I've been going through a few old Technofilm cartoons. On one, I noticed a kind of breakdown of the back surface of the film. Almost a very slightly moist effect. It's like the film may have been damp, or stored in a damp place, resulting in small parts of the film going like this. Fortunately, such problems are only present in the first minute or so of the print, and in the rest, colour and sharpness are fine. I'm sure, however, that these problem areas get worse every time I view. My question is this; how do I remove this? Film Cleaner? Anyone else had this?

Wow, I never ran into that Simon. Where was the film at? Moist or dry environment?

Before I purchased it...I think it looks like it's been somewhere a bit damp.

Can you buff it off? It might be one of the hundreds of "film treatments" that were popular to lubricate new prints. Sound like a little too much but I doubt moisture which would have lead to mold on the emulsion. In the olden times, Kodak would lacquer Kodachrome coming off the processing machine and sometimes moldy film could be saved by removing and re-lacquering the film. This wasn't done on release prints or Eastman positive or any of it's competitors (Fuji, Agfa, Gevacolor, Owrocolor, etc).

Having tried to clean this substance off the film I found it all came off leaving nearly clear film! I used proper and known quality film cleaner. It's as if the whole film is breaking down as it also tears quite easily. Fortunately, as I said, it's only right at the beginning of the film!

While I worked at Ilford Films here in the UK I had seen b/w film where the gelatin had been attacked by a fungus.
This tended to be caused by damp conditions and there isnt really too much you can do about.
It sounds like the same problem you have here.
