In my opinion, color catchers are a waste of time and money, especially if you have an "efficient" (snort) front loader. I read all the time about how people wash things with color catchers over and over and over, and the fabric still bleeds. Just put it in a top loader FULL of hot water and a teaspoon or so of Dawn, let it sit overnight, then drain and spin. If you don't have a top loader, use your bathtub. The fabric needs plenty of hot water and front loaders don't check that box.
