Is cleaning this area necessary and how

Here are pics of area I can not figure out how to clean. I am afraid to accidentally disconnect something by reaching in there. Should I be concerned.

Normal accumulation for us laser nerds. I have used my shopvac with a brush attachment in there - once. Nothing to be alarmed about, it is essentially ash. Yeah, I had no idea a laser was such a messy machine.

It’s only an accumulation of the finest particulate, smoke. It comes off with the lightest touch. It would only be problematic if an electrolyte were introduced. Get it wet and all bets are off.
