How To Remove Wax From Candle Jar?

Candle lovers, we've all been there - you use more wax to wear out your expensive candle, but the wick life gets shorter and you get stuck with an unusable clump in the bottom of the jar. If you tend to burn through your favorite scented candles quickly, throwing away a pretty glass jar feels like too much of a waste, but burning a candle with more than a half-inch wax point can damage the container and the surface it sits on.


But don't worry: it's possible to breathe new life into that clunky wax packet container. We've put together some effective ways to clean candle jars so you can repurpose those containers for storage, decoration, or even a home for new candles. The best part? You don't need any special equipment. Any remaining traces of candles can be washed off with detergent - and when you're done, you should have a clean candle jar ready to be repurposed.


1. Microwave

Fill the candle with water and microwave it for one and a half minutes, up to two minutes. This will cause the wax to melt and rise to the surface of the water. Allow the glass and wax to cool, then quickly remove the remaining wax with a spoon or butter knife. IMPORTANT: Keep an eye on the candles while they are in the microwave as some wicks have metal wick holders that may pose a fire hazard.

2. Refrigerator

Probably the easiest and cleanest method on this list, this trick only works if you don't have too much wax (about an inch and a half). The wax will shrink when frozen, separating it from the walls of the container. After placing the candle in the refrigerator overnight, simply turn it upside down and scrape off the wax with a spoon or butter knife.

3. Boiling water

This method works best for wide mouth candles. Add boiling water to the candle - leaving an inch of space at the top - and let it rest. (Be sure to protect the surface where you place the candle, as it will be very hot.) You will see the wax rise to the top, similar to the microwave method, but at a slower rate. Finally filter the water (be careful not to pour the wax down the drain as it will clog) and remove the wax separately.

4. Double boiler

The microwave may be too strong for softer candles such as soy and coconut, so the double boiler method may be better. Place the candle in a large empty pot or bowl and pour hot water into the container around the candle. The wax will start to soften around the edges and pop out easily with a knife.


5. Oven

This method works well if you are working with multiple candles at the same time. First preheat the oven to 150 to 200 degrees Fahrenheit. Place the candles upside down on a baking sheet of aluminum foil. Keep within sight of the oven if any wax accidents occur, but if all goes well, the wax should steadily melt and collect on the foil within 15 minutes. Carefully remove the pan from the oven and then use an oven mitt to remove the glass from the pan. Once the remaining wax has dried on the baking sheet, you can remove it from the foil for future use or throw it away.


6. Heat gun

If you have a heat gun in your house, you’re probably already a DIY pro and don’t need much advice. But in case you weren’t aware, a heat gun (or alternatively, a hairdryer) is a great way to melt the remaining wax inside a candle. Just be careful not to burn the tag and make sure the candle is on a safe, heat-proof surface. When it is liquefied, you can use a paper towel to remove the excess wax.
