cleaning out accumulated "crud" is a damn good idea, since, as you say,
some of it may well be (semi)conductive.

Even if it's inert, it'll have a negative impact 'cause it's acting as a
blanket, keeping components hotter than they would be if running in
"free air" conditions.

Just make sure you know where the high-voltage connector is, and how
to discharge it, these things can hold a lethal charge long after you
unplug them... IIRC you want to clean around the high-voltage power
supply, lead, and tube connector with isopropyl.

If you have a source of compressed air, it's a good idea to blow out
all the dust (outdoors, of course). That way, you will get all the
dirt in the nooks and crannies.

Which is typically really all that is needed.
