If the slides are in glassless mounts the film cleaner used carefully. If
in glass mounts use either lens cleaner or a cleaner made for spectacle
lenses again very carefully.

Never, ever, use canned air on film, lenses, screens or anything else
that is valuable. Not only can it spit out propellent if held at the
wrong angle but it can also spit out freezing gas.

Use a safe method like a Rocket blower.

It contains no propellent, is not flammable, not explosive, contains no
dangerous fumes, etc. Nothing but air comes out the nozzle.

Why do you think that you can't use canned air at work?

BTW, that Staticmaster brush used a strip of radioactive polynimum (or
how ever it is spelled). First problem is that it had a very short half
life and would loose its static repelling charge. Second problem -
remember that KGB agent that died in London recently?

Your response is so riddled with inaccuracies that I'm compelled to respond.
Canned air can also be very effective, and will not spit out propellant, or
freezng gas, or a stream of tiny monkeys, if you hold the can upright.

Nothing against Rocket blowers.

Canned air contains propellant, and some care must be taken to keep the can
upright, however it is not flammable, explosive, nor does it have dangerous
fumes. There is nothing like canned air for blowing dust out of complex
components and equipment. It does a great job at cleaning a keyboard, for
example, and I used it to good effect cleaning dust out of a microscope
lighting system.

Your guess is as good as mine. Possibly it's too expensive.

The half life is very short, about four months, so do not purchase one that
has been on the shelf for a significant length of time.

The polonium used in anti static products is encapsulated as tiny plastic
beads and will not be absorbed even if ingested, it is not a strip. While I
respect the decision of those who choose not to have radioactive materials
in their proximity, it is not considered a significant health risk.

Yes, he was 'blown away'...

First a poison-tipped umbrella, now a can of compressed air - these SMERSH
agents are tricky, huh?

I flick them hard with a finger a couple of times and then blow using
one of those rubber bulb syringes that come with ear wax removal kits.
The if there is still visible dust, scan with ICE active. If there is
still some defects on the finished scan, Use Polaroid Dust and Scratches
filter (either free standing or as a PS plugin). there are also other
dust "removal" software.

Don't use your mouth to blow them as this contains moisture and the
canned air sprays are relatively expensive and may shoot propellant.

Well, it *is* a strip, in some sense; those beads are in turn bonded or
embedded in a small strip that you can see.

Clever designers, using the half-life of the source of ionizing
radiation to make *sure* people bought a new brush frequently .
