I had a problem with reds also (I'm not even sure of the brand name), but I ordered Rit Dye Fixative off the Rit website -- It cost more to ship it than the stuff did, but it sure worked. I had washed this red material many, many times, used so many different remedies that didn't work. I was afraid I was going to trash the quilt I was working on! This stuff saved my neck -- it works. I've used it on very bright blues and greens (which also tend to bleed). I wouldn't hesitate to use it again and again!
