Pour boiling water into the candle jar and cover it. Let it sit overnight.
The wax will float to the top and harden into a neat cake. Remove the hardened wax. Reuse wax in a oil burner or dispose of wax in the bin.
If there's any remaining wax on the bottom, repeat with boiling water.
DO NOT wash any wax down the drain.
Wash with soap and now you can reuse your jar/glass!
