I started using OxyClean as well... around the neck of my gi has yellowed a bit. I really didn't see a change in the brightness... I think I'll soak the neck longer. BUT... if you have a crest on your gi, be careful of getting it wet with oxyclean. I soaked mine a bit, then bundled in my laundry basket for a few minutes before I threw it in the washer. The red dye in my crest bleed. It came out since it was all wet. So, heads up!
