Thanks for directions. I was lazy, spray the engine bay with Castrol Super Clean, wait few minutes then rinse it off with tap water from garden hose, after rinsed I let the hood up to have it air dry. If I was not so lazy on that day I would use the shopvac(blower) to dry.
Next time will try your method and hope that my engine will be as nice as yours.
