I use Tide on My uniforms , it works great. One very important thing is, when your gi comes home dirty...throw it to wash IMMEDIATLY. Fill the machine(with Cold water, or that Proforce is going to shrink) , throw in the tide and let it sit for a while. You May want to try hot water on those areas, but it does shrink the Gi.. Otherwise...take it to a professional dry cleaner, and see if they have any secret chemicals.
