"I have never figured out how to use retayne in my front loader. And I have a bottle of the stuff that I wanted to use wih a black fabric that runs does anyone know if the retayne will work if I put the fabric in a tub of water instead of using the washer?" (Sorry, haven't figured out the quote ability.)
Retayne works well in a tub or bucket. You need a large enough container/tub so your fabric can move freely in the hot water. Use a teaspoon of Retayne for each yard of fabric in hot water. When you put the dry fabric in, stir regularly for 20 minutes. Then rinse with cold water. (If I have several yards of fabric or more, I throw it in the washer at this point!) I hate to admit it but I usually throw in a Color Catcher for my peace of mind.
