While others speak highly of using a rocket blower to get dust off
their sensors, I've had nothing but mixed to bad results with anything
but wet cleaning. Here's one recent experience:

I have found it is always best to blow out the chamber first, then brush
with a chamber brush, and blow again before exposing the sensor.
A few puffs with the "rocket" and most loose dust will be gone.

How about using some sort of small vacuum cleaner in conjunction with the
blower? It seems to me no matter how you blow out the chamber, whether the
mirror is up or down, you're likely to be mostly just moving the dust around
unless you're using something to draw it out while it's circulating.

I don't have any such device in mind, but there must be something out there.


There are small brush/vacuum devices, operated on double AA cells
small enough with enough draw to pull disturbed dust out of the
chamber as you blow with compressed gas.


These devices are found in computer stores, and may be ordered on
line from TigerDirect and similar. They're sold as keyboard vacuums.

Low cost. Not big draw, but enough for this application.
