Hi Justin,

 

Not sure if this helps for motion picture film, but this works for print photographs:

 

You can use a 50:50 mix of distilled water and isopropyl alcohol and a cotton swab for cleaning water soluble dirt. These are the guidelines given by Greg Hill of the Canadian Conservation Institute:

Dampen a cotton swab with the alcohol/water mix. Roll the swab lightly across a piece of blotting paper to absorb a lot of the liquid. Then, gently roll the swab across the surface of the print. Do a small test in a corner first to make sure the emulsion/gelatin layer is not sensitive to water. If you are cleaning color photographic prints, the image can go slightly milky on the surface, but that will disappear when the gelatin dries. Try not to scrub the surface. Some prints will also curl if the emulsion is wetted out in any way, another reason for using only a small amount of moisture. You should consider putting the prints between blotters under weights immediately following cleaning. If the surface is tacky after cleaning, let it dry somewhat before putting it between blotters. You may need to repeat the cleaning a couple of times to make sure it doesn't end up looking streaked.

Hello friends!

 

Has anyone find replacement for HFE 7200 film cleaner?  Not available from 3m anymore in Canada and being discontinued.

 

Isopropyl might be a swap.  For running specifically in a Kodak p200 film cleaner.

 

Any advice or contacts for discussion is greatly appreciated,
