dont know why no one invests in a ultrasonic cleaner?
it cleans the inside and outside without even touching it.
i use it to clean my pipes,headers,hardware,crankcases,pistons,headbutt ons,sleeves rods,cranks,cooling heads,clutches,clutch bells,differentials,flywheels,carb parts,suspension parts,anything i can fit inside,i even stick my electric shaver heads in there
