Yes: you just carefully unscrew the plastic covers, wash them in the shower and dry them thoroughly (they contact metal and can trap water leading to rust) and while that drying is happening, vaccum the blades and interior.

Carefully reassemble. Note that the screws will bottom out and just need to be snug, not torqued down. Torque and you will strip the holes in the sheet metal

I would imagine you could wipe down the blades and interior of the case with an antistatic wipe, but I haven't really investigated that route. That might inhibit future buildup.
