Is this mag. stripe with an image on the film- or fullcoat with no
image?
I never saw anything that was so bad it needed cleaning. Especially if
it's fullcoat 16 mm stock. "Renovex" or "Vitafilm" can be used with
ventilation to condition nitrate or cellulose acetate based film.
I don't think anything will help bond the oxide back to the base if the
binder has dried out. I'd try a little test with Vitafilm or Renovex if
I had some junk stock to do it with.
A lab might be able to do more than I'm aware of. My techniques are
somewhat antique, but I know they work with film with an optical
soundtrack.
If the film is just non pliant due to dryness, that might be why the
oxide is falling off.
BTW, Renovex and Vitafilm will dissolve tape spices, plastic reels, and
film cores. I put the film on a metal reel or core for processing. Tails
out.
