Thanks guys!
It was pretty easy to clean; rinse, use brush for tight areas, and wipe dry. Most of it was dust bunnies from storage and dust from use. Only grime was on the rear axle, maybe I was leaking? I don't remember really bashing it. It was my first rc so I tried to go easy. I still remember letting my cousin drive it and he went straight under a parked car, well only the hood made it under. That crash broke the "air scoop" and I think another cousin rolled it and broke off the roll bar lamps. I can't remember how the body cracked.
