I only have to use about an ounce per load, which is a good thing because it's expensive, and it leaves my stinky workout clothes smelling fresh, almost like new, but not quite.
I use WIN for all of my nasty workout clothes, especially the dri-fit stuff. I have tried several different sport washes to get the musty smell out of my clothes and none have worked until WIN. Its the only thing i've found that makes my clothes smell clean, even after I'm wearing them again during a workout. Its so nice to not be replacing tee shirts every couple of months!
