One site said you had to use prewashed fabric. Here's a link promoting the product.

Also, while looking around the net, I saw people where suggesting rust removers. I'd be very wary of them. They may whiten whites but are damaging to colors. I had a light tan tshirt with rust stains and use a rust remover for clothing. It bleached out the color to a pinkish tan. Unfortunately it "was" my husbands tshirt.
