A customer in Portland told me to stop using canned air on shutter blades
He said the propellant can leave a residue that gums things up over time, and now I just use a blower brush. Anyone else make that switch?

The residue thing is real, but I'm more worried about the cold. That sudden blast of freezing air on warm metal can cause condensation inside the shutter box. You're basically inviting moisture to sit on the springs and pins. A blower brush moves air without that temperature shock, which seems safer for the tiny moving parts in the long run.
