How to Re-Use Your Jar
Pop your candle jar in the oven at its lowest setting until any remaining wax melts. Carefully remove the jar from the oven to pour the wax into the trash, pop out the wick holder using a spoon or fork, and wipe the insides of the jar clean with a cloth. Hand wash, rinse, and dry.
Place your candle into the freezer until the remaining wax hardens, then carefully chip out and throw away the wax using a spoon, being sure to remove the wick holder as well. Use a cloth to wipe the insides of the jar clean, hand wash, rinse, and dry.
If you’re reusing your candle jar as a planter, add some small rocks for drainage to the bottom before adding soil.
