any good solutions for grass stains?

try soaking in oxi-clean..buy it in the laundry dept of your local grocery store. it does wonders on all kinds of stains, both new and old..

Biz, or presumably any comparable color-safe bleach usually works for me.

Check the stain before throwing the clothing in the dryer. If some stain remains, retreat and rewash and you are good to go.

dishwasher soap...like cascade...i remember mom used to use this all the time on my brother's football and baseball uniforms when we were growing up...it works great!

bleach if its white or i think they have colored bleach now.

also if its like black and white they have soaps that are supposed to whiten whites and brighten colors.
