I have a can of Blow Off duster - it's the stuff previously mentioned, coming through Computer Plug Inc.
It's got an after-the-fact label put on it declaring the contents; along with the 1,1,1,2 Tetrafluororethane, it also lists petroleum hydrocarbon.
I've not seen that declared on any other that I've used, and wanted to see if anyone has knowledge/opinion on whether this is typical of all duster gas, or a cause for concern. Seeing the term 'petroleum' on there gives me pause...
If it's fine, I'm going to acquire some more =]
Any info appreciated.
