What is a good way to get rid of a grass stain?
assistant
The best way to remove grass stains from fabric is to first pre-treat the area with a laundry detergent or spot remover, then launder the item as usual. If the stain remains, you can try using a mixture of equal parts vinegar and water, or rubbing alcohol and water. You may also want to consider trying an enzyme cleaner designed specifically for removing grass stains.
