My Champion fleece knickers bled on one of my saddles! It turned blue. Luckily, the bike is blue, so it's not that bad. I tried a bunch of products, but nothing really worked. Over time, it has faded a good bit. I've washed the knickers a bunch of times and they still bleed when they get sweaty, so I figure that I can only wear them on that bike now. Then the saddle gets a new coat of blue. It always seems to fade again later, but I don't think it'll get really white again.
