A well meant gift of an "aerosol duster" has me wondering. Are these things safe for cameras? Does the propellant leave residues? Is the blast too powerful, or even capable of doing damage? My inclination is to stay with the conventional puffer. Advice welcome

Hi Brian,

I haven't used one of these cans for a long time now (er, years!), so some of what I say may be wrong but from what I remember when I used them last:-

Does the propellant leave residues? - The can stated that it should be used upright and I'm sure "something other than air" did come out once when I used it on it's side.

Is the blast too powerful or even capable of doing damage? - It could be, there were warnings about where you pointed the nozzle as it could damage sensitive/moving parts, although some of the newer ones that I have seen use a trigger mechanism that gives better control of the release of air.

So, if you're careful where and how you use it, there should be no problem, but as you say, I have stayed with with my Giottos Rocket blower.

Hope it helps.........

I've never used one for my own gear, but isnt that what they use to clean lenses and sensors in second hand gear shops?

Never shake the cans before use as this will cause the air to become extremely chilled and could cause problems like cracking glass.

I personally would not use them on a sensor, wet wipes all the way.
