I don't know if it's a EU/US thing, but if I google DeoxIT I get tons of WD-40 results in front. Is it the same product? It's certainly cheaper.

Oh, HELL no! WD-40 is basically spray-on cutting oil, like 3-In-1 Oil or Liquid Wrench! Get that into a pot, and you're going to probably need to replace that pot soon after that. The only similarities to DeoxIT there is that both come in a spray-can...and that's IT.
Now, as for cleaning panels...I use a rather small shop-vac + a couple of tight-space brush attachments. Even with that vacuum, it still takes a brush to knock the dust up so the vacuum can deal with it. Note, however, that a vacuum will not deal with bloodstains...although, that will probably be of more concern to the 1st-gen Industrial and Power Electronics crowd.
