Re: P/P and different developers

My two-cents worth is this: potassium oxalate gives simple and effective 
relief to many of the problems people encounter with citrate developers.
Smoother tone with less tendency to go gritty, etc, etc. It's available from
the usual suppliers but you can make it up yourself from oxalic acid and
potassium hydroxide (lye) quite easily and cheaply. You need a source for
the oxalic acid in bulk at cheap prices, and it will entail a hazmat charge.
I've been pleased with the service from:

Many chemicals will effectively reduce a Pt/Pd print, but in my experience
nobody does it better than PotOx.
