What You'll Learn
Freeze the candle jar, then scrape out the wax
Freezing your candle jar is an effective way to remove wax from the jar without creating a mess. This method is best for candles at the end of their life, with only about an inch of wax left.
First, place your candle jar in the freezer for a few hours. The exact amount of time will depend on how much wax is left in the jar. If there is only a small amount of wax, you can leave it in the freezer overnight. Wax shrinks when it is frozen, allowing it to separate from the walls of its container.
Once the wax has frozen, remove the jar from the freezer. You may find that the remaining chunk of wax at the bottom pops out fairly easily and can be used in a wax warmer. If not, use a butter knife or spoon to pop out the remaining wax. Be careful not to use too much force, as the glass may be brittle and prone to breaking.
If there is still wax residue in the jar, you can fill the jar with boiling water and let it rest for a few minutes. The leftover wax should detach and rise to the top. Collect the wax and throw it in the bin, then empty the water and wash the inside of the jar with soap and water.

Use the double-boiler method
The double-boiler method is an efficient and economical way to melt wax for candle-making. It is a two-pot setup where a larger base pot contains simmering water, and a smaller pot fits inside it to melt wax gradually. This method is perfect for candle-making as it provides even heat distribution and controlled temperatures, ensuring that your wax melts with precision and care. Here is a step-by-step guide on how to use the double-boiler method:
First, gather your equipment. You will need a heat source such as a stove top or hot plate, a pot of boiling water, and a pitcher or measuring glass that will sit inside the pot. The pitcher or measuring glass should be made of glass or metal to ensure proper heat conduction.
Next, fill the larger base pot about halfway with water and place it on the heat source. The water level should be monitored carefully, as it plays a crucial role in achieving precise wax melting. The optimal level is usually about half an inch below the top of the smaller container to ensure consistent and even heating.
Once the water is simmering, place the smaller container, such as a pouring pitcher or measuring glass, inside the larger pot. The container should be heat-resistant and able to withstand the temperature of boiling water (185°F - 212°F). Place your wax in this smaller container.
Heat the setup over medium-low heat until the wax is completely melted. Use a thermometer to monitor the temperature, which should reach around 185°F for adding fragrance. Remember to stir the blend briefly before taking any temperature readings to ensure an even distribution of heat.
Once the desired temperature is reached, remove the smaller container from the heat and gently stir in your desired amount of fragrance oil. Add colour if desired, stirring thoroughly to ensure an even blend. Remember, more dye typically darkens the colour, and different waxes take on colour in different ways. Soy wax, for example, will appear more muted or pastel-like compared to paraffin, which closely matches the colour.
Finally, carefully pour your wax blend into your candle container at a steady rate. Avoid introducing too much air into the blend, and if making multiple candles, pour about 75% of the wax into each container and then top them off in the same order.

Melt wax with a heat gun or hairdryer
If you want to clear wax out of a candle jar, you can use a heat gun or a hairdryer. This method is more direct than boiling water in a separate container and then pouring it into the jar. With a heat gun or hairdryer, you can directly apply heat to the wax, melting it and allowing you to pour it out.
First, grab some paper towels and have them at hand. Then, turn on your heat gun or hairdryer and set it to high heat. Direct the hot air at the wax, and you'll soon see it start to melt. Switch to low heat once the wax begins to melt. You can then use the paper towels to mop up the melted wax.
Be careful not to overheat the glass container. Although glass can withstand high levels of heat, it is still fragile and can explode if it gets too hot. This is true of the freezing method too. Always use your best judgment depending on the jar.
Once you've mopped up as much wax as possible, you can then use soap and warm water to wash the jar. You could also use rubbing alcohol for this step.

Melt wax in the oven
Melting wax in the oven is a great way to clear a candle without creating any mess. It is a simple process that allows you to reuse the wax and the jar. Here is a step-by-step guide:
First, preheat your oven to 200 degrees Fahrenheit. While the oven is heating up, prepare your candle by removing any labels or stickers from the jar. It is important to ensure that the jar is made of oven-proof glass to avoid any accidents. Place the jar on a cookie sheet to make it easier to handle and to catch any potential drips.
Next, put the candle jar in the oven. The amount of time it takes for the wax to melt will vary depending on the amount of wax and the temperature of your oven. It can take anywhere from 30 minutes to an hour for the wax to completely melt. Keep an eye on the candle and check on it periodically to avoid over-heating.
Once the wax has melted, carefully remove the jar from the oven using oven mitts to protect your hands. Set the jar on a heat-resistant surface and allow the wax to cool. As the wax cools, it will harden and you will be left with a fresh, clear candle.
If you want to reuse the wax, you can scoop it out of the jar once it has cooled and hardened. You can then use the wax for various projects, such as making new candles, wax melts, or scented sachets. Just ensure that you never pour molten wax down the drain as it can cause blockages.
It is important to note that you should not use a microwave to melt wax as the metal wick holders can ruin your microwave and even start a fire. Always be cautious when handling hot wax and glass to avoid any accidents or injuries.

Clean the jar with soap and hot water
When it comes to cleaning out candle jars, there are several methods you can use to remove old wax. Here is a detailed, step-by-step guide focused on cleaning your jar with soap and hot water:
Firstly, it is important to remove any large pieces of wax from your jar. One way to do this is by placing your jar in the freezer for a few hours. Wax will become brittle once frozen, so after removing the jar from the freezer, you can use a butter knife to scrape away the wax.
Now that the large chunks of wax have been removed, it is time to melt the remaining wax. Fill a bowl or pot with boiling water and gently place the candle container in it for a few minutes. Ensure that you do not overfill the container with water, leaving at least an inch of space at the top. The heat from the water will melt the wax, allowing it to detach from the sides of the jar and rise to the top.
At this point, you can discard the wax that has risen to the surface. Carefully pour out the water, being mindful not to pour wax down the drain as it can solidify and cause clogs. You may need to use a spoon or butter knife to gently loosen any remaining wax. Once the majority of the wax has been removed, you can wash the jar with soap and hot water. Use a semi-abrasive sponge and some dish soap, scrubbing thoroughly to remove any remaining wax residue. You may need to repeat this process a few times to ensure that all the wax is removed.
Finally, dry your jar with a cloth towel, and it will be ready for reuse! Remember to always exercise caution when handling hot water and glass containers. While glass can withstand high levels of heat, it is still fragile and can shatter if overheated. Always use oven mitts or tongs to handle hot jars, and never leave a heating element unattended to prevent accidents.

Frequently asked questions
There are several ways to do this, but one of the most popular methods is to boil water in a pot, place the jar in the pot for a few minutes, and then gently jab the wax with a spoon or butter knife to loosen it.
No, you should never use the microwave to melt wax. The wick holders are made of metal, which could not only ruin your microwave but also start a fire.
The double boiler method is when you pour hot water into a large pot or container, place your candle in a smaller bowl, and set that bowl on top of the container with hot water inside. This method is better if you want to maintain the integrity of the label.
You can place the candle in the freezer for a few hours, then pop the wax out with a knife.
You can save the old wax to use in wax melt burners, or throw it away. Just be sure to never pour molten wax down the drain as it will re-solidify and cause clogs.
