash the stained items with other clothes—none of the detergents in our ratings redeposited soils on other fabrics in our tests. Select the normal wash/heavy-soil setting because its longer wash time will allow the detergent to really do its job.
3. Check for stains before you throw it in the dryer. The dryer’s heat will set any remaining stains, making them harder, if not impossible, to remove. If stains remain after washing, repeat the steps above, but allow the pretreat detergent or stain remover to soak in longer, even overnight. Or soak the stained item in a mix of water and oxygenated bleach, like OxiClean, Clorox 2, or Borax, which is chlorine
