Typically there is no cleaning ever done. I would NOT recommend attempting to clean the supercharger with anything while it is still on the car and WOULD recommend researching for the proper cleaner or the below will happen to the coating on your supercharger rotors and you'll strip the grease out of the bearings.
These rotors should be a uniform gray color, solidly coating of epoxy.
This was done with a soaking of over the counter TB cleaner.
