Also compressor air sometimes has a lot of moisture .
Actually, that's a good point. When I worked in the underground environment we ran our tools with compressor air and used dry air to fill our splice cases (to keep the water out).
So you could blow moisture into the deep dark crevices, then have rust damage and have no idea why your gun's not working as well as it used to.

I'm no expert, I'm just, well---opinionated!
