Hi, all. I have purchased some citric acid powder to use with my procion mx dyes in lieu of vinegar, to dye silk scarves. Problem is, I can't find adequate instructions for utilizing the citric acid, and wondered if any of you have used it? I even talked to a gal at DT where I bought it, and she couldn't help... suggested I check with you, Paula! So if you or any of the forum members have experience with it, I'm just wondering if I can pre-mix with water to pre-soak my silk, or do I need to mix with my dyes?
