Thanks, Scissor Queen,
I looked on the internet and found them both. I think I would not need the retayne. I also found that synthrapol might be found at places like Walmart or grocery store laundry aisles. It's just a soap.
I tried some of the red today in cool water. The water did turn a little pink. This was some red fabric that I bought yesterday, but some of the other reds that I have been using may be many years old. I'll have to test more of them with a wet paper towel to see if they release color.
