We have had some recent discussions about dust on the camera lens and/or
on the digital sensor. 

Dust on film or on a slide will affect the results from a film scanner, as well. 

One of my nearby camera stores suggested using these products ...

Dust-Pro 2000 [UPC 17506-21606]
http://www.pecaproducts.com/cannedair.htm

PEC-12 Archival Photographic Emulsion Cleaner
[UPC 95122-01011]
http://www.adorama.com/CHPEC12.html

and
PEC*Pad Non-abrasive Wipes
[UPC 95122-05011]
http://www.adorama.com/CHPECPP.html

I'm sure that other similar procucts are available -- does anyone have any
additional suggestions?

Ahh - PEC-12 with PEC Pads!
Used that stuff for years. I knew a guy who wet-ragged it, too (an odd little duck, but he was a good printer)!

Good stuff - liked it better than the Kodak stuff we used in college (name? - not Photoflo, but the neg cleaner?)

Yes, spray PEC-12 onto a side of a PEC Pad and fold it over/around the film (I know I'm not explaining it well, but I hope you get the idea) and gently rub. When printing entire rolls of film in minilab equipment, we'd do the spray, fold it over the film at one end, pull and "squeegee" all the way down to the other end - wipe the whole roll, basically, in one pull.

You can actually be a bit abrasive, but don't get carried away. Cleans most everything off of film.

The affected results of dust on the film will be black dots for transparency, and white dots for negative. Either way, it's a bit of time in Photoshop to clean it all up. Be sure to spray it with canned air - actually, air coming from a compressor is best, as canned air can "sputter" all over your film - before doing the actual "scan" as that will help knock off whatever dust fell on your film between the PEC Pad and placing it in the holder.

Hmm 1 grain of sand and you have a scar on the film from beginning to end

No - by the time it gets to there, there's nothing on it but some dust that has landed. It comes out of the film processor (all the developing and cleaning baths, and a dryer) and you hang it on the rack next to the printer. Whatever dust is in the air between haning it and "squeegee-ing" it is all you're wiping off.

The PEC wiping process just SOUNDS worse than it really is.
