    I didn't really think of that.
    No sense in using film that's already over the hill. It will only pick up speed.
    Which is why I previously posted:

    Vinegar smelling film

    Strange question. I often use milk to dissolve/nullify the effects like acidic things like battery acid that has collected on metal contacts etc.

    If I were to soak the canister and tin in a milk bath, would that nullify any acid that may have collected on those items so that I could safely use them with other films?

    I'm not that great at chemistry so maybe what I'm saying is really dumb?

    For that matter, is there anything I could soak the film in that would halt the vinegar process? (That would still make it usable) or is that just crazy talk?

    Is it possible for nitrate based films to spontaneously combust? I have seen how fast this stuff can burn!

    I think beyond the acid problem this is one thing I'd really be concerned about.

    If you have any yea, take a look at my gallery, probably on the most recent page, there are two images of how fast it burns

    If you could find such a substance and get it to market you could be a very rich man!

    Milk is somewhat acidic (it contains lactic acid) - my guess is that it might be the fat in milk that's helping more than the milk itself.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    Oh haha, hmmm well then, so what could I use if anything for the canister and the tin? Or is that a lost cause?

    Milk curdles in acid due to a reaction with it. Even though it contains lactic acid it can react with acid and eat it up. However, nothing will stop the decomposition of the film once started. It goes and keeps going until it becomes entirely useless. The film you have Stone is bad. Face it and move on! Get rid of it.

    If it was nitrate film, remember that this is akin to gun cotton and is actually nitro cellulose. Look up the properties on the internet. Not good stuff.

    I know the film is bad, I'm interested in salvaging the canister haha, I guess if there's no way to stop the process, even the residue on the canister is probably "dangerous" to other film then?

    I've already burned the old Nitrate film, didn't you see my gallery where I took pictures of how it burns?
