Digital BW, The Print

If I understand you correctly, that fixing, then washing, followed by selenium toning, is what you are saying, then that would lead to very unhappy results.

Selenium toner contains very substantial quantities of ammonium thiosulfate (rapid fix) and therefore any selenium toned paper would have to be re-cleared and rewashed afterward.

Apologies if I misunderstand the order of process you intended to impart.

Added to that, you could still use selenium toning after the complete treatment to improve the archival quality. I did a lot of selenium, a lot of Sistan but not both.
