Electronics people, do "zero residue cleaners" become stale?

[NeoPTLD]

I have a 3/4 empty can of "zero residue" cleaner really intended for precision electronics cleaning. It must be 12-15 years old.

It says it's good for "photographic film" on the back so I am guessing it's really supposed to be residue free. I wanted to spray the lens down with this, because wiping can cause scratches.

Not knowing if its really residue free, I sprayed some on a dark ceramic plate that I made absolutely sure its spotless to test it.

After it evaporated, there's residue that smells like rubber. No way I'm using it on my camera lens.

Did they make it like this or is this crap stale?

We have some similary chemicals that are >10 years old and work fine. Shake 'em up and go.

does it say whats in it? heh.

or at least what bad is in it? ie. warning contains""

edit doh. looked at the pic. ive heard that stuff work(ed) great, i think industry got rid of it because of pollutants or something, i forget.

I wouldnt use it on a lens though

i would not use it on a camara lens...it may damage any coating on the lens. (if there is a coating)
i have used similar spray that did did this to my CF reader

I don't think it's legal to use anymore. 😛
