They are great for storing make-up brushes, q-tips and cotton rounds. Alternatively, you can reuse an empty candle jar as a vase for displaying cut flowers as part of your dining table decor ideas. If your candle jar is large enough it can make for a pretty drinks tumbler, too – great for garden party ideas. Some companies even purposefully design their candle jars to be reused afterwards, for example Keep Candles (opens in new tab) have bowls, egg cups and mugs that are all designed to become kitchenware once the candle has burnt out. Also Paddywax’s beautiful glass candle jars transform into the prettiest tumblers and vases once cleaned.

What can you do with old candle wax?

Once you’ve found out how to get candle wax out of a jar, you can remelt the wax in a pan and then pour around a new wick and leave to set. Once it has set, you can then light the wick and enjoy your new candle.
