Waxing Creative: Repurpose Candles, Reuse Containers

how to empty a candle

Whether it's to reuse the jar or to recycle it, it's important to know how to empty a candle without damaging the container or the surface it's sitting on. There are several methods to remove wax from a candle jar, including freezing the candle, melting the wax with boiling water, using a double boiler, or placing the candle in the oven. Freezing the candle causes the wax to shrink and loosen, making it easier to remove in a large frozen lump. Melting the wax with boiling water will cause the wax to float to the top of the water, where it can be removed after cooling. Using a double boiler or placing the candle in the oven will melt the wax, which can then be poured out.

Freeze the candle

If you want to remove wax from a candle jar, freezing is a great method. It's safer and more convenient than melting wax, and you can remove wax from multiple candles at once.

Start by placing the candle jar in the freezer. Leave it for at least three to five hours, or preferably overnight for the best results. The colder the temperature, the better. Freezing the wax will cause it to harden, shrink, and loosen from the container.

Once the wax is frozen, take the container out of the freezer and flip it upside down. The lump of wax should pop right out. If it doesn't, use a butter knife or spoon to gently loosen the edges and lift out the wax. You can then scrape off any remaining wax residue and clean the container with dish soap and water.

If the wax is still stuck to the glass, simply place the candle back in the freezer for another hour or two.

This method works well with wide-mouth candles, and you can use it to remove wax from multiple candles simultaneously.

Use a hairdryer or heat gun

If you're looking to empty a candle jar, a hairdryer or heat gun can be an effective method. This approach is especially useful for targeting stubborn wax in specific areas at the bottom of the jar. Here's a step-by-step guide:

Prepare Your Work Area:

First, ensure your safety by wearing an oven mitt to protect your hands from the heat. It's important to work on a heat-safe surface to avoid any damage. You can place the candle jar on a dish towel or potholder to protect the surface underneath.

Using a Hairdryer or Heat Gun:

Now, you can begin melting the wax with the hairdryer or heat gun. Direct the hot air towards the areas with stubborn wax. The heat will melt the wax, making it easier to remove. Be cautious and patient during this process, as it may take some time for the wax to fully melt.

Remove the Wax:

Once the wax is melted, use paper towels to wipe away the excess. You can also use a spoon or butter knife to gently loosen and lift out larger chunks of wax. Be careful not to scratch the jar during this process.

Clean the Jar:

After removing the majority of the wax, clean the jar with dish soap and warm water. You may need to use a semi-abrasive sponge or scrub well to remove any remaining wax residue. Repeat this step if necessary until the jar is completely clean.

Additional Tips:

If you're dealing with softer candle wax, such as soy or coconut wax, consider using a lower heat setting on your hairdryer or heat gun. Additionally, be mindful that using a hairdryer or heat gun may not be the best method if you have multiple candles to empty at once, as it requires treating one area at a time.

Boil water and pour it into the candle

Boiling water is an effective method to remove wax from candle jars. This method works best with wide-mouth candles. Begin by placing your candle on a protected surface, such as a dish towel, potholder, or pan lined with tin foil to catch any overflow. Boil enough water to fill the candle jar, leaving an inch of space at the top. Carefully pour the hot water into the jar. The heat will cause the candle wax to melt and rise to the top. Once the water has completely cooled, the wax will solidify, making it easy to remove. Ensure your sink drain is stopped, then carefully strain the water and any candle remnants using a sink strainer. You may choose to save the wax for future projects or discard it. Be sure to remove all wax remnants from the sink before releasing the drain stopper, as wax can clog your drain.

Another variation of this method is the double boiler approach, which is better for those who want to maintain the integrity of the candle label. Place your candle into a large empty pot or bowl and pour the hot water into the container around the candle. Once the wax begins to soften around the edges, you can pop it out with a knife. This method may also cause water damage to the label.

You can also try submerging your candle in a sink or pot of hot water and dish soap for at least 10 minutes. If the label is not loose, you can add a tablespoon of white vinegar. This method should remove the label, but if there is any residue, try scrubbing with baking soda.

Use a butter knife or spoon to scrape wax

Using a butter knife or spoon to scrape wax is a straightforward method to empty a candle. It is also a safe method as it does not involve heat.

First, place your candle in the freezer for several hours or until it is frozen. The colder the temperature, the better. Freezing the wax doesn't just harden it, but also causes the wax to shrink and loosen. When you're done, you should be left with a large, frozen lump of wax at the bottom of the jar.

Next, take the candle out of the freezer. Using a butter knife or a spoon, slowly and gently poke at the edges of the wax to loosen the frozen lump from its container. If the wax remains stuck to the glass and refuses to loosen up, place the candle back in the freezer for another hour or two. Don't worry about over-freezing it! Once you've loosened up the edges enough, the lump of wax should be ready to come out.

If you are using a butter knife, be gentle and careful so as not to scratch the glass. If you are using a spoon, make sure it is made of a sturdy material that can withstand the cold temperature of the frozen wax.

This method works well for removing wax from multiple candles at once. It is also a good option if you want to save the wax and reuse it, as freezing does not alter the properties of the wax.

Clean the jar with soap and water

Once you have removed the wax from your candle jar, you can begin cleaning the jar with soap and water.

First, remove as much wax as possible with a butter knife or a spoon. You can also use a hairdryer or heat gun to spot-treat any stubborn areas. Next, place the jar on a protected surface, such as a dish towel, newspaper, or a pan lined with tin foil. Then, pour boiling water into the jar, leaving about an inch of space at the top. The water will melt the remaining wax, causing it to float to the surface. Allow the water to cool completely, which may take about an hour, and then remove the wax disk that has formed at the top. Pour out the water, being careful to use a sink strainer to catch any remaining wax bits. Finally, clean the jar with dish soap and hot water, using a semi-abrasive sponge to scrub away any remaining wax residue. You may need to repeat this process once or twice to ensure that all the wax residue is removed.

Alternatively, you can place the candle jar in the dishwasher and wash it with your other dishes. However, it is important to note that this method may not be as effective in removing stubborn wax residue.
