    Is there a way to test your print after going through the washing process to see if you removed all the fixer? I don't have a pro washer and have been using two tubs w/ agitation and running water with a tray of fixer remover between the two washes and the prints look clean but how do you know for sure?

    PF sells a residual hypo check as does Edwal (or Edwal did, not really sure if they still do).

    The at home test is the HT-2. Ilford's formula; a 1%
    solution of silver nitrate. The test is done drop wise
    so very little of the nitrate will go a long long way.

    Test using a procedure you feel of interest. An
    example: after fix a rinse a hca a rinse then hold.
    After hold a first tray wash; one hour. Then dump
    or transfer for a second two hour wash. Agitate
    intermittently both washes.

    Conduct test in subdued light and check soon after
    blotting dry. Test dried paper and leave the drop or
    drops on for 3 minutes. To evaluate results bring
    lights up some. No stain is my standard for a
    clean print. Dan
