[KISS BOB]

DEAR MARK,
      As I mostly develop (COT 320) in Potassium Oxalate, 
I start with a 1% oxalic acid first bath for 5 mins, then 
two 5 min clearing baths made of EDTA and sodium sulfite, 
followed by a last bath of working strength Kodak hypo 
clearing agent. I checked with Dick Arentz and Eric 
Neilsen and both said this procedure would do the job.
      If I keep the first Ox Ac bath fresh I get good 
clearing.  The few times I have used it too long I have 
had residual FO in the paper.  Next to the cost of a print 
and the time to make it, Ox Ac is pretty cheap so I mix it 
fresh for every printing session.
                 HOLIDAY CHEERS!
                     BOB
