Candle wax discoloration is when the color of the candle wax changes after it has been burned. This can occur for a variety of reasons, such as the fragrance used, exposure to UV rays, or overheating during the candle-making process. It is important to fix discolored candle wax because it can affect the appearance of the candle, which can be unappealing to consumers.
Additionally, discolored candle wax can sometimes indicate that the candle was not made properly, which can affect the candle’s burn time and fragrance throw. Fixing discolored candle wax can help to ensure that the candle performs well and looks attractive.
Common causes of candle wax discoloration after burning
Vanillin or citrus in fragrance
Some fragrances, particularly those that contain vanillin or citrus, can cause candle wax to discolor after burning. Vanillin is a compound found in vanilla, and it can cause candle wax to yellow or brown over time. Citrus fragrances can also cause candle wax to discolor, as they can break down the wax and cause it to become cloudy or yellow.
UV ray exposure
Exposure to UV rays can cause candle wax to discolor over time. UV rays can cause the wax to fade or yellow, particularly if the candles are stored in a sunny location or are left in direct sunlight for extended periods of time.
Overheating during candle making process
Overheating the wax during the candle-making process can also cause discoloration. If the wax is heated too quickly or too high of a temperature, it can cause the wax to yellow or brown, as well as create other issues such as cracking, poor fragrance throw, and rough tops.
Common candle discoloration issues
Yellowing or browning of wax
One common candle discoloration issue is the yellowing or browning of the wax. This can occur over time due to a variety of factors, such as the fragrance used, exposure to UV rays, or overheating during the candle-making process. The yellow or brown color may appear on the entire candle or just on certain areas, such as the bottom or top.
Oily or yellow spots on the surface
Another common issue is the appearance of oily or yellow spots on the surface of the candle. These spots can be caused by a variety of factors, such as the fragrance used or the way in which the candle was made.
Fading of color over time
Candle wax can also fade in color over time, which can affect the overall appearance of the candle. This can be caused by a variety of factors, such as exposure to UV rays or the quality of the dye used in the candle.
Cloudy wax
Cloudy wax is another common discoloration issue that can affect the appearance of a candle. This can be caused by using low-quality wax or by overheating the wax during the candle-making process.
Frosting
The frosting is a type of discoloration that appears as a white coating on the surface of the candle. This can be caused by using low-quality wax or by overheating the wax during the candle-making process. Frosting can also be caused by using certain fragrances, such as those that contain vanillin.
How to fix candle wax discoloration after burning
If your candle has become tunneled, meaning that the wax has burned down the center and left a hole around the wick, you can use the aluminum foil trick to fix it.
To do this, wrap a piece of aluminum foil around the edges of the candle, making sure to leave an opening in the center for the wick to burn. The foil should hang over the built-up wax areas. Let the candle burn for a few hours, and the wax should melt and even out the surface. Melting and reusing leftover wax
If you have leftover wax from nearly depleted candles, you can melt it and reuse it to make new candles. To do this, you can melt the wax in a double boiler or use a slow cooker. Once the wax has melted, you can pour it into a new candle mold or container and add a new wick. Just be sure to let the wax cool to the correct temperature before adding the wick to prevent it from collapsing.
How to prevent candle wax discoloration in the first place
To prevent candle wax discoloration in the first place, there are a few steps you can take.
Choosing fragrances that are less likely to discolor
Some fragrances, such as those that contain vanillin or citrus, are more likely to cause candle wax to discolor. To prevent this, consider using fragrances made with essential oils, which are less likely to cause discoloration.
Avoiding overheating the wax during the candle-making process
Overheating the wax during the candle-making process can cause a variety of issues, including discoloration. To prevent this, make sure to follow the recommended temperature guidelines for melting and pouring the wax.
Storing candles in a cool, dry place
Exposure to UV rays and heat can cause candle wax to discolor over time. To prevent this, store your candles in a cool, dry place away from direct sunlight and heat sources.
Using high-quality dyes for colored candles

FAQs
Can you fix discolored candle wax after it has already been burned?
Yes, you can fix discolored candle wax after it has been burned, although the methods you can use will depend on the specific cause of the discoloration. For example, if the candle has become a tunnel, you can use the aluminum foil trick to even out the surface. If the discoloration is due to UV ray exposure or the fragrance used, there may not be a way to fix it after the candle has been burned.
Can you add color to discolored candle wax?
It is possible to add color to discolored candle wax, although the results may vary depending on the specific cause of the discoloration. To add color to discolored candle wax, you can melt the wax and add a candle dye specifically formulated for candle making. Mix the dye thoroughly into the wax and pour it into a new mold or container to create a new candle.
Can you use any type of wax to make candles?
Not all types of wax are suitable for candle making. Some types of wax, such as beeswax and soy wax, are commonly used for candle making because they are easy to work with and have a good fragrance throw. Other types of wax, such as paraffin wax, can be used for candle making but may not perform as well as beeswax or soy wax. It is important to choose a wax that is specifically formulated for candle-making to ensure the best results.
Can you fix a candle that has a wick that won’t stay lit?
If a candle’s wick won’t stay lit, there are a few steps you can try to fix it. First, make sure the wick is trimmed to the correct length, which is typically about 1/4 inch for most candles.
If the wick is too long, it may not stay lit because it is not getting enough oxygen. You can also try replacing the wick with a new one if the original wick is damaged or too short. Finally, make sure the candle is stored in a cool, dry place and avoid drafts that can cause the wick to go out.
