like someone else said theres a lot of stain pen type products that aren't bleach or are really diluted bleach that will get stains out without destroying everything in it's path. don't bleach them not only will it mess up the colors but the glove will fall apart. unless the bleach is real diluted. how bad is the stain though? I mean does it really matter if your gloves are dirty... I like gettin that first stain on my gear cause then you dont have to worry about keeping it perfect anymore.
