The Vapor Stone can be easily cleaned in a couple of ways. Before all else, you must remove the stone from a pipe or attachment by (gently but firmly) striking the stone face down on the palm of your hand, or any soft surface. The first way (and the most recommended method) is to soak the stone in warm Dark Crystal Cleaner™ or isopropyl alcohol for 1-2 hours. To dry you lightly pat it on a dry paper towel and let sit in a well ventilated area for at least 60 minutes. The second way (less suggested method) is by holding the stone with long metal tongs, and torching with a large butane flame until glowing orange. Although both methods work, we highly suggest the first method, due to the fact it keeps the stone more durable and long-lasting.
