i see many references to canned/compressed air that users here use to clean dust off their discs.
what is this exactly? what exactly is in the can? is it 100% air?
the only “Dust Cleaner” i could find here in an Office Depot store was “Dr. Byte Dust Cleaner”
the text in the pics in the above URL says “compressed air for cleaning computers. good for keyboards and computer surroundings”.
on the can itself it says it contains Butane and Propane (sp?)
if i use it on a disc it leaves a residue which slowly evaporates. or maybe not? something evaporates but maybe some junk remains.
also, what’s “duster” ? (mentioned a few times lately).
