Excellent advice above.
Just clean out the airway with alcohol-soaked pipe cleaners and wipe the bowl out with a couple of scrunched-up damp paper towels.
Some don't like bowl coatings. Most coatings give a neutral smoke, but some can be skanky. If you want to get rid of the coating, go carefully with some sandpaper.
Dry, fill-up and you're ready to go.
Enjoy your find.
