"Might you be willing to post a working formula for the "gentle bleach" with instructions for use on the list?
 I'm too lazy to find my darkroom notebook now, but the formula goeslike this.
 15g citric acid
 10g sodium metabisulfite
 2g disodium edta
 70ml 60% ammonium thiosulfate
 water to make 1 liter"

I was wondering if this formula would be suitable for bleaching back inter-positives as part of the process of turning them into negatives for contact printing. On another forum a member reports having successfully used Kodak Liquid Developer System Cleaner obtained on an auction site and diluted, for this purpose.
