Hi,

A few weeks ago, having been given the advice to use canned air for cleaning the insides of my box I went to the computer hardware store I frequent and bought one. Heck of an expense, but nothing's too good for my machine. When I was using it, I noticed the can became very cold after a while. Also, some sort of sedimentation appeared on the sensitive parts I had been cleaning. It was moist - like frost - when I touched it. I looked at the can. It claimed to contain a butane-propane mixture..... now, it DID say it was intended for cleaning sensitive electronic parts, but I wonder.... any surface this mixture hit would get very cold, and I think condensation may have formed on it later - water.... plus, while it was removing most of the accumulated dust, some was made to stick to the surface, mixed with that sediment, which would then dry up pretty quickly leaving a thin, caked film of dust behind.

After cleaning I had problems with my video card - the screen looked jumbled during loading, then it went blank, the little LED light on it indicating there was no signal. I took the card out of its socket and put it back in again, waited awhile (thinking the scary thought it may need to dry up a bit), then turned the computer on, and everything was OK.

So, I'm a little worried (corrosion?) and unsure of whether I used the right product for cleaning the dust out of my computer. I know you can also get cans of simple, compressed air.... why use a lighter-fluid mixture?

Thanks,
