What You'll Learn

Freeze the candle jar overnight, then pop out the wax
If you want to remove candle wax from a glass jar, freezing the jar overnight and then popping out the wax is a great method. This method is simple, effective, and safe, and it allows you to remove wax from multiple candle jars simultaneously.
First, peel off any labels on the jar and use a sponge or paper towel to wipe away any soot inside. If there is adhesive residue, you can use store-bought or homemade adhesive remover. Next, place the candle jar in the freezer and leave it overnight. The wax will shrink and loosen from the glass, making it easier to remove.
After freezing, take the jar out of the freezer and turn it upside down. The frozen wax should pop right out. If it doesn't, use a spoon or butter knife to gently press down on one side of the wax to lift and loosen it. You can then shake the jar or tap it lightly on a surface to encourage the wax to come out. If the wax still doesn't come out, put the jar back in the freezer for another hour or two, as sometimes it may require a little more time to fully shrink and loosen.
Once you've removed the wax, you can clean the jar by dipping a paper towel in household cooking oil and wiping the inside of the jar. The oil will dissolve any remaining wax residue, which can then be wiped away. Finally, rinse the jar with warm water and a mild dish soap to remove any excess oil.

Use a butter knife to chip away large chunks of wax
Removing wax from candle jars is an easy process, and it allows you to reuse the jar for storage or as a decorative item. The first step is to chip away at the wax with a butter knife to remove large chunks. This mechanical method is simple and effective, but it requires a bit of elbow grease.
Firstly, assess the amount of wax left in the jar. If there is a significant amount, you will need to chip away the larger portions with a butter knife. Hold the jar steady with one hand and use the other hand to gently insert the butter knife between the wax and the glass. Gently twist the knife to create a slight gap between the wax and the jar, and then slowly work the knife around the edge of the wax, prying and chipping away as you go. Be careful not to scratch the glass with the knife. This process may take some time, and you may need to stop and adjust your grip to get a better angle.
If the wax is in smaller pieces, you can try using the knife to scoop it out, being mindful of your fingers and the glass. For stubborn chunks, you can try applying gentle leverage by placing the knife at the base of the wax and carefully pushing or twisting to loosen and lift it out. Always take care when handling sharp objects and be mindful of the broken wax pieces, ensuring they are safely disposed of or melted down for further use.
This method is a great starting point for removing wax, and it can be followed by other steps to ensure a thorough clean. For example, if there is a solid block of wax at the bottom, you can try soaking it in hot water to melt and lift it out. Alternatively, placing the jar in the freezer overnight will cause the wax to shrink, making it easier to pop out with a spoon or knife.

Place the jar upside down in the oven
To remove wax from a candle jar, one of the methods you can use is your oven. This method is best for glass jars without decoration. Start by preheating your oven to 180–200 degrees Fahrenheit. Then, line a rimmed baking pan or baking sheet with aluminum foil or one or two layers of parchment paper. Place the candle jar(s) upside down on the pan or sheet. Put the setup in the oven for 15 minutes or until the wax has melted and pooled on the foil.
It is important to stay close to the oven and keep an eye on the candle jar(s) in case of any waxy mishaps. Once the wax has melted, remove the pan or sheet from the oven and place it on a heat-safe surface. Using a towel, pot holder, or oven mitt, hold the jar and wipe the inside with a paper towel. Let the jar cool down and then wash it with soap and warm water. You can throw away the remaining wax with the foil.
This method can be used with multiple candle jars at once. However, make sure the jars are glass and do not have any decorations.

Soak the jar in hot water to melt the wax
Soaking a candle jar in hot water is an effective way to remove wax residue. This method is simple and direct, requiring only a few household items. First, boil some water in a kettle or pot. The amount of water boiled should be enough to fill the candle jar, leaving about an inch of space at the top.
Next, place the candle jar in the sink and fill the sink with warm water. Ensure the jar is open and that any labels have been removed, as the warm water will help release the label. Let the jar sit in the warm water for around 30 minutes. The hot water will melt the wax, causing it to float to the surface. It is important to note that soft wax, such as soy wax, may only require hot water that is not boiling.
After the wax has melted, carefully remove the jar from the sink and pour out the water. Be sure to stop the drain to prevent wax from clogging the pipes. Once the water has been discarded, the jar can be cleaned with soap and warm water, using a sponge or paper towel to wipe away any remaining wax residue or soot. If there is stubborn buildup, an adhesive remover, such as Goo Gone, can be used.
This method is an easy and effective way to remove wax from candle jars, leaving them clean and ready for reuse or storage.

Clean the jar's interior with a sponge or paper towel
Once you've removed the wax from your candle jar, you'll likely notice some soot buildup inside. This can be easily removed with a sponge or paper towel. If you're using a sponge, dampen it first before wiping down the interior of the jar. If there's a lot of soot, you may need to change out your sponge or paper towel as you go to ensure you're effectively lifting the soot rather than just spreading it around. Any remaining adhesive residue from the candle's label can be removed with store-bought or homemade Goo Gone.
If you're having trouble removing the wax from your candle jar, try freezing the spent candle overnight. The wax will shrink in the freezer, making it easier to pop out the next day. If it doesn't fall right out, use a butter knife or spoon to help loosen it for removal. You can also try placing the candle jar upside down in an oven preheated to 200 degrees Fahrenheit. Line a baking sheet or pan with aluminum foil and place the jar on top. Leave the jar in the oven for around 15 minutes or until the wax has melted and pooled at the bottom. Remove the jar from the oven using an oven mitt and allow it to cool completely before washing.
Alternatively, if there's only a small amount of wax left in the jar, you can try boiling some water in a kettle or pot and then pouring it into the jar. The hot water will melt the remaining wax, allowing you to easily wipe away the residue with a sponge or paper towel. Just be sure to use caution when handling the hot water and jar to avoid burns.
With a little time and effort, you can effectively clean the interior of your candle jar using simple tools like sponges, paper towels, and hot water.
