    One of my criteria when making my OF-1 was that it should be less smelly than both TF-3 and TF-4. Even TF-4 is a little more alkaline (and smelly) than needed.

    Maybe it's time to introduce "OF-2" - same as OF-1, but with far less alkali?

    A tablespoon of sulfite should make a fine wash aid. If your water is hard, you could get sodium hexametaphosphate as some suggested, or Calgon from the grocery store. The active ingredient used to be hexametaphosphate, but is now some kind of citrate, I believe. The detergent in the Calgon should help too.

    If you've not yet you may gain some insight to
    Mr. Troop's thoughts concerning fixers by visiting
    rec.photo.darkroom. Search that NG for, alkaline
    ph 10.5 .

    His comments concerning Eddie Ephraum's brew
    are interesting. Dan
