I use ilford rapid fix at 1+9 and fix for 2 minutes, then transfer directly to the hypoclear for 10 minutes, then into water for anywhere from 5 minutes on up, and then directly to the selenium. never had any staining problems and my selenium toner lasts months and months. i think washing your prints to completion before is a bit of a waste of time - after all selenium toner has fixer in it, why wash it all out just to put it back in and have to wash all over again?
