    Agfa recommends a sodium sulphite bath to "stop" Viradon toning. And I'm sure it would make washing more efficient. It also seems to help clear the yellow tint to the paper quickly

    Viradon - and at least most other polysulfide toners - continue working in the wash water. To stop the toning and remove the milky film of elemental sulfur on the surface of the print, use a sulfite bath. Strong HCA is fine, or just a solution of 200g sodium sulfite in one liter water. Same as you would use to clear polaroid T55 negatives (I use the same soup for both).

    When fixing in plain hypo, a longish fixing is necessary. Depending on temperature, agitation, concentration, type of print and required "archivability", about 20 minutes should do it.
