Response to reducer for retouching black marks on prints

This quetion is on the wrong forum. I have a formula for iodine reducer on the Formulas page of my Unblinking Eye web site. For reduction to total white, you might try a lesser dilution than I recommend on the formulas page--maybe 1:25 or 1:40. As George mentioned, you must refix and wash very thoroughly. And be sure your print is thoroughly washed before you use the reducer. A post on the Printing & Finishing forum states that iodine bought from the drug store works equally well. Be sure to test your spot reduction technique on a test strip before you try it on a fine print.
