Make new candles
Making new candles from leftover wax is a great way to reuse old candles. It's a simple process, but it requires some care and attention to safety.
Firstly, you'll need to gather your materials. Leftover wax, of course, is essential. You'll also need a heat-safe container, such as a glass jar, mug, or old candle holder. You can also use a stainless steel melting pot with a hook to prevent it from sliding. If you don't have one of these, a bain-marie or a small pot that fits inside a medium pot will work. You'll also need a fresh wick, which can be purchased from a craft store or online. Other useful items include gloves or tongs for handling hot items, tweezers for removing old wicks, and a pencil to secure the new wick in place.
Now, you're ready to melt the wax. Fill a pot with about 2 inches of water and bring it to a boil. Place your old candles into the pot to melt. You can also use the oven, preheated to its lowest setting, placing the jar inside with any labels or stickers removed. If you're melting the wax in a pot, turn off the hob before placing the candles inside. Using tweezers, remove any metal wick holders, leftover wicks, and matchsticks. Then, pour the leftover melted wax into a smaller pot or a jug for easier pouring. Repeat this process for each old candle, combining the wax in one container.
Once the wax has fully melted, you can add colour and scent. It's best to start with small amounts and build up, as too much dye or essential oil can affect how well the candle burns. Get creative and put your own mark on your candles!
Now, it's time to pour the wax into your chosen container. Make sure your wick is centred and secured, then carefully pour the wax in. Set your candle on a flat surface out of the way and allow it to cool for 24 hours before lighting.
And that's it! You've created a recycled DIY candle that's kind to the environment and your wallet.

Make wax melts
Wax melts are a great way to reuse leftover candle wax. They are decorative, fragrant, and easy to make. Here is a step-by-step guide to making your own wax melts:
Preparing the Wax
First, ensure you have a mostly burnt-out candle with about an inch or less of wax remaining at the bottom. If your candle is not already completely melted, you can light it until the wax melts or use an alternative method to melt the wax.
Do not use a microwave to melt the wax, as many candles have metal at the base of the wick, which could damage your microwave or cause a fire. Instead, place the candle in a heatproof container, such as a glass jar or metal mug, and fill a deep pan or pot with enough water to cover the sides. Slowly heat the water and place the container in the water to melt the wax gently. Alternatively, you can use a double boiler method to melt the wax.
Preparing the Moulds
While the wax is melting, prepare your moulds. You can use a silicone mould or any kind of dish, jar, or container. Avoid using plastic as it may melt. Place your moulds on a paper towel or cardboard box to catch any spills.
Pouring the Wax
Once the wax is completely melted, carefully pour it into your prepared moulds. Fill the moulds almost to the top and allow the wax to cool.
Removing the Wax Melts
After the wax has cooled and hardened, pop the wax melts out of the moulds. If the wax is not fully hardened, you can place the moulds in the refrigerator to speed up the process.
Storing the Wax Melts
Once your wax melts are completely cool, you can store them. You can keep them in a sealed bag or container or even reuse one of your empty candle jars.
Using Your Wax Melts
Finally, enjoy your wax melts! Place them in a wax warmer to release the fragrance and fill your space with your favourite scent. You can also give them as gifts or use them for decorative purposes.
Making wax melts is a fun and easy way to upcycle your leftover candle wax and enjoy your favourite fragrances for longer.

