not just for shoes
I wear a hat at work that gets the expected sweat stains but also nasty grease stains from the equipment I work around. running a cap through the laundry messes with their shape and causes the plastic grid in the forehead to poke through the cloth and scratch my head. I tried this gel shoe cleaner for the hell of it because it was there and it worked great.
next I tried it on a set-in pizza sauce stain on a t-shirt with great success. my girlfriend used it to get out a big food oil stain on her son's t-shirt.
I'm gonna keep trying it on different stains. has anyone else tried this?
