The wash removes undeveloped SolarFast dye from prints and reduces the risk of back staining during washing. This is especially important for preserving white areas and highlights when making photographic prints on fabric or paper.
Instructions: For machine washing, use 3-4 capfuls (24 ml) per load. Set washer to hot for best results. For front loading machines with a pre-wash flush, add SolarFast Wash between and the flush and wash cycles. For hand washing fabric or paper, submerge in hottest water possible, add 1-2 capfuls (10 ml) SolarFast Wash, agitate constantly and keep water flowing 10 minutes.
