Whether you're looking to repurpose your candle jar or create a new candle, removing leftover wax is a necessary step. The melting point of wax varies depending on its type, with softer waxes like soy and coconut waxes melting more easily than beeswax and palm. To remove softer waxes, the double boiler method is recommended, while placing candles in the freezer is ideal for harder waxes. Other methods include using a hairdryer, oven, or microwave. Once the wax is removed, it's important to clean the jar with soap and water before reusing it for storage, as a vase, or even a cocktail glass. Leftover wax can be reused to create new candles or wax melts.

What You'll Learn

Use the freezer method
Freezing is an effective way to remove wax from candle jars. This method is best for candles at the end of their life, with only about an inch of wax left.
To use the freezer method, place your candle in the freezer for a few hours. Leaving it overnight is ideal. Since wax shrinks when it freezes, it will separate from the edge of the jar. This makes it easy to pop out with a knife. If the wax doesn't come out easily, leave it in the freezer for a little longer and try again.
The freezer method is particularly useful for candles with thick wax up the sides. It is also a good option if you want to keep the label on your candle, as other methods may cause water damage.
Once the wax is removed, you can repurpose the jar as a vase, a catchall, or even a cocktail glass. You can also use it to store hygiene or makeup items, pens, or other small items.
It's important to note that the freezer method may require more time for larger vessels, as they will need to be in the freezer for longer than small votive candles.

Try the oven method
If you have multiple candles to melt at once, the oven method is a good option. Preheat your oven to between 150 and 200 degrees Fahrenheit. Place your candles upside down on a sheet of aluminum foil on a baking pan. Stay close to the oven in case of spillages, but if all goes well, the wax should melt and pool on the foil within 12 to 15 minutes.
Carefully remove the pan from the oven and take the glasses off the pan using an oven mitt. Once the leftover wax has dried, you can remove it from the foil and reuse it to make new candles or use it in wax melt warmers.
If you have less than a quarter of an inch of candle wax left, you can keep the candle right-side up and melt the wax. You can also use a heat gun or a hairdryer to melt the wax, but be careful not to wear any rubber or plastic gloves as they can melt.
Leftover candle wax can be used to make new candles, or you can use it in wax melt warmers. You can also use the empty candle jars for storage, as a vase, or as a cocktail glass.

Boil water and pour it into the candle jar
Boiling water is a great way to clean out your candle jars and prepare them for reuse. It's a quick and efficient method that will leave your jars sparkling and ready for their next purpose. Here's a step-by-step guide to help you get started:
Step 1: Boil Water
Start by boiling some water in a kettle or a pot on the stove. You'll need enough water to fill your candle jar, leaving about an inch of space at the top. This extra space is important to prevent the hot water from overflowing when you pour it into the jar.
Step 2: Prepare the Candle Jar
Before you pour the boiling water, make sure your candle jar is ready. If there is a wick remaining in the jar, try to remove it beforehand. The hot water will help loosen any remaining wax, but removing as much of the wick as possible first will make the process easier and reduce the risk of injury.
Step 3: Pour the Boiling Water
Carefully pour the boiling water into the candle jar. Take caution during this step to avoid spilling or splashing the hot water on yourself. Fill the jar to just below the rim, leaving that important inch of space.
Step 4: Observe the Lava Lamp Effect
As you wait for the wax to melt, you'll be treated to a fascinating display. The hot water will cause the wax to melt and rise to the top, creating a lava lamp-like effect. This process may take a few minutes, so sit back and enjoy the show!
Step 5: Scoop Out the Wax
Once the wax has risen to the top and cooled down, it's time to remove it. Use a spoon to gently scoop out the solidified wax. Be patient during this step, as it may take a while for the wax to fully solidify. You might need to break the wax into smaller pieces to make removal easier.
Step 6: Clean and Reuse the Jar
After removing the wax, your jar may still have some residue or adhesive labels. Give it a good wash with hot water and soap to ensure it's completely clean. Now, your jar is ready for its new life! You can use it for storage, as a vase, or get creative with other DIY projects.
Remember, always exercise caution when working with boiling water and handle your candle jar with care to prevent burns or injuries. Enjoy the process of transforming your old candle jars into something new and useful!

Use a hairdryer or heat gun
If you have a heat gun or a hairdryer at home, you can use it to melt the remaining wax inside a candle. This method is ideal for when you have multiple candles to handle at once.
First, preheat your oven to between 150 and 200 degrees Fahrenheit. Place your candle(s) upside down on a sheet of aluminium foil on a baking pan. Stay close to the oven as wax may overflow and drip inside your oven. If all goes well, the wax should melt and pool on the foil within 15 minutes.
Remove the pan from the oven and take the glasses off the pan using an oven mitt. Once the leftover wax has dried, you can remove it from the aluminium foil. You can either throw it out or use it to make new candles.
If you have less than 1/4 inch of candle wax left, you can keep the candle right-side up and melt the wax. Be sure to wear an oven mitt to protect your hands and make sure you're working on a heat-safe surface.

Clean the jar with soap and water
Once you have removed the wax from your candle jar, you might still have some residue to deal with. If you've used any of the melting methods, you'll need to remove the water from your jar. Be sure to strain the water to get rid of any small wax bits and never pour wax down the drain—it can create a clog.
Now, you can begin to clean the jar with soap and water. First, scrape out as much wax as you can with a butter knife or spoon. If you still have small bits of wax at the bottom of your container, you can pop it in the microwave for about 30 seconds. Be sure you have a microwave-safe jar before doing this. Afterward, you should be able to simply wipe away any waxy bits with a paper towel, rather than having to scrape them with a knife.
Next, you can begin to clean the jar with soap and water. Fill the jar with hot water and a small amount of dish soap, then use a paper towel or microfibre cloth to clean the inside of the jar. If you have any stubborn stickers or adhesive residue, you can use a paper towel soaked in rubbing alcohol to scrub the remaining adhesives off the container.
Finally, rinse the jar with clean water and dry it thoroughly. Now your jar is ready to be reused!
