Do any of you guys know how to clean the urethane on proto grippers? I get this is a stupid question but I just got some sig chemas and they're a really dark almost green now. Anything will help. Thanks sorry bout the big image
Just ride them shits it doesn't matter. Wheels get dirty, there are probably ways to clean them but it would more than likely compromise the PU. I would just leave it man, they'll ride just the same. Don't worry about what your scooter looks like.
i rode my wheels on carpet in my dorm and it cleaned them up decently well. i have white wheels and you could definitely notice the difference. not sure if it would help out darker colors or super dirty wheels though, but you could always give it a try.
