Remove your acetate film from any sealed, airtight metal or plastic film canisters. Sealed film that is not allowed to breathe will continue to deteriorate.
Place the film in a storage container such as a freezer in temperatures below 50 degrees F. Very cold temperatures will drastically slow further chemical deterioration to your film.
Leave the film in cold storage until you are ready to have it duplicated. Gather your film and place each in a separate container.
Bring the film to a professional film digitizer and ask to have the film digitized. This is the only way to save your film from the effects of vinegar syndrome.
