Quote:Alright, I just got some Dust Off Professional from Costco, a 6-pack for $14.something. Anyways, I followed the directions and decided to spray out my keyboard first as a test run before hitting up the computer. The first few sprays went just like the directions said they would (BTW, I have never seen so many WARNING instructions on NOT inhaling the gas on one object in my life... I'm counting. . . 7 total warning and caution signs all over the can). The last two sprays spewed out some sort of liquid that dried almost instantly, but not something I'd want to subject my CPU to either. I made sure the last two sprays were 2" away from the keyboard, but I had to turn the bottle on it's side to get into the cracks and crevices; maybe that was why the liquid came out? I think I'll try dusting a few more things with the spray until I'm 100% confident it will not harm my computer.
When you use the spray for longer time continuously the outlet gets so cold that the out coming gas can liquefy. Should not be a problem because the stuff should not be conducting. You might be careful spraying too long on some parts though, if they get very cold you might get water condensation, so indeed switch off the electricity first.
or what Pete said....
