I stand by my post about vinegar! I soak all dark fabrics in vinegar before I prewash. Why would I prewash the fabric, only to risk it possibly fading before I soak it in vinegar? The "whole process" takes about 5 minutes of my actual time as I don't stand there and watch it soak for an hour. Unless you have tried vinegar and had it fail, you are spreading false information about vinegar and advocating dumping more chemicals into our already polluted water supply. I knew I would get flak about this, but, as I said, vinegar has NEVER failed me and I buy a lot of fabric at JoAnn's, WalMart, and Hobby Lobby. Again, I suugest you not knock vinegar unless you've tried it and had it fail. Geez!
