There are many ways to clean out candle jars to prepare them for repurposing. The most common method involves pouring boiling water into the jar, which melts the wax and causes it to float to the surface. After cooling, the wax can be removed, and the jar can be washed with soap and water. Alternatively, the jar can be placed upside down in the oven at a low temperature, causing the wax to melt and pool on a baking sheet. The jar can then be removed and cleaned. Another method is to place the jar in the freezer, which will cause the wax to shrink and become easier to remove in a large chunk.

What You'll Learn
Use boiling water
Using boiling water is an efficient and eco-friendly method to empty a candle jar. It saves you from potentially damaging the jar with scrapers and allows you to repurpose the jar for other uses, such as storage or decoration.
Step 1: Prepare the Candle Jar
Place the candle jar on a protective surface, such as a dish towel or a potholder, to prevent any damage to your work surface from the boiling water. If the jar has a lid, make sure to remove it before proceeding to the next step.
Step 2: Boil Water
Boil enough water to fill the candle jar. It is recommended to leave an inch or less of space at the top of the jar to avoid overflow. Be sure to use oven mitts or a towel to protect your hands when handling the boiling water.
Step 3: Pour the Boiling Water
Carefully pour the boiling water into the candle jar. The hot water will melt the residual wax, causing it to float to the surface. Fill the jar almost to the top with boiling water.
Step 4: Let it Sit
Allow the jar to sit for several minutes or about an hour until the water cools and the wax solidifies and floats to the top.
Step 5: Remove the Solidified Wax
Once the wax has solidified, you can easily remove it with your fingers or a spoon. If there is still some wax residue on the sides of the jar, you can repeat the boiling water process or use a knife to scrape it off gently.
Step 6: Clean the Jar
Empty the water from the jar and wipe it down with paper towels or a cloth to remove any remaining wax or soot. If you plan to repurpose the jar, you can wash it with soap and warm water to ensure it is completely clean.
Note: The boiling water method is particularly effective for removing wax from candle jars. However, it may not completely remove the black residue that sometimes accumulates on the jar. Additionally, if your jar has decorations, such as glitter, sequins, or stickers that you cannot remove, you may need to try a different cleaning method.

Freeze the jar
The freezing method is a safe and convenient way to remove wax from a candle jar. It is best to use this method when your candle has reached the end of its life, with only about an inch of wax remaining.
Place your candle jar in the freezer and leave it overnight. The wax will shrink and loosen, separating from the edge of the jar. The colder the temperature, the better. The next day, remove the jar from the freezer and let it sit for an hour. Then, turn the jar upside down and tap the bottom gently with your hand. The wax should fall out in one large chunk. If it doesn't, you can use a spoon or a butter knife to nudge and remove it. You can also try shaking the jar or poking the middle of the wax with a spoon or knife to help dislodge it.
If there is still some wax remaining in the jar, you can place it back in the freezer for another hour or two. Once the wax has loosened enough, it should be ready to come out. Turn the jar upside down and let gravity do its work. You may need to give it a little shake or use a spoon to help dislodge the wax.
Once the wax is removed, you can clean the jar with warm water, soap, and a sponge to remove any residual wax or soot. Then, dry the jar with a dish towel or paper towel.

Heat with an oven
If you want to empty a candle jar using an oven, you should first preheat your oven to between 150 and 200 degrees Fahrenheit. While the oven is preheating, line a baking sheet with aluminium foil or parchment paper. Place the candle jar upside down on the lined baking sheet.
Once the oven is preheated, place the baking sheet inside and monitor the candle closely. Within 10 to 15 minutes, the wax should melt and pool on the foil. At this point, carefully remove the baking sheet from the oven and place it on a heat-resistant surface. Using an oven mitt, handle and remove the jar from the baking sheet.
Allow the jar to cool down to room temperature before cleaning. Once the jar is cool, wash it with soap and warm water to remove any residual wax. You can also use a spoon to remove the wick.
This method is efficient and allows you to remove wax from multiple candles simultaneously. It is also suitable for oddly shaped containers or jars with narrow necks.

Use a hairdryer
Using a hairdryer is an effective way to remove wax from a candle jar. It is particularly useful for intricate jars or grooves, and for spot-treating stubborn areas of wax.
To start, place your candle on a heat-safe surface, such as a dish towel or a potholder. This will protect your work surface from the heat. Next, put on an oven mitt to protect your hands from the heat. Turn on the hairdryer on a warm setting and direct the airflow towards the wax, heating it from the sides and the base of the candle jar. You don't need to fully melt all the wax—just heat it enough so that it becomes loose or pliable.
Once the wax is soft or liquified, carefully lift or scrape it out of the container with a utensil such as a butter knife, spoon, or fork. Be careful, as the jar may be hot. You can then wipe the inside of the jar with a paper towel and rubbing alcohol to remove any remaining wax residue.
If you are removing wax from a candle with a label, be aware that the heat from the hairdryer may cause the label to come off.

Clean with soap and water
To clean a candle jar with soap and water, you'll first need to remove the wax. One way to do this is by placing the jar in the freezer for a few hours or overnight. The wax will shrink and become brittle, making it easier to pop out in one large chunk. You can then use a butter knife to remove any remaining wax.
Once the wax is removed, you can clean the jar with soap and water. Fill the jar with hot water and a squirt of dish soap, then use a semi-abrasive sponge to scrub away any remaining wax residue or soot. You can also use an adhesive remover like Goo Gone for stubborn buildup. Wipe the jar dry with a dish towel or paper towel.
Alternatively, you can melt the wax by placing the jar in a pot of boiling water or by using a hairdryer or heat gun. Be careful not to burn the label on the jar if using this method. Once the wax is melted, use a paper towel to remove the excess wax. With the wax removed, you can then clean the jar with soap and water, using a sponge to scrub away any remaining residue.
If you're removing wax from multiple jars, you can place them upside down on a baking sheet lined with aluminum foil and put them in the oven at 150-200 degrees Fahrenheit for 15 minutes. The wax will melt and pool on the foil, which you can then throw away once it hardens. Clean the jars with soap and warm water, and be sure to let them cool before handling.
