If you've ever wondered how to reuse old candle containers, we've created the ultimate guide that covers everything from removing old wax to great ideas for repurposing scented candle jars. If you are as addicted to candles as we are, then you will undoubtedly have a huge pile of burnt-out candles somewhere. Each candle has been fully enjoyed and only a small amount of wax remains in the bottom of the old jar. The first step to reusing the old scented candle jars called "home" is to remove all the old wax from them. There are many different ways to achieve this.

How To Clean Leftover Wax From Candle Jars?

The Freezer Method

Because candle wax becomes brittle when it is frozen, it can be easily removed from the container. First, place the old candle container in the freezer for a few hours. Once frozen, use a knife to gently pry out any remaining wax. Put some warm water on a paper towel and wipe off any remaining debris. This is a good way to use candles made from paraffin or beeswax.

Double boiler / Bain Marie method

For stubborn leftover wax, the double boiler method would be a good option. This method works by filling a bowl with boiling water and gently placing the candle jar in it for a few minutes. The heat from the boiling water will transfer through the sides of the container, melting the wax that remains inside. Once the wax has softened, carefully remove the jar from the water and pour out the melted wax. This can then be done by washing the jar with warm water and soap.

Wash off method

This is the easiest method and is suitable for candles made from low melting point waxes such as soy wax. First, use a sharp knife to remove as much of the remaining wax as possible. Then simply fill the container with soap and hot water from the tap, leave it for a minute and scrub the inside clean.

Things to keep in mind

Remove the wick holder

After removing all the wax, don't forget to remove the wick holder. If it gets stuck, simply insert a sharp knife underneath and pop it out. If it doesn't want to come out easily then a little boiling water will usually help.

Saving thin containers

To remove the wax from a thin container, try using a hairdryer to heat it up to loosen the wax before scraping it off with an old chopstick.

Keeping the old wax

It is often worth putting the old wax aside as you can use it for many projects. We'll be adding some ideas to the blog in the near future so make sure you sign up to our newsletter so you don't miss anything!

If you are concerned about fragile glass containers, we recommend using Wash & Go method - slower, but less likely to damage the container.

No drain

Do not pour wax that has melted in the water down the drain. It will cool and solidify and may eventually clog the pipe.

Do not overheat

You should be careful not to overheat the glass container. If the jar gets too hot, there is a risk that the glass will explode. In fact, freezing wax and pouring boiling water into the jar both carry a high risk of breaking the jar, so only use these methods if you are sure the container can handle it.

Don't microwave

Never use a microwave to melt the wax in an old candle jar. The wick holder that holds the candle wick in place is made of metal, which can not only damage your microwave but also cause a fire.
