I've got a bottle of Kodak Film Cleaner that I've had for about 15
years or so. Does anyone know what the shelf life is? Is it still safe
to use?

Trichlor is now considered an environmental hazard and may be a
carcinogen. Avoid the fumes and use gloves.
Kodak's current recommendation is to clean film with very pure
Isopropyl alcohol. The purity is mainly to avoid water. The alcohol
itself is "dry" and won't swell or streak the emulsion. The drugstore
variety, which is about 91% pure is not good enough. You need 99+%
pure. Its available as an industrial cleaning solvent at reasonable
prices.

I also use 99% alcohol. Some drug stores carry the 99% instead of the 91% or
typical 70%. Watch out that stuff burns! Great fuel. :)

Was it, 15 years ago? At some point, film cleaner was commonly Carbon Tet.

It's about that old from what I remember. The label says it contains heptane and
1, 1, 2 trichloro- 1, 2, 2 trifluoroethane (Kodak Film Cleaner, Cat 195 6986)
