I have a can of compressed air that I want to use to do some dusting on my PC components.
I tested it on an old keyboard and on the odd occasion some liquid comes out. I am worried about using it on the components. I am following the instructions and doing very quick presses at the recommended distance.
You shouldn't get condensation from canned air if you're holding the can correctly (vertically). Condensation only happens when you're using it at funny angles.
