i don't know that this will work at all and it might leave a purple stain on your prints. in areas where water hardness is a problem and high iron content can stain plumbing fixtures, the ingredient the water softeners use is either sodium or potassium permanganate. it is available in small quantities as a liquid concentrate that looks a lot like iodine soap. you can was the print with this and it will reduce the iron stain some, but i won't promise it will remove all of it. getting the purple stain off the print later can usually be accomplished with a long water wash, but it is hard to get all of it out. your best bet is just to reprint these and on your drying rack, you can get split or spiral wire loom from an automotive parts store and use that to cover the bare wires on your drying rack. my personal preference on a drying rack is to use print rollers, like the wringer on an old washing machine, and then use a blotter book. less contamination, and the blotter book will force the prints to stay flatter as they dry.
