Shout's Color Catcher is usually found on the top shelf at the grocery store where washing items are located.It really gives you a clue if it catches color. I wash with a small bit of cheer for dark colors, delicate cycle, cool water. Just did the process on a red and was pleased to find the CC a tad pink and the material not much changed in feel. If there was a greater problem I would use white vinegar and salt in the water as it gets washed again.
