With all the good advice about cleaning my equipment, I finally tackled the task. I first wiped the outside of the P3 with a damp cloth to remove the external dust. I then took it to the bench with its anti-static mat and wrist strap, and opened it up. I couldn't find any dust inside, so I called it good and closed it up again.

I did the same with the K3. It actually had some detectable dust in the 100W amp section. I wiped that out with a damp rag and called it good.

My conclusion is that the radios are quite well dust sealed, even if there isn't a spec for this aspect of their performance.

Thanks to everyone who responded for your advice. I'm glad that heroic measures were not necessary.
