Sprinkle Sommières earth on the stain and let it act for about 30 minutes before brushing it off. Repeat until the stain vanishes completely. For older stains, leave it overnight. Alternatively, soak the garment in white vinegar and lukewarm water for an hour, then machine wash.
Grass stains cling stubbornly to synthetics, so reach for a targeted textile stain remover like Starwax Textile Stain Remover for biological stains or Rubigine's Extreme “grass” stain remover. Gently dab from the outside in with a clean cloth, then rinse with clear water.
Leather demands gentle care—skip textile removers. Dip a soft toothbrush in milk and rub lightly, or dab with 90° alcohol or white vinegar using a cotton ball.
