Ok well after blowing out what i can with a air gun i then completely wash the part in warm water and detergent, then rinse off with clean water then blow dry again. Wear saftey glasses when your blowing them off with compressed air because you will find when you shoot into holes it will spit beads back at you.
If its a bare steel part i dont want to go rusty then i just blow the part off whcih usually gets rid of any remaining beads anyway, and then rinse the part in solvent or brake cleaner then blow dry again.
