Removing wax with hot water
Firstly, remove as much wax as possible from the jar using a butter knife or a spoon. Be careful when handling the jar, especially if the wax is still warm, and consider using an oven mitt or pot holder to protect your hands. Next, place the jar in a pot or large metal bowl on a heat-safe surface. You can put a folded dish towel under the jar to prevent it from moving.
Now, carefully pour boiling water into the pot around the jar, ensuring that the water does not get into the candle jar itself. Allow the jar to sit in the hot water until the remaining wax has softened and melted. The hot water will melt the wax, causing it to float to the top of the water.
Once the wax has softened, carefully remove the jar from the hot water. You can then pop out the softened wax using a spoon or butter knife. Finally, wash the jar with soap and warm water to remove any remaining wax residue or soot. You may need to repeat this step a few times to ensure that all the wax is removed.
Alternatively, you can fill the candle jar itself with boiling water. Pour boiling water directly into the jar, filling it about halfway as the wax will rise to the surface. Allow the jar to sit until the water has cooled, then remove the wax from the surface. You can then wash the jar with soap and water to remove any remaining residue.
Using hot water is a quick and easy way to remove wax from candle jars, giving them a new lease of life for storage or decoration.

Using the freezer to pop out wax
The easiest and cleanest method to remove wax from a candle jar involves freezing the wax, which shrinks it and makes it separate from the edges of the jar. This method is best for candles at the end of their life, with only about an inch of wax left. Place your candle jar in the freezer for a few hours or overnight.
To check if the wax is frozen, push down on it. If it moves, it's frozen. Take the candle jar out of the freezer and turn it upside down to remove the wax. You can also use a butter knife to pop the wax out. If the wax is not coming out, put it back in the freezer for a little longer and try again.
Once the wax is removed, you can use soap and water or baby oil to wash the candle jar and remove any remaining residue. This process can be messy, so spread out newspapers or old rags to protect your work surface.
After cleaning, you can repurpose the candle jar as a storage container for small items such as paper clips, rubber bands, coins, or cotton balls.

Cleaning with soap and water
Cleaning candle jars with soap and water is an effective way to remove wax residue and soot. This method is suitable for glass candle jars without decorations such as glitter, sequins, or stickers.
First, let the candle jar cool to room temperature. If there is leftover wax in the jar, you can place it in the freezer overnight. The wax will freeze and peel off the sides, making it easier to remove with a knife or spoon. You can also use a hairdryer on a warm setting to soften the wax and then lift or scrape it out with a butter knife.
Once most of the wax has been removed, fill your sink with warm water and let the jar soak for about 30 minutes. This will help loosen any remaining wax. Keep in mind that soaking the jar may cause the label to come off. After soaking, use an abrasive sponge or scrubber and some dish soap or washing-up liquid to scrub the jar thoroughly. Repeat this step once or twice if necessary.
Finally, rinse the jar with warm water and dry it thoroughly. Your candle jar is now clean and ready to be reused or repurposed as a storage container or decorative item.

Scraping wax with a knife
Scraping wax out of a candle jar with a knife is a straightforward process, but it may require a few steps beforehand to ensure the wax is soft enough to scrape. Here is a detailed, step-by-step guide:
First, you must ensure that the wax is soft enough to be scraped out with a knife. One way to do this is to place the candle jar in the freezer overnight. Wax shrinks when frozen, making it easier to separate from the jar. The next day, take the jar out of the freezer and turn it upside down. The wax should pop right out. If it doesn't, you can use a butter knife to help loosen and lift the wax out of the jar.
Alternatively, you can use a hairdryer or heat gun to melt the wax. Hold the candle jar with an oven mitt and use the hairdryer to heat the wax from the sides and bottom. Once the wax is soft to the touch, you can use a butter knife to lift and scrape it out of the container.
If you are dealing with softer wax, such as soy or coconut wax, you can use hot water to melt the wax without applying direct heat. Pour hot water into a large pot or container, then place the candle jar into a smaller bowl and set that bowl on top of the container with hot water. As the candle wax softens, it will be easy to pop out with a knife.
Once you have removed the wax, you may need to clean out any lingering wax residue or soot from the jar. To do this, use warm water, soap, and a sponge to clean the container before wiping it dry with a dish towel or paper towel. For stubborn wax residue, you can use an adhesive remover, such as Goo Gone.

Soaking in the sink
So, you've burned your candle down to the bottom and are now left with a waxy, sooty jar. Not to worry—with a little elbow grease, you can have it clean and ready for its next use in no time. Here's a step-by-step guide to cleaning your candle jar through the "soaking in the sink" method:
First, ensure your jar is cool to the touch. If you've just blown out your candle and there's still some liquid wax in the jar, give it some time to cool and harden.
Next, fill your sink with warm water. Remove the lid from your candle jar, if it has one, and place the jar in the sink, making sure the opening is submerged below the water level. Let the jar soak for around 30 minutes. The warm water will help to melt and loosen the wax, making it easier to remove. Keep in mind that soaking your jar in warm water may cause any labels on the exterior to come off.
After your jar has soaked, use a butter knife or spoon to gently lift and remove the wax from the bottom and sides of the jar. If there's still some wax residue or soot left inside, you can use an abrasive sponge or bottle brush, along with some dish soap, to scrub it away. If you're having trouble getting rid of stubborn residue, you can try using an adhesive remover like Goo Gone, or a paste made from baking soda and water.
Finally, rinse your jar with warm water and dry it with a dish towel or paper towel. Your candle jar is now clean and ready for its next use!
This method is simple and effective for removing wax from candle jars. However, if your jar has decorations or embellishments like glitter, sequins, or stickers that you can't remove, you may need to try a different cleaning technique, such as using a hairdryer to melt and lift the wax, or freezing the jar to shrink the wax for easier removal.
