Glass candle jars are highly versatile and can be used for storage, decoration, or even as a mould for a new candle. However, before reusing or recycling candle jars, the leftover wax must be removed. This can be done in several ways, including freezing the jar and then using a knife to remove the wax, using a hairdryer to soften the wax, or boiling water to melt it. Once the wax is removed, the jar can be cleaned with soap and warm water and reused or recycled.

What You'll Learn
Use a hairdryer or heat gun to soften the wax
Using a hairdryer or heat gun to soften candle wax is a straightforward process. Before you begin, place your candle on a protective surface, such as a dish towel or potholder. This will prevent any damage to your work surface from the hot wax. Next, put on an oven mitt to protect your hand from the heat. Turn on your hairdryer and set it to warm. If you are using a heat gun, turn it on and allow it to heat up.
Now, begin applying heat to the candle. Direct the hairdryer or heat gun at the sides and bottom of the candle. Keep the heat source moving to evenly distribute the heat and prevent overheating in one area. Continue applying heat until the wax is soft to the touch. You can test this by gently pressing the surface of the wax with your finger, protected by the oven mitt.
Once the wax is softened, it can be lifted or scraped out of the container. Use a butter knife to gently lift and remove the wax. Take care not to scratch or damage the glass with the knife. If you are reusing the wax, transfer it to a suitable container. If you are disposing of the wax, allow it to cool and harden first.
After removing the wax, inspect the candle container for any lingering wax residue or soot. If necessary, clean the container with soap and warm water to fully prepare it for its next use.

Place the jar in the freezer overnight
Freezing is a great way to remove wax from a candle jar. This method is quick, easy, and effective. It is also a good option if you have multiple candle jars to clean at once.
To start, place your candle jar in the freezer and leave it overnight. The wax will freeze and peel off the sides of the jar. If your jar has a wide mouth, this process may only take a few hours. Thick glass jars are best for this method, as thin glass may shatter due to the temperature change.
After leaving your candle jar in the freezer, take it out and turn it upside down. The wax should fall right out. If it doesn't, use a knife to gently dislodge the wax from the jar. Be careful not to use too much force, as you don't want to crack or break the glass.
Once the wax is removed, you can wash the jar with soap and warm water to remove any remaining wax residue. Now your candle jar is ready to be reused or recycled!
This freezing method is a simple and efficient way to remove wax from your candle jars. It is a convenient option if you have multiple jars to clean, as you can simply leave them in the freezer overnight and then quickly remove the wax the next day.

Boil water and pour it into the jar
Boiling water is a great way to remove wax from a candle jar. It's a straightforward process, but it requires caution to avoid burning yourself or damaging the jar. Here's how to do it:
First, boil a small amount of water in a pot. The pot should be large enough to accommodate the candle jar comfortably. Take caution not to fill the pot too high, as you want to avoid the water spilling over when you place the jar inside. Once the water has reached a rolling boil, turn off the heat.
Next, using oven gloves or heat-resistant gloves, carefully place the candle jar into the pot of boiling water. Ensure that the jar is dry before placing it in the water, as water on the outside of the jar could cause it to shatter when exposed to sudden heat. Also, be careful not to get any water inside the jar, especially on the waxy parts, as this can dilute the wax and make it more difficult to remove.
Allow the jar to sit in the hot water for a few minutes. The exact time will depend on how much wax is left in the jar. The heat from the water will melt the wax, causing it to rise to the surface. If you want to speed up the process, you can use a metal spoon or fork to help loosen the wax while the water is still hot.
After a few minutes, remove the jar from the hot water and place it on a heat-resistant surface, such as a trivet or a dry towel. Allow the jar and its contents to cool completely. As the wax cools, it will solidify, forming a disc or layer on top of the water. Depending on how much wax there was, you may need to repeat the process several times to fully remove all the wax.
Once the wax and water have cooled, you can simply pop out the wax disc with a spoon or butter knife. If there are any wicks remaining in the jar, remove them, and then wash the jar with soap and warm water to remove any residue.
And that's it! Your candle jar is now empty and ready to be reused or recycled. This method is a simple and effective way to remove wax without the need for specialized tools or equipment.

Microwave the jar
If you're looking for a quick and easy way to remove wax from a candle jar, microwaving can be an effective method. This approach is best suited for jars with a small amount of wax remaining (about 1.5 inches or less) and wide mouths, as the wax will need room to rise above the water. Here's a step-by-step guide to microwaving your candle jar:
Prepare the Candle Jar
Start by filling your candle jar with water, leaving some space at the top. The water level should be below the wax to avoid overflow when the wax melts.
Place the water-filled candle jar in the microwave and set the timer for 1 minute and 30 seconds, or a maximum of 2 minutes. Keep a close eye on the jar while it's in the microwave, as some wicks have metal wick holders that could pose a fire hazard. As the water heats up, it will melt the wax, causing it to rise above the water.
Cool and Remove Wax
Once the microwaving is complete, carefully remove the jar from the microwave using oven mitts or heat-resistant gloves. Allow the jar and its contents to cool down. As the wax cools, it will solidify, making it easier to remove. You can place the jar in the refrigerator or a cool place to speed up the cooling process.
Remove Solidified Wax
Once the wax has solidified, use a spoon or butter knife to gently pop it out of the jar. You may need to run the knife around the edges of the wax to loosen it from the jar's sides. If there is any remaining wax or residue, you can use a paper towel or a clean cloth to wipe it out.
Additional Tips
- Always exercise caution when handling hot items. Use oven mitts or heat-resistant gloves to protect your hands.
- Ensure the jar is microwave-safe before placing it in the microwave.
- If your jar has decorations or adornments, such as glitter or stickers, consider an alternative method to avoid damaging the decorations.
- For thick glass jars, microwaving is generally safe. However, if the glass is too thin, there is a risk of shattering, so it's important to proceed with caution.

Use the oven
Using the oven is an effective way to remove wax from a candle jar. It is also a good method if you have multiple candles to deal with at once. Start by preheating your oven to between 150 and 200 degrees Fahrenheit. Place your candle(s) upside down on a sheet of aluminum foil on a baking pan. It's important to stay close to the oven in case of any mishaps, but if all goes well, the wax should melt and pool on the foil within 15 minutes.
Carefully remove the pan from the oven, and take the glasses off the pan using an oven mitt. Be sure to exercise caution when handling the hot wax and glass. Once the wax has dried on the baking sheet, you can remove it from the aluminum foil. You can choose to discard the wax or reuse it for new candles or wax melt warmers.
It is important to note that this method may cause your oven to take on the scent of the candle. If you want to avoid this, consider using other methods such as the freezer method or the boiling water method.
Additionally, always exercise caution when handling hot wax and glass to prevent burns or injuries.
