The Best 5 Ways To Clean Your Candle Jar

It's both a sad and exciting time when your candle has nearly burned all its wax. Sad because you are nearing the end of its lovely scent. Exciting because it's time to get another!

If you've bought a candle in a jar or tin, you may find there's always that little bit of wax left over. This is completely normal; in fact, we recommend only burning your candle until 1/4" is remaining. 

You probably won’t be able to light the candle when it's in this condition. You may have tried numerous times, to try to get the most of your candle.

Now if you get fed up of trying to light it, don’t just throw away the candle jar with the remaining wax. Not only is that not environmentally friendly, but it means you definitely won’t get your money’s worth!

Some candle jars and tins are beautifully crafted and can be used in a variety of ways throughout your home, so it's a shame to just throw them away! You can give them a new lease of life by following our tips below.

5 Ways To Remove Left Over Wax From Candle Jars

These 4 methods will leave you with a shiny new container free of left-over candle wax.

  1. Freeze, Scrape & Wash
  2. Add Boiling Water
  3. Create A Doubler Boiler
  4. Use A Microwave Or Oven

You don't need any special equipment or gear. you'll find everything you need is in your kitchen.

1. Freeze, Scrape & Wash

This approach is very easy to do although it could turn out a bit messy.

Step 1: Stick your candle jar in the freezer for a couple of hours. This will cause the wax to contract and shrink making it a lot easier to remove.

Step 2: Use a butter knife or even a spoon to scrape out the left-over wax. If you have left it long enough in the freezer it should pop right out. 

This is the bit that could get a bit messy, so be sure to do this over the sink or on some tissue paper so you have an easy clean up.

Step 3: This is the easy part. The last bit is to clean the candle jar out using some warm soapy water. Make sure to remove any remaining bits. You should end up with a shiny new container!

2. Add Boiling Water

This method might be slightly quicker than the above. Make sure to take care when you’re dealing with boiling water.  This should melt the wax and float up to the top of the jar.

Step 1: Line up your candle jars in a suitable area. Somewhere you don’t mind getting a bit wet. You can protect the surface area with a towel or newspaper.

Step 2: Boil your kettle. 

Step 3: Pour the boiling water into your candle jars. Be careful at this step. Don't pick up the candle jars with your bare hands.

Step 4: Leave this to sit in for 2-5 mins, until it has cooled and you can see wax at the top.

Step 5: Pour out the water, carefully! Don't pour the wax down the drain. Use a strainer to catch excess wax. You can then re-use or bin this.

Step 6: Give the jar a quick clean and wipe to remove any left-over wax. Swill it out with cold water to cool down the jar.

Step 7: If the wick tab is still left behind remove it at this point. 

3.  Create A Doubler Boiler 

For this method you don't actually need a double boiler, we will be recreating the concept of one. This will involve resting the candle jar inside a bigger container of boiling water. 

The boiling water will soften the remaining wax inside the candle jar and allow for an easy removal.

Again, take care with this one as its dealing with boiling water. You'll need a large heat proof bowl, or a large enough saucepan.

Step 1: Remove as much excess candle wax as you can with a butter knife and put the kettle on.

Step 2: Once you've removed as much as you can, add the boiling water into your chosen container. 

Step 3: Once the water is in the container carefully place your candle jar into the water. Let this sit for a few minutes.

Step 4: Carefully remove the candle jar from the container. At this point the glass will be hot so do not touch this directly. You should be able to remove the wax with a butter knife or a spoon very easily.

Step 5: Once you've removed as much as you can, wash out the candle jar with soap and water for one final clean.

4.  Use Your Microwave 

Before you consider using this method you need to ensure your jar is microwaveable.  

Do not microwave coloured glass or glass with visible air pockets. Should you have any doubts, choose one of the above methods.

This method also uses heat to melt the wax slightly making it easier to remove.

Step 1: Using a butter knife remove as much excess wax as you can. Remove the wick collar (the metal end of the wick).  

Step 2: If you've scraped away as much as you can, put the jar in microwave for about 20 seconds. 

Step 3: Wipe away any melted wax with a paper towel. Repeat this step as many times as required.

Step 4: Once you’re happy all the wax is gone, to finish, wash with hot water and soap. 

5. Use Your Oven

If you have a few candle jars that need cleaning, this is the method for you.

Step 1: Scrape as much wax out as you can with a butter knife. Set your oven to 180 degrees Celsius.

Step 2: Line a baking tray with tin foil or baking paper. Use 2 lines if you want to be extra careful.

Step 3: Place your candle jars upside down on the baking tray and put the tray in the oven for 15 minutes.

Step 4:  Remove the pan and place on a heat-safe surface. Hold the container using a towel or pot holder and wipe the inside with a paper towel. 

Step 5: Let the container cool and then clean with soap and water. 

Happy cleaning!
