Place the jar in the water and let the wax heat up, you don't want to fully melt the wax because that will make a big mess. Using a knife you can loosen the wax around the edges. It tends to take 30 seconds to a minutes to do this.
Remove the jar from the heat you should be able to cut through the centre of the wax and it should pop out easily.
Now to remove to excess wax on the sides. If there isn't a lot of wax left some soap and water should remove it easily. If there's a lot fill the jar with boiling water from the kettle and leave for about a minute. After that the wax should wash away. You can use the knife again to remove any larger bits.
To remove the label on the bottom warm water and a knife should do the job. You can also use some soap to help lift the label.
If there is still some residue or glue from the label some nail polish remover and cotton pads works great.
Cover the cotton pad with nail polish remover and rub until the glue is removed.
This will help with removing those last little bits of wax. Finally give the jar one last rinse with warm water to remove any nail polish remover.
Now you're done! It is really easy to and should take around 10 minutes. These jars can make great storage jars. Some ways to use them are brush holders..
Or even as braclet storage! There are so many different things you can use this for even if its just general knick knacks.
I hope this post was helpful and if you try this please let me know in the comments. Do you love candles and do you reuse the jars?
