I have used the color catchers for several years while dying fabric for my rag rug business and been amazed at what they can do. Oxyclean is also good. In my experience, you can't put too many color catchers in the washer.
On another note, Bootsie and Mittens have cornered a mouse and had great fun catching it and letting it go. The last time they did that it got away. I helped them disable it this time. I have my boundries.
