I don't have experience with Arches HP, but *maybe* it's similar to
Bergger COT 320. IIRC, Bergger COT 320 is (kinda) rebranded Arches
Platine. If so, develop in bottled drinking water (pH <= 7), and then
try to clear in mild citric acid (1 dessert spoon into 1000-2000ml)
and see what happens. My experience with COT 320 and this work flow
was positive; the paper cleared completely and relatively quickly.
Hope this helps,

> I am working with Mike Ware's new cyanotype using Arches Hot Press. I have been concerned that my highlights are a little pink/beige - maybe a shade darker than the paper base, which is certainly far from bright white. I like the way the images look - especially compared with either Buxton (fast but very contrasty) or Platine (just too much blue all over), but wonder if there is a problem with clearing and whether the photographs may be fugitive/will deteriorate at some point. I use a drop or two of citric acid in the emulsion, mixed in just before using it, and I wash my prints, gently, for 20 minutes (well water - no chlorine).
