I saw the same ad for Sports Wash and have been using it ever since. I am a firm believer in it. Several years ago I was in a make shift ground blind of brush and limbs and on 2 different times, I had a doe come within 12 feet of me before she realized something was out of place. Both times she circled me completely, but never spooked, she was just nervous.

I turn my camo inside out, it helps prvenet fading, and wash each load with a cap full of sports wash.

It work for me.

Good luck!
