These three steps work for cleaning glass, metal, and ceramic candle holders and accessories:
1. Remove excess wax by scraping and/or chipping it away. If there is a lot of wax you may find it helps to place it in the freezer for several hours first.
2. Soak in very hot water. For glass and ceramic accessories that have been in the freezer, allow them to return to room temperature before this step to avoid cracking
3. Wipe away any wax residue with a soft cloth or paper towel while still hot.
