I followed the directions- sprayed upside-down until no foam came out.
Worked once.

Then the next time I tried to use it, nothing came out, so I pulled a
little harder on the trigger and broke it.

Now I have no idea how to dispose of the can- not for recycling, but
if I put it in the garbage, when the truck crushes it it'll make a
mess.

Guess I have to wait for Hazardous Substances disposal day (every few
months around here).
