I think I'm going to go w/the dishwashing detergent + water mix for my plastic screens.

I would love to air dry the prints if I only had the space!  I have room to dry 32-11x14's on the racks, but only one hanging.  I have a teeny film-drying cabinet because when I built the room I thought print drying space was more necessary.

I know all the books say to dry FB w/the emulsion side down, but it just seems like asking for trouble...so I bought a used dry mount press on ebay to deal w/the curl.

Thanks!
