Using water is dangerous for either glass or flexible support negatives.
It swells the gelatin which may not be in good condition and there is a
danger of its tearing or even coming off. If the gelatin has been attacked
by fungus it may even have become soluble.
The recommended cleaners are "dry". Currently Kodak recommends 99+% pure
Isopropyl alcohol for negatives. Probably not suitable for colodion. The
solvents recommended in the past are now considered environmentally
hazardous or toxic.
