Color catcher is an item you can buy in your supermarket, wal-mart or what ever. There are color ones and Woolite makes a Dye Magnet that is like a dryer sheet. There are 20 of these in a box. I think it is well worth the money. Throw that in with your faric when you wash it and you will be surprized about what it picks up. I also have a cloth one I got someplace. But I really like the hot water in a clear glass and a small square in of the fabric in it.
