On our website https://thewaxcandles.com you can watch a lesson on how to clean candle jugs. If you have a candle in a pretty jar, you probably want to clean it up and reuse it for storage or decoration. However, you may find that removing all wax and residues is more difficult than you thought. The wax can be persistent, and smoke residue can usually be found on any used candle. You don't want wax leftovers to cover all your trinkets or anything else that you choose to keep in your candle jar.
