I soak mine in hot oxiclean solution, rinse them, dip it in star san solution, and then hang to dry. When I hang them I make sure that the tube is perfectly vertical without any bends which seems to help speed up the process. Also, the reason I dip them in star san is because it seems to evaporate faster that way. Plus the star san tends to evaporate "spot free". For that reason I always spray my beer glasses with it after washing them, and let them drip dry. It makes them crystal clear and aids in head retention.
