1) To clean resin from the bowl, gently scrape the bowl with a needle tool, toothpick or pipe reamer. Use a cotton swab with rubbing alcohol to remove remaining resin. Rinse and air dry.
2) Over a sink, put a pinch of salt and some rubbing alcohol into the pipe. Plug the pipe holes with fingers and shake so that the interior resin is dislodged. Repeat and rinse well with warm water. Air dry. You may also place pipe, alcohol and salt into a zip lock bag. Let soak 5 to 10 minutes, then plug holes while pipe is still in bag and shake vigorously. Rinse well with warm water and let air dry.
