do rocket blowers go bad?

i swear my large rocket blower which is probably about two years old made the sensors on both my cameras much dirtier when i blew them off today. anyone experience this before?

I think it's time to get out and shoot...

(actually, if the rubber on the inside started decomposing then it could be blowing particles out... So you could be on to something)

I haven't used my rocket blower in ages. I never use it since there's potential to blow particles onto the sensor. I just use the good old wet cleaning method and dust aid.

what kind of gas have you been putting into it?

i haven't used mine in awhile either. both of my cameras were just serviced and the sensors were cleaned.

you need a kick in the pants to get you going or what ?

If it's old, I suppose the internal baffle that's supposed to keep it from sucking air in the front could go bad. That would probably mean you're just blowing the same air in and out instead of getting "clean" air in the back.

Try it and see. Give it a squeeze and see if there's suction at the front when you release it (there shouldn't be)

no, there's no suction. both cameras were recently serviced by canon. maybe they filled them with dust...

they do a very lousy job of cleaning sensors, btw.

okay. the fins on my large rocket blower have this white powdery stuff beginning to form. my smaller rocket blower doesn't have it.

i pulled the plug from the large blower and there is white powdery stuff inside. my other rocket blower is perfectly clean inside.

so, yeah, rocket blowers do go bad and the clue is the fins will start turning white.

I love a mystery!

Ed,

It's probably the break down of the rubber they used in making the device.
