We are talking about very short duration of burst say 1/10 s to dislodge whatever dust there
The other thing with canned air of course is the force it delivers the air.
May be too high a pressure for the delicate electronics.
And FAR from the nozel anywhere's near the sensor.... like barely at body opening.
And at any rate you go back to my original post the WORST thing you can do is try to blow it off with breath (origal post replied to... "I huffed and Puffed) due to the high moisture content that can both cause damage and possibly glue the dust better or add more particulates.
