There are several ways to remove candles from glass jars. One way is to place the jar in the freezer for a few hours or overnight, allowing the wax to shrink and easily pop out. Another method is to use a hairdryer or heat gun on its lowest setting to melt the wax, which can then be wiped away with a paper towel or cloth. A third option is to fill a pot or saucepan with water, place the candle jar inside, and bring the water to a boil. Once the wax has softened, it can be removed with a spoon or knife. Finally, if there is not too much wax left in the jar, simply freezing the jar and then flipping it upside down will cause the wax to fall out.
Removing Candle Wax from Glass Jars
| Characteristics | Values |
|---|---|
| Freezer method | Place the candle jar in the freezer for a few hours or overnight. Once the wax is frozen, it will be easier to pop out or chip out using a butter knife or wooden popsicle stick. |
| Boiling water method | Fill a pot or saucepan with water and place the candle jar inside. Bring the water to a boil, then remove the jar and pour out the melted wax. Alternatively, pour boiling water directly into the jar to soften the wax, then scoop it out with a spoon or butter knife. |
| Oven method | Preheat the oven to 150-200 degrees Fahrenheit. Place the candle upside down on a baking pan lined with aluminum foil. The wax will melt and pool on the foil, which can then be discarded. |
| Hairdryer or heat gun method | Use a hairdryer or heat gun on a low setting to soften the wax. Target the wax with heat until it becomes soft or melts, then wipe away with a paper towel or cloth. |
| Double boiler method | Use a double boiler to melt the wax slowly, then pour it out and wipe the jar clean with paper towels or isopropyl alcohol. |
| Spoon method | For softer wax types like soy, simply use a spoon to remove the wax. |

What You'll Learn

Using a hairdryer or heat gun
First, place the jar on a flat, heat-resistant surface, such as a wooden cutting board. Avoid using plastic, as it may soften and become damaged. If your jar has any adornments, such as glitter, sequins, or stickers, try a different cleaning option, as direct heat may damage the decorations or cause them to come off.
Next, turn on your hairdryer or heat gun to the lowest setting. Heat the sides and bottom of the jar until the wax becomes soft and starts to melt. Be careful not to overheat the jar, as this can cause cracking or other damage.
Once the wax is soft, use a butter knife or spoon to gently loosen and remove it from the jar. You can also wipe away the melted wax with a paper towel or cloth. Repeat this process as needed until all the wax is removed.
After removing the wax, you may need to clean the jar to remove any residual wax, soot, or other stains. Wash the jar with warm water and dish soap, or a mixture of baking soda and dish soap, to remove any remaining wax and soot. You can also use natural, non-toxic cleaning products like Magic Eraser to scrub away stubborn residue. Finally, dry the jar with a paper towel or let it air dry.

Freezing the wax
Freezing wax is a highly recommended method for removing candle wax from glass jars. Candle wax hardens and shrinks when it gets cold, so freezing is often enough to make the leftover candle wax pop loose.
To freeze the wax, place the candle jar in the freezer for a few hours or overnight. The National Candle Association recommends freezing for an hour or so, allowing the wax to shrink and easily pop out. After freezing, remove the jar from the freezer. Turn the jar upside down and the candle wax will fall right out. If it doesn't, gently chip at the wax with a butter knife, wooden popsicle stick, or similar tool. Avoid using sharp items that might damage or break the glass.
If there is leftover wax along the insides of the container, try running hot water over the exterior of the candle holder. Make sure the glass is at room temperature before running it under hot water. Then, use a cloth or paper towel to wipe away the melted wax. You can also use a hair dryer or heat gun on its lowest setting to target the wax and make it soft and melty. Wipe away the melted wax with a paper towel or cloth. Repeat the process until all the wax is removed.
Once you have removed all the wax, wash the jar with warm water and dish soap to remove any remaining flakes of wax or oily residue. You can also use an adhesive remover, such as Goo Gone, for stubborn buildup.

Boiling water
- Fill a saucepan or pot with water and bring it to a boil. You can also use a kettle to boil water. Make sure the water level is high enough to cover the wax residue in the jar.
- Place the jar on a heat-safe surface, such as a cutting board or a hot pad, to protect your countertop from the heat.
- Once the water is boiling, carefully pour a small amount of boiling water into the jar, covering the wax residue. You can also lower the jar into the saucepan of boiling water, holding it there for 1-2 minutes. Be cautious when handling boiling water to avoid burns.
- Allow the wax to melt and rise to the top of the jar. The wax will soften and separate from the glass.
- Let the jar cool for several hours. Keep it out of the reach of children and pets during this time.
- Once the wax has cooled and hardened, pop it out of the jar. You may need to use a rubber spatula, spoon, or butter knife to remove the wax gently.
- If there is still wax residue in the jar, repeat the process.
- Finally, wash the jar with soap and warm water to remove any remaining wax or oily residue.
Some additional tips to consider:
- Always ensure the glass jar is at room temperature before pouring in boiling water to avoid the risk of shattering due to sudden temperature changes.
- For softer candle wax, such as soy or coconut, boiling water may be too intense. Instead, you can try the double boiler method, where you place the jar in a small bowl and set it on top of a container with hot water.
- If you want to reuse the wax, you can pour it into a container and let it harden.

Using a double boiler
To begin, fill a large pot or container with hot water. Place your candle jar inside, ensuring that the water level is no more than three-quarters full. If you are using a smaller bowl for your candle, simply set it on top of the container with hot water. The warm water will gradually heat the jar, causing the wax to soften and melt.
As the wax softens, it will begin to loosen from the sides of the jar. You can test if the wax is soft enough by poking it gently with a spoon or knife. Once the wax is soft, it can easily be removed in several large pieces. Use a butter knife, wooden popsicle stick, or similar tool to gently chip at the wax. Avoid using sharp objects that could damage or break the glass.
If there is any remaining wax or residue, simply pour hot water into the jar to soften and remove it. This process may need to be repeated for larger vessels or particularly stubborn wax. Overall, the double boiler method is a safe and effective way to remove candles from glass jars, leaving you with a clean jar ready for repurposing.

Soaking and washing
To remove candle wax from a glass jar, there are several methods you can try. One popular method is to freeze the jar, which causes the wax to shrink and makes it easier to remove. Place the jar in the freezer for a few hours or overnight, then remove it and turn it upside down. The wax should fall right out, but if it doesn't, you can gently chip at it with a butter knife, wooden popsicle stick, or similar tool. Avoid using sharp objects that could damage the glass.
Another method is to use hot water to melt the wax. Boil a pot of water and place the jar on a flat, heat-resistant surface, such as a wooden cutting board. Fill the jar with hot water and let it sit for a few minutes. The hot water will melt the wax, allowing you to pour it out or wipe it away with a paper towel or cloth. You can also use a combination of these methods by freezing the jar first and then pouring hot water into it to melt any remaining wax.
If you have access to a hairdryer or heat gun, you can use it to soften the wax for removal. Turn the hairdryer or heat gun to the lowest setting and target the wax until it becomes soft and starts to melt. Wipe away the melted wax with a paper towel or cloth, repeating as needed until all the wax is removed.
Once you have removed the majority of the wax, you can wash the jar with warm water and dish soap to remove any remaining flakes of wax or oily residue. Be sure to rinse the jar thoroughly and wipe it clean before reusing or recycling it.
