Digital ICE not working on B/W

Try Tiger Cloth without any fluid at all. Amazingly good, doesn't scratch (but I keep mine in a ziploc...might accumulate dust otherwise).

But yes, final rinse with distilled water works miracles in the first place...followed by brief dip in distilled water with 3 drops (no more) photoflo per 500cc.
 
Thought the detergent works, $10 of photoflo will likely last longer than film is produced or I die, whichever comes first. $10. That's not much compared to film.

Who knows what non archival properties detergent has. I'm not risking my film with it.

Generally, a thorough wash, and final wash with distilled water and photoflo (freshly made!) and then hung up to dry in a relatively dust free environment will get your pretty darn clean negs. I had to move my wash to distilled water because the local water here was leaving some kind of oily residue on my negs that the final wash was not taking care of (yes, it wasn't from photoflo or anything).

When it comes time to scan or wet print, I bought a couple of fine tipped brushes for getting the dust off. Hold the neg up at an angle so you can see light reflect off of it and just get the couple pieces of dust that might be hanging out (I usually have 1-2 per 10 frames).
 
I use a dust blower, if you do a lot of scanning and printing in the darkroom compressed air gets expensive, fast. A good tip is to not buy one of those tiny little 'photo' dust blowers they sell in camera stores for 15 dollars. Go to any pharmacy and buy a rectal syringe. It's quite a bit bigger than most of the 'photo' blowers, and it only costs 5 bucks.
