When soaking in the Retayne, leave it over night. My hot water heater will heat up to 150 degrees. I use the hot water and let it soak for several hours, usually overnight. Just a thought I prewash everything and use Retayne on anything I think might bleed. It works for me. I figure fabric is too expensive to ruin a quilt for a bleeding piece of fabric. This is of course MHO.
