I use 16 gram CO2 cartridges for emergency filling of bicycle tires. Saw a
gun designed to incorporate them into use on computers and bought it. It is
kind of week, short lived and expensive @ $2.5 each. Hadn't considered the
environmental aspect. But it is rare-use.
Also have a vacuum cleaner attachment for keyboards. It has 23 tubes, 3/16 x
4 inches, with tiny brushes on the ends. Looks like a strange sex toy.
Can't remember where I got it. Surprisingly, the silicon rubber tubes are
still very bendy.
Works really well but I don't know about components with the brushes.
