Does anyone have any experience cleaning the engine bay beyond a wipe with a wet towel? I wipe down the plastic covers every now and then, but the rest of the engine hasn't been cleaned since getting the car. Aside from cover the electrical and HV components (the majority of the right side) with a plastic bag, anything else that needs to be done? My main concern is the plastic cover at the bottom of the engine, would that allow for enough water drainage?
