You don't need anything special, just use an air duster can for cleaning keyboards and such and turn it upside down. Turning it upside down makes the liquid CO2 come out instead of air. Used that before to unstick a boat pedestal seat.
I wonder if that "thermal freeze spray" is just the same thing but with a tube inside of it so the contents on the bottom come out instead of the contents at the top.
Could be.. I always thought the old cans were freon, not sure what is in the new ones. I have been out of that line of work for decades, but it was just another handy tool to have.
