SolarFast Wash is a high-strength, concentrated scour/detergent used to remove undeveloped SolarFast dye after exposure to UV light. It is highly effective for preventing back staining during washing. This is especially important for preserving highlights and white areas when making photographic SolarFast prints. Works even better than Synthrapol because it is very cationic, and has a magnetic attraction to the dye molecules, keeping them away from the fabric. Works great for washing out Fiber Reactive Tie-dye too! Use in the washing machine (24ml per load) or for hand washing (10ml per print), with HOT water. Adding some soda ash to the wash helps too, with fabrics that really hold on to the excess dye, like silk. Yellow SolarFast is more difficult to remove the excess, also mixes that have yellow in them, so using a little soda ash really helps keep the white areas white! Please note: SolarFast Wash does contain a small amount of phosphates so Jacquard recommends it NOT be used with Cyanotype prints.
