RE: Pt/pd clearing poll (was Potentially stupid pt/pd question)
For Ziatypes: Developing: No development, full printout, I directly start to clear. Clearing: 2 x 2% Citric Acid, 4 mins. each, continuous agitation, lifting (alternating corners) and let dripping 1-2 times every minute Rinse: w/ tap water for 10 mins. changing water every minute. * That's for coating solutions which doesn't contain gold and/or platinum. If I have some gold and/or platinum in the coating solution then I also use a 2% Na4 EDTA + 2% Sodium Sulfite bath (after citric acid baths), 10 - 15 mins., occasional agitation and lifting (every 4-5 minutes or so), then I rinse as described above.

So I'm conducting a quick little poll. What chemistry do you all use to clear your prints, how long, how many different baths, etc.?
