I'm really beginning to wonder just what it is I'm not doing to my 
slides that everyone else is doing which makes them mine not require 
cold running water, ammonia, kim-wipes, PEC, and so on...

I mean, I know B.C. is known for it's pristine water and air, but what 
exactly is it that you guys are finding all over your slides that 
requires such drastic measures?

I'll admit, I have a few that have been mistreated, usually by the 
processor, and sometimes they benefit from a good rewash in warm water 
and a spot reducing agent like photoflo, but they are relatively rare also.

If I do anything, I give them a blast with compressed air, in most cases 
that's all that's needed.

On a similar topic, today I saw an ad for Nikon's ED 4000 scanner, and I 
have to admit the ad is pretty impressive.  They show an image of a 
gorilla which is very dirty, dusty, scratched, badly faded and other 
wish abused.  They then show the result from the ED 4000 after 
application of ROC and ICE.  It really does look like a different image, 
color is restored and defects are gone.