Make scented potpourri
There are many ways to reuse leftover candle wax, such as making new candles, wax melts, or scented sachets. One great option is to make scented potpourri, which can be used to fill decorative bowls or jars and add a pleasant aroma to your home. Here's how to do it:
First, you'll need to melt down your leftover candle wax. To do this, place your candle in a small pot and then place that pot inside a larger pot filled with water. Bring the water to a simmer, and the wax will gradually melt. Different types of wax have different melting points, so some may take longer to melt. Once the wax is melted, remove any old wicks with tongs and discard them.
Next, it's time to add your scent. You can use essential oils, dried herbs, or even dried flowers for a pleasant fragrance. If you're using essential oils, just add a few drops to the melted wax and stir gently. If you're using dried herbs or flowers, simply mix them into the wax until well combined. You can also add decorative items like dried orange slices or cinnamon sticks for a more visually appealing potpourri.
If you want to get creative, you can even add colour to your potpourri. Use wax dyes or crayons to achieve your desired colour. Just be sure to use a heat-resistant surface when working with melted wax.
Once you've added your scent and any desired colours or decorative items, it's time to let your potpourri harden. You can pour the mixture into a mold and let it cool, or simply pour it into a bowl or jar and let it harden directly in the container.
Once your potpourri is hardened, it's ready to use! Place it in any room of your home to add a pleasant scent and a decorative touch. You can even use it in your drawers or closets to keep your clothes smelling fresh.
Making scented potpourri is a great way to recycle and repurpose your leftover candle wax. It's easy to do, and you can get creative by mixing and matching different scents and colours to create a unique aroma in your home.

Leftover candle wax can be used to create decorative objects for your home. Here are some ideas to get you started:
Wax Melts
Leftover wax can be melted down and poured into small moulds, such as an ice cube tray, to create decorative wax melts. You can add your own colouring, essential oils, or decorations to personalise your creations. These wax melts can be used in a candle warmer to release a delicate fragrance into your home.
Fragrance Pouches
Another way to enjoy your favourite candle fragrance is to create scented pouches. Melt the leftover wax and pour it into textile pouches. You can use pre-made bags or get creative with off-cuts of your favourite fabrics to suit your style. Linen is a great option for a contemporary space, while burlap is perfect for a rustic look.
DIY Tealights
If you have enough leftover wax, you can create your own miniature candles. All you need is a small tealight cup, a wick, and your melted wax. You can use a heat-safe container, such as a glass jar or mug, to melt the wax slowly over hot water. Centre the wick using a pencil, and then pour in the melted wax.
New Candles
With enough leftover wax, you can create a brand new candle. Melt the wax slowly over hot water and pour it into a heat-safe container, such as a jar or mug. Remove any old wicks and metal wick holders, and secure a new wick in the centre with a pencil. Cover the wick with a thin layer of wax to hold it in place.
By following these simple steps, you can create beautiful and functional decorative objects from your leftover candle wax, giving new life to your favourite fragrances and reducing waste.

Make natural insect repellent
Leftover candle wax can be reused in many creative ways, including making natural insect repellents. Here are some ways to do this:
Melt and Mould
One way to reuse leftover candle wax is by melting it down and pouring the liquid wax into moulds. You can use tea light moulds or other creative shapes. Once the wax has hardened, you can place these candles around your outdoor spaces. To make them insect-repelling, add essential oils like citronella, eucalyptus, rosemary, geranium, or lavender to the melted wax before pouring it into the moulds. These essential oils are known to repel insects, and you can adjust the amounts and combinations to suit your preference.
Insect-Repellent Sticks
Another method is to create insect-repellent sticks. After melting the leftover candle wax, pour the mixture into a mould and let it cool and harden. Once solid, insert sticks into the ground around your outdoor areas. The sticks will keep bugs at bay without the worry of the wax melting in the sun.
Floating Candles
For a creative and decorative option, you can make floating candles that repel insects. Slice up grapefruits and lemons, and layer them with sprigs of rosemary in a jar. Fill the jar with water and add 8-10 drops of citronella essential oil. Finally, top it off with a floating candle. This natural insect repellent candle is not only effective but also adds a pleasant aroma and a decorative touch to your outdoor spaces.
Scented Tea Lights
If you prefer more subtle and discreet insect repellent options, you can create your own scented tea lights using leftover candle wax. Melt the wax and add your chosen essential oils known for their insect-repelling properties, such as citronella or eucalyptus. Pour the scented wax into tea light moulds and let them harden. These tea lights can be placed in various areas of your home or outdoor spaces, providing both illumination and a natural defence against insects.
By reusing leftover candle wax, you not only reduce waste but also create customised, natural insect repellents that are safe and effective alternatives to store-bought options.
