Easy. Fill up a sink or a bathtub, hand wash,
And let soak ( I soak for 15 minutes because I'm a nasty ----head ) the water turns a grungy dark brown or yellowish,
You know it does the job. Hang dry and done! This stuff is what I trust to clean my expensive gear and keep it in shape, wraps, sleeves, slippers, spud inc straps, bench shirts, deadlift squat briefs all of it. And the smell is amazing. Buy this stuff, it's what you need to keep your investment performing.
