I finally stopped using canned air on client PCs after a guy in Denver showed me his vacuum setup
I always figured vacuums were too risky with static, but he ran a static-safe one at a shop on Colfax and I watched it pull 3 years of dust out of a heatsink in about 20 seconds. Now my canned air sits in the truck and I'm wondering if anyone else made this switch or if I'm about to fry a board someday.
