Candle jars can be reused or recycled, but throwing them away in the trash is not a good idea. Glass can take thousands of years to break down in a landfill, so it is important to dispose of candle jars properly. Candle wax can be removed by freezing the jar and popping out the wax with a knife, or by pouring boiling water into the jar and letting the wax float to the top and harden. The jar can then be recycled or reused for storing bulk food items, as a to-go mug, or for homemade beauty products.

What You'll Learn
Removing wax with boiling water
If you're looking to recycle candle jars, you'll first need to remove the wax. One way to do this is by using boiling water. Here's a step-by-step guide:
Firstly, place your spent candle on a protective surface, such as a dish towel or a potholder. This will help catch any spills and protect your work surface from the hot water. Next, boil some water. You'll need enough to fill the candle jar, so boil a little extra to account for any evaporation. Once you have boiled your water, carefully pour it into the candle jar, leaving an inch or so of space at the top. The amount of wax in the jar will determine how much water you need to add. The wax will rise to the top as it melts, so ensure you don't overfill the jar.
Now, let the jar sit until the water has cooled. The wax will float to the surface and harden into a solid cake. This may take a few hours or even overnight. Once the water has cooled, carefully remove the hardened wax from the top of the jar. If there is any remaining wax stuck to the bottom or sides of the jar, simply repeat the process with more boiling water.
Finally, give the jar a good wash with soap and warm water to remove any remaining wax residue. You can also use a sponge or dish brush to scrub away any stubborn bits. And that's it! Your candle jar is now ready for recycling or repurposing.
This method is an effective way to remove candle wax without resorting to intense methods like the microwave, which may be too harsh for softer waxes. It's also a good option if you have multiple jars to clean at once, as it doesn't require constant supervision.

Removing wax by freezing
Removing wax from candle jars can be a tedious task, but freezing is an effective method to make the process easier. Here is a step-by-step guide on how to remove candle wax from jars by freezing:
Step 1: Prepare the Jars
Start by ensuring the jars are ready for the freezing process. Remove any remaining wick from the jars and scrape out as much wax as possible with a spoon or knife. This initial step will make the subsequent freezing process more effective.
Step 2: Freeze the Jars
Place the candle jars in your freezer, ensuring they are on a level surface and won't be disturbed. Leave the jars in the freezer for several hours or overnight. Wax hardens and shrinks when frozen, so this step will help it separate from the walls of the jar.
Step 3: Remove the Frozen Wax
After the wax has frozen, it's time to remove it. Take the jars out of the freezer and use a butter knife or spoon to gently loosen the edges of the wax from the container. Thick chunks of wax should pop out easily, but thinner layers might require more effort. If the wax is stubborn, put the jar back in the freezer for another hour or two.
Step 4: Use Gravity
For sizable chunks of wax that remain, turn the jar upside down and let gravity do its work. You may need to give the jar a gentle shake to help dislodge the wax. If it still doesn't come out, use your spoon or knife to poke at the middle of the wax and try to pull or dig it out.
Step 5: Scrape Remaining Wax
Even after the previous steps, there may still be small pieces of wax stuck to the jar. Use a spoon to gently scrape off as much of the remaining wax as possible. If there is only a thin residue left, you can proceed to the next step.
Step 6: Remove Wax Residue
To eliminate the final traces of wax, dip a paper towel into some household cooking oil and wipe the inside of the jar. The oil will help dissolve the wax, which can then be wiped up with the paper towel. You can use any type of oil, such as canola oil, olive oil, or even baby oil.
Step 7: Wash the Jar
Finally, wash the jar with warm water and dish soap to remove any remaining wax flakes or oily residue. You can use a sponge or dishcloth to gently scrub the jar until it is clean.
By following these steps, you can effectively remove candle wax from jars by freezing, leaving you with clean jars ready for recycling, repurposing, or upcycling.

Removing labels
Soaking in Hot Water
One popular method is to soak the candle jar in hot water. Fill a sink or a large container with hot water and fully submerge the jar, making sure the water covers the entire label. Let the jar soak for several minutes, or even up to an hour for stubborn labels. The hot water will help soften the adhesive, making it easier to remove the label. After soaking, carefully remove the jar from the hot water and start peeling off the label gently. If needed, use a butter knife or a similar tool to gently scrape off any remaining adhesive.
Using Natural Oils
Natural oils, such as coconut oil, olive oil, or baby oil, can be very effective in removing labels and their sticky residue. For this method, prepare a mixture of equal parts coconut oil and baking soda, creating a paste-like consistency. Apply this paste generously over the label and let it sit for about 30 to 45 minutes. The paste will work its way into the adhesive, making it easier to remove. After the waiting period, use a cloth or paper towel to gently rub and wipe away the label and any remaining residue. Finally, wash the jar with warm soapy water to remove any oily residue.
Commercial Adhesive Removers
If natural methods are not effective for particularly stubborn labels, you can try using commercial adhesive removers. Products like Goo Gone or nail polish remover (with acetone) can be effective in breaking down the adhesive. Apply the product to a paper towel or cloth and gently rub it over the label and adhesive residue. Be cautious when using these products, as they may have strong fumes. Always work in a well-ventilated area and follow the manufacturer's instructions for safe use.
Alternative Methods
There are a few other methods that have been suggested by creative individuals. One is to use a special pen-like product, such as the Loctite Glue Remover Gel, which can be applied directly to the adhesive to help remove it. Another suggestion is to use a razor blade, carefully sliding it under the label to lift and remove it, but this method should be approached with caution to avoid damaging the jar.
Remember, when removing labels from candle jars, it's important to be patient and gentle to avoid damaging the jar or injuring yourself. Always handle hot water with care and test any products or methods on a small area first to ensure they won't damage the surface of the jar.
