Now that's the opposite of what the sensor brush people claim on
their website. Their procedure includes blowing clean canned air
through the bristles of the brush prior to applying it to the sensor.
They claim that this imparts a static charge to the bristles and
helps pick up the dust. Frankly I would be surprised if a brush
didn't pick up particles the size that we are talking about. I blow
out the brush with canned air prior to using it anyway, as it seems
like a fairly good way to ensure that the brush is reasonably clean
at the moment of use.
I asked Godfrey that particular question because he has the real
sensor brush brush which is more longhaired than the cosmetics brush
I'm using, which is fairly stubby, not the sort of thing that would
show a static charge very well. the next time I get to a decent art
supply. I'll probably grab a couple of brushes to play around with.
What sort of anti-static brush do you have that's that small?

Do you buy that static charging business, by the way? I swear that at
least one time for me the cleaning process was more analogous to
sweeping everything into a pile, and then picking it up.
The CCD doesn't charge and attract dust but sweeping the polymer filter over
the sensor with a non-conductive brush and creating a static charge may, hence
I use an anti-static brush to sweep my sensor.
