When optimum permanence is needed, perhaps for archival storage of prints, the following fixing and washing sequences at 18-24ºC/65-75ºF (including wash water) are recommended using ILFORD WASHAID (Ilford's version of Hypo Clearing Agent). Do not add a hardener to the fixer. Be careful not to exceed the capacity of the fixer and not to extend the fixing time as both these make washing more difficult.
Optimum permanence sequence with selenium toner for fiberbase prints:
ILFORD RAPID FIXER (1+4)
Selenium toner diluted with
working strength ILFORD
WASHAID instead of water,
ILFORD WASHAID (1+4)
Fresh, running water
There's no mention of any step between fixing and toning, so presumably the print goes directly from fixer to toner, as recommended by AA. He used plain hypo w/ sodium sulfite (inhibits staining) as the second fixer, prior to toner, perhaps to mitigate the hardening from Kodak Fixer (1st fixer).
