Hypoclear and permawash?

[Howard Tanger]

The reference was for toning a 'neg' not using selenium as a wash aid.

I see that but the subject of this thread is the use of "wash aids" not toning negs!
Cordially, Howard Tanger

There's an interesting and pertinent article on archivel processing at:

Best,

That was a very helpful article, thanks! It provided a very useful counterbalance to the less-specific NPS guidelines, which will come in very handy.

Thanks again,

Scott--

The National Park Service employs fairly stringent standards for archival processing and contact printing through its Historic American Buildings Survey/Historic American Engineering Record (HABS/HAER) programs. Here is what they say:

Hope that this helps.

With modern papers, such prolonged washing will likely wash out the whitening agents thus reducing print brilliance.

I use PermaWash for both film and paper - it saves lots of water and speeds things up. The sequence I use is the one found on the instructions for PermaWash with more time added to the final wash. Several years ago I tested my paper to see if it met archival standards and it does. A lot depends on how you wash your prints (archival washer, tray washer, siphon, etc.) and the quality of the water. If you are concerned about following archival procedure you will need to test your paper for proper fixing and washing - The Photographer's Formulary sells the tests in kit form with easy-to-follow instructions.
This is the sequence I use for film after fixing it:
Wash - 1min
PermaWash - 1min
Final wash - 5min

Fiber paper sequence:
Wash in archival washer - 5min
PermaWash* - 5min
Final wash - 20 min
* I add 20ml of Selenium toner per liter of working solution of PermaWash

Kodak Elite and Forte papers required a final wash of 45 and 30min respectively

Buy a large size jar of sodium sufite and weigh out 20 grams for ever liter of hypo clear . Much cheaper and just as good or better than what you buy at a camera store.
