Customer asked why I keep a $6 roll of paper towels in my bag, and his reason for asking stuck with me
He runs a repair shop in Reno and says he quit using canned air on dusty towers after one blew a laptop fan apart on him. So now I wipe down every intake before I open anything, and I'm wondering if the canned air habit is worth keeping at all.
Did the shop owner say if he ever went back to canned air after that? I'm curious if he just swears it off completely or still uses it on stuff that can't get wiped down.
