If you have leftover candle wax sitting around, don’t throw it away. Turning old candles into wax melts is an easy way to reuse leftover wax and enjoy your favorite fragrances in a new form.
With a few basic supplies and some simple steps, you can transform unused candle wax into homemade wax melts for your wax warmer. This DIY project is a practical way to reduce waste while making use of candles that are no longer easy to burn.
What You’ll Need
Before starting, gather your materials:
- Old candles: Use leftover candle wax from candles you no longer need. Make sure the wax is completely cool before handling.
- Double boiler or heat-safe bowl and pot: A double boiler setup helps melt wax gently and evenly.
- Silicone molds: Heat-resistant silicone molds are ideal for creating wax melts in different shapes.
- Oven mitts: Use them when handling hot candle jars or melted wax.
- Paper towels or cardboard: Place them under your workspace to protect surfaces from spills.
- Storage container: Keep your finished wax melts in a clean, dry container.
A plastic knife can also be useful if you plan to pour the wax onto a flat surface and break it into smaller pieces after it hardens.
Step 1: Melt the Candle Wax
If there is still wax inside the candle jar, you can melt it using a double boiler method.
Place a washcloth at the bottom of a pot to prevent the candle jar from sitting directly on the hot surface. Put the candle jar on top of the cloth, add water to the pot, and heat it over low to medium heat until the wax melts completely.
Be careful when handling the jar because it can become very hot. Avoid placing candle jars directly on a stovetop burner, and do not microwave candle containers unless you are certain they are microwave-safe.
Step 2: Prepare Your Wax Melt Mold
While the wax is melting, prepare your mold.
Silicone molds work best because the hardened wax can be removed easily. Make sure the mold is heat-resistant and placed on a protected surface in case of spills.
Avoid using regular plastic molds, as they may soften or melt when exposed to hot wax.
Step 3: Pour the Melted Wax
Once the candle wax has fully melted, carefully pour it into the mold.
Fill each section almost to the top, but leave a little space to prevent overflow. If you don’t have a mold, you can pour the wax onto a shallow heat-resistant dish or pan. After the wax hardens, break it into smaller pieces and use them as wax melts.
If you want to combine wax from multiple candles, make sure the scents work well together before mixing them.
Step 4: Let the Wax Cool and Harden
Allow the wax melts to cool completely at room temperature before removing them from the mold.
Cooling naturally helps the wax maintain its shape. If you need to speed up the process, you can place the mold in the refrigerator for a short time, but avoid cooling the wax too quickly as this may affect the final texture.
Step 5: Remove and Store Your Wax Melts
Once the wax is firm, gently remove the melts from the mold and place them in a clean, dry container.
You can reuse candle jars or other airtight containers for storage. Keeping wax melts away from heat and direct sunlight helps preserve their scent and texture.
How Do You Make Wax Melts from Glass Candles?
To make wax melts from candles in glass jars, use the double boiler method. Place the jar in a pot of simmering water until the wax becomes liquid, then carefully pour the melted wax into silicone molds.
Avoid microwaving glass candle jars because many candle containers are not designed for microwave use and may crack or break.
How Do You Melt Wax Out of a Candle Jar?
One common method is to fill the candle jar with hot water. The heat softens the remaining wax, causing it to loosen from the sides of the container. Once the wax cools and solidifies, it can usually be removed more easily.
For softer waxes, such as soy wax, warm water may be enough to soften the wax without using boiling water.
Can You Turn Old Candles into Wax Melts?
Yes. Leftover candles can be reused to make wax melts by melting the remaining wax and pouring it into molds.
Keep in mind that the final scent strength may vary depending on the original candle’s fragrance concentration and how much wax remains.
Can You Cut Up a Candle to Make Wax Melts?
Yes, leftover candle wax can be cut into smaller pieces and used in a wax warmer.
However, make sure the wax is suitable for your wax warmer. Some candles contain additives, decorations, or materials that may not be ideal for melting again.
Can You Melt Candle Wax in the Microwave?
Although candle wax can technically be melted in a microwave using a microwave-safe container, it is generally not the preferred method.
Wax can heat unevenly, and overheating may create safety risks. A double boiler provides better temperature control and is usually the safer option for melting candle wax.
Final Thoughts
Making wax melts from old candles is a simple DIY project that helps you reuse leftover wax instead of throwing it away. With proper heating, safe handling, and suitable molds, you can turn unused candle wax into new wax melts and continue enjoying your favorite scents.
