Mine looked like shit inside, and I bet yours do to.
I had some TPU85 tangled up in the gears, requiring a disassembly, so I figured I’d give it a proper clean while I already had it taken apart.

I had the extruder in my Qidi apart just last night because I had the tip of a piece of ABS snap off inside during a filament change. I found a bunch of dust presumably from various instances of filament grinding from the last few months, probably due to e.g. running the hotend at the wrong temperature for the filament due to being a dummy. It happens occasionally.
It’s not too tough to access on my machine but one of these years I will remember that you need to drop the heater block assembly out first, and then remove the gear cover. Just… not this time.
