    Perma-wash is a "soapy" and "bubbly" wash aid, used like hypo clear but not, strictly speaking, hypo clear. The manufacturer makes all kinds of claims for it. I don't personally believe them and I don't think many others do either. It seems to be surfactants, which is very different from the way regular "hypo clear" works.

    Are you using the wash aid product called Perma-Wash? Is that what you mean?
    I'm using Ilford wash aid...

    Well, it looks like there was some confusion over the bubbly solution comment. Sorry if I erred.

    Now, back to the Sulfite washing aid. This and several other salts will accelerate washing. The same thing is achieved by the use of an alkaline or neutral fix. However, for those concerned, if you use the guidelines regarding the Kodak retained hypo test you will see that the "acceptable" level is still colored a bit indicating that some level of hypo is acceptable. And the tests that Ctein made and wrote up shows us that some low level of hypo is needed for archival stability for the prevention of bronzing and other undesirable effects.

    I can add this. I have worked in three production labs, and I have prints from all of them that date from the 60s. None used any sort of wash aid and all were on FB paper. All are just fine. Some are on display and others are in albums or boxes. There is no problem. We did not use it at EK in our processes either.

    We used water from the lake here processed in the water plant and delivered to our lab taps. Just plain old Dihydrogen Oxide.
