Good or bad idea

However, the cans of "compressed air" contain a lot of other things besides air that you normally do not want in your camera equipment.
A "rocket blower" would be a better option.

(36,827 posts)There's a few problems using compressed air cans. Air from these cans comes out in a relatively high volume, which means you're going to build up a static charge which will attract dust. The air is also relatively cold and more so the longer you spray which will cause condensation and attract even more dust.
The best thing to use is a bulb type blower and if that doesn't work use a soft bristled brush designed for that purpose.

Fototech makes a good blower too.
I would never use canned air on my gear - besides the pressure bending the diaphragm leaves or worse, it's going to drive any dust deeper into the lens instead of extracting it, roughening up the mechanism or worse getting on the internal optics. Vacuuming is a much better option...I'm a little reckless (well, a lot...I cleaned the sensor on my D70 by shoving the hose in the lens mount hole) so I just use the upholstery brush attachment on a regular vac, but if you're picky you can get a specialized electronics vac on Amazon.
That being said, the Rocket alfredo mentioned above is useful as all getout to have around, it won't actually pull dust away like a vac but you can puff as delicately as you need to knock pesky grains off of sensors and whatnot. Or go really oldschool and get a camel hair brush..

I've never heard of anyone trying that. Good luck.
