In particular: I'd be cautious about using compressed air to clean out
electronic equipment that's been stored in sheds, barns, or other
locations where there might be rodent activity. I've seen some pretty
grotty equipment donated to our ham club, which I thought might well
have been peed or pooped upon by rats and/or mice.

Hantavirus is no joke.

A vacuum, particularly one with a HEPA filter, would be safer than
compressed air (either indoors or outdoors).

**Of course. And MUCH safer for the equipment.


How do you get the cat hair out of the CPU heat sink underneath the fan?

Since de fluxing solvents were banned to protect the ozone layer, most
electronics is cleaned with water - sometimes its an option, sometimes it
isn't.

Dish wash detergent works great, but they thicken it with salt - so make
sure you rinse it all out.
