So, since it seems I can't get Farmer's reducer in Canada... anywhere... I've started using a small batch of bleach fix left over from my last batch of colour printing to to try out this whole bleaching thing.
Should this work? Seems to be bleaching the prints and gets rid of pinholes nicely, but am I setting myself up for any long term problems?
Well RA4 bleach-fix appears to work and if it was left over from RA4 printing it might well have made sense on cost grounds to have used it but can it lead to later problems as the OP has asked?
