Pec-12 safe for Kodachrome(current stock)???

DanielStone · Apr 15, 2009

hey all,

was scanning some of my newly shot kodachrome last night, and noticed that there were some stuck dust particles to some of the film. So, out i got the pec-12 and a few pads to clean with, but after cleaning the slide, i noticed that there was a pinkish residue on the pec-pad.

i immediately stopped, and did not continue. it got the dust off, but do any of you know if this can harm kodachrome?

help would be appreciated. Since i am wet-mounting the kodachrome, i want to have it clean before I scan. I just DON'T want to harm my film.

I've also had a problem with a residue sometimes being left on film(e-6 and c-41) after cleaning with Pec-12. Didn't show up in the scans, but don't like the idea of dirty film, eww.....

Thanks

i have also heard of people making a diluted solution of de-ionized, de-mineralized h20. the idea is to make a less-concentrated cleaner. any experience?

I thought Kodachrome was lacquered as the final step of processing, or is this info hopelessly out-of-date?

I've been told that the first cleaning of kodachrome causes something to come off of it and that this is nothing to be worried about.

A google search for pec12 msds finds...

Section II Composition and Ingredient Information
Chemical Identity :
Methanol, CAS# 67-56-1
N-Butyl Acetate CAS 123-86-4

Old Kodak film cleaner was hexane a petrochemical solvent, not an alcohol. Is either safe? I don't really know.

Yes, several decades out of date.

Hi Daniel, which scanner software are you using ? Have you tried SilverFast ? I'm very pleased with the results.
They have included a dust & scratch removal tool for kodachromes a couple of months ago. (Also new are Kodachrome IT8 targets.)
Perhaps this is a safer way than possibly ruining your film.

hi,

i am using an Imacon flextight 646 scanner. it is at my local photography center (covina, ca). I have had no problems scanning so far, just using the standard rgb settings as a starting point. since then i have created some profiles that i use, mostly with a minor curves adjustment to bring up shadow details a nudge.

otherwise, no problems, still can't figure out what the pinkish cast is from.

if anyone knows, please let me know. i don't want to harm my film!

thanks
