Re: [ARSCLIST] Mag on film cleaning

Wow- that really is a tough road to hoe.

I would recommend you contact Mr. Edward Stratmann at the George Eastman
House in Rochester NY or Mr. James Cozart with the Library Of Congress
Sound and Motion Picture Division and see who they can refer you to. 


Both gentlemen are, as far as I'm concerned, the "go to" authorities in
this area and will not steer you wrong.

There is a lab in NYC " Vidipax" but I don't know their level of film
expertise, especially in extreme cases.

Best Of Luck, and I'm glad at least you don't have VS to deal with. At
least for right now. Low temp and low humidity will help stave it off. 

Cordially,

Bob

Bob -
It is mag stripe w/ images.  It's camera original newsfilm, some of 
which has literally been through a hurricane, so it will need some 
cleaning.  It is has tape residue and dirt in the image area, and the 
occasional dirt embedded in what is left of the track.  It is pliable, 
not suffering from vinegar syndrome. 
Is there not a standard procedure for labs for dealing with film w/ this

kind of damage? 
Thanks for the info!
