I employ a little 2" paintbrush (unused of course!) to dust off the panels and remove the crap that lodges in the joints between consoles. It helps. But its the filthy dirty headsets that get me! We can't have personal headsets, so we get to enjoy having dandruff and hair ridden earmuffs caressing our noggins.
I've had a recurring problem with lip infections - cold sores - in exactly the spot where the boom mike sits. YUCK!!
Are you allowed personal headsets? How did you arrange this with your employers?
