Is there a way to use only part of a can of urethane insulating foam spray, and
save the rest to use later? I find if you don't use it all right away the nozzle
and dispenser tube permanently clog.

On rare occasions I have been able to get an extra use from the spray
cans by blowing out the tubing and can outlet with compressed air. A
shot of lacquer thinner helps somewhat. Long term, though, it is
pretty much hopeless. Sure would be neat if they marketed a much
smaller sized can maybe in four packs for those many small jobs we
have to do.
