Grass-stains are not just for kids and footballers, it can happen to all of us but luckily they’re highly treatable.
Soak the garment in cold water to soften the stain and make it more receptive to cleaning solutions. Never use hot water for non-fatty stains as it will only set the stain into the fabric.
Pre-treat the stain with a stain remover or a small amount of concentrated detergent to loosen up the stain. For colored garments, make sure to use color safe, non-chlorine/bleach-free stain remover.
Rinse the stained area and if needed, finish up by simply washing the garment as normal*.
