You'll need to find the RIGHT duster gas. There are two out there. One is the stuff you find at costco, staples, future shop, london drugs etc. the other is a bit harder to find and AFAIK is only available from industrial/computer supply companies (I don't have a list of these as I'm not in that field) since the other stuff stopped being sold at regular consumer electronic places for some reason or other.
The stuff you want is Tetrafluoroethane so read the label carefully most consumer electronic places will sell Trifluoroethane instead.
Not trying to step on toes, But the industrial application name for Tetrafluoroethane is HFC134A, thus he was on the right track. Just trying to find a source.
IS THE ONE YOU WANT.
Its cheap and its 134A. Its avaliable everywhere (usually) or you can order it online.
You do need to check the label very carefully as only the "special application" brand of Falcon Dust off is HFC 134A, all others are 152A or 1,1 difluoroethane which is not what you want.
