8 tips for reusing old candle wax

Tealight candles burning
There are many ways to recycle your leftover wax.

Don’t you hate it when you burn a candle but there is still a lot of wax left at the bottom? It seems a waste to just throw it away. With these tips, you don’t have to. You won’t believe all the things you can do with your leftover wax.

First off, you will need to remove the wax from the candle-holders. If the wax is easy to remove, you can use a knife to cut around the edge. For hard-to-budge wax, you can boil a saucepan full of water and place the glass or metal jar in the water until the wax begins to melt, making it easier to dislodge. Be careful with glass jars and don’t leave them in the water long.

Make new candles

Buy a pack of candle wicks and melt your old, unused candle wax in a saucepan. Pour the melted wax into your leftover candle holders, making sure the wicks are placed inside. Voila! You now have a brand-new set of candles. When you melt the wax, you can add food colouring, herbs and other scents to create your own unique candle.

Melt the wax down enough so that it is warm to the touch and flexible. Push the wax around the edges of anything sharp and build on the wax as it cools.

Make aromatic wax melts

Collect your old, unused candle wax. When you have enough, melt your wax in a saucepan. Add food colouring, herbs, essential oils, or special candle scent oils. Just make sure you check that none of your materials are highly flammable. Pour the melted wax into small cupcake liners to give them shape. You can save them if you have a diffuser or place them around the house to keep your rooms smelling nice and fresh.
