I live in the desert and I feel may Pancro expires quickly from the extreme heat. Leaves nasty residue. When I buy it new it is always great. Anybody else have a similar experience?

I recommend what I was told when I worked at Kodak, keep the unopened film in the freezer or refrigerator.

Most lens cleaners have alcohol content in them, which explains evaporation. For example, from the Material Safety Data Sheet (MSDS) for one product:

Section 3: Composition/ Information on ingredients​
  • Ethanol, 2-butoxy (alcohol)
  • Ethylene glycol
  • Water
Pancro lens cleaner MSDS lists nothing but isopropanol

Alcohol has no expiration date.
