I use the Shout color catcher. It works for me if I prewash. I am not a prewash person though. Might have to on my red and burgundy batiks. Have had good luck with no bleeding on my batik quilts and I have done many. My favorite fabric. I do have retayne to use in teh sink to soak. If it bleeds the sink is great for washing out with lots of cold water.
