I fix bleeders like this: a couple drops of Dawn, hottest water in my washing machine, fill to the top (I have a top-loading Speed Queen), let it agitate a minute, then unplug and leave overnight to soak. 12 hours later, plug back in, cancel cycle so it will drain and spin. Re-test fabric for bleed. I've been able to fix every bleeder I've ever had using this method.

I have used Retayne and the directions say after the hot wash use cool water washes. Maybe after doing the Retayne try a cold water wash and rinse with color catchers and see what color they come out.

Yeah!! Success!! Thank you so much for the methods on treating and the tips for soaking and rinsing!!

I tried a new batch of fabric using hotter water and I'm sure that helped a lot! I heated big bowls in the microwave and added to the hot tap water with Retayne - yes there was bleeding. Soaked and stirred periodically for about 4 hours - then next l took individual cuts & did a first rinse with warm water.

I wanted to be able to identify which cut might be a bleeder so I cut a color catcher sheet into small 1.5" x 2" rectangular pieces. & added these to the next rinse - yes a few were still shedding dye.
I set up a bit of an assembly line after soaking & treating and that first warm rinse - I next hand washed the individual cuts in my sink - it had warm water with the "clear/colorless" Dawn detergent - next rinsed in a large enamel pot with warm water and a color catcher piece - and last did a cold water rinse with another piece of color catcher in a big aluminum baking bowl. Yeah!!!!! There were very very few that still had dye so basically no more bleeding!! For those that still had some bleeding I just retreated for a shorter time period. and went through the rinsing process.

LOL With my assembly line working so well and being easier and quicker than before I'm kind of on a roll and treating a lot more pieces than what I will need for this project. Since I had it set up I thought I might as well get a bunch done!

This has been a good learning experience! Thanks again for all of the great info and help! I truly appreciate it!
