I do citric acid followed by 2 baths of hypo mixed with EDTA. Watch out that your water bath is acidic - if it's basic it can lock in the ferric. That's why I go straight from the pot ox to citric acid.

I hate to keep harping on COT320, because Bob likes it and obviously has no problem-- and I'm sure other people do as well-- but that is the one paper that I had a heck of a time clearing. Maybe it's my water over here. But with both Arches and with the Revere, water baths and citric acid/water baths seem to be fine for clearing. But I'm sure what you're doing now would work as well-- seems a little overkill-- but if it works for you . . . :)

>> With the Fabriano, after development, I let the print sit in a tray of water for 5 minutes, and then 3 successive baths of 5 minutes each; 1) 2% citric acid 2) Kodak hypo clear with a TBS of EDTA Tetrasodium per liter, 3) another tray of Kodak hypo clear with EDTA, and finally a wash in running water for 20 minutes.
