Candles do not typically have an expiration date, but their quality can degrade over time. While some sources suggest that candles are best used within a year of purchase, others claim that they can last for several years, especially if stored correctly. Storing candles in a refrigerator is not recommended as it can introduce unwanted moisture, and cause the wax to cool too quickly, leading to cracking or separation from the glass. Instead, it is best to keep candles at room temperature, away from direct sunlight and other harsh lights, to preserve their colour and scent.

What You'll Learn
Candles shouldn't be stored in fridges or freezers
While storing candles in the fridge may seem like a good idea to keep them cool and preserved, it is not recommended. The introduction of moisture from the refrigerator can negatively impact the candle. Fragrance oils and waxes are sensitive to heat, but they are also sensitive to moisture. The moisture from the fridge can cause the wax to crack or separate from the glass, especially if the candle is subjected to rapid temperature changes.
Additionally, the cold temperature of the fridge can cause the wax to cool too quickly, which can lead to issues such as sweating. Sweating occurs when there are small oily droplets on the surface of the candle, which can leave marks. While this is not necessarily a problem, it can be unsightly and may be undesirable for those seeking a premium experience from their candles.
Storing candles at room temperature is generally considered the best option. Keeping them away from direct sources of heat, such as radiators, space heaters, or kitchen appliances, is recommended. A cool, even temperature below 80 °F is ideal. This will help prevent the wax from softening and preserve the fragrance for a longer period.
To further prolong the lifespan of scented candles, it is recommended to keep them covered when not in use. This helps to preserve the scent and keeps dust and other particles from accumulating on the candle, which can affect the burn. Storing candles in their original packaging or under a bell cloche are effective ways to achieve this.

Room temperature is best for candle storage
Storing candles in a fridge is not recommended. Extreme cold can be just as detrimental to candles as extreme heat. The wicks of candles stored in a fridge or freezer may absorb too much moisture, making them difficult to light and damaging their ability to burn evenly and cleanly. Refrigeration can also introduce unwanted moisture to the wax itself, causing it to crack or separate from glass containers.
Candles should be stored in a cool, dry place, away from direct sunlight, harsh indoor lighting, and sources of heat such as radiators, heaters, and other candles. Basements are a good option, as long as they do not flood. Dark cabinets, closets, and drawers are also suitable, as they protect candles from light exposure while maintaining a consistent temperature.
Other factors to consider when storing candles include fire safety and accidental damage. Candles should be kept out of the reach of children and pets, and away from flammable materials. High-traffic areas may not be ideal for candle storage, as there is a greater risk of candles being knocked over or damaged.
To maintain a candle's scent and colour, it should be stored in its original box or an airtight container, away from sunlight. Tissue paper can also be used to wrap individual candles and protect them from scratches and dents.

Candles don't have an expiration date
Candles do not have a hard expiration date, but they do degrade over time. The rate of degradation depends on the type of wax used and how the candle is stored. While the wax itself does not expire, scented candles can lose their fragrance over time, even when unlit. This is due to the constant evaporation of fragrance oil molecules from the wax into the air. However, this process is gradual and may not be noticeable for the first six months to a year.
Beeswax candles are known to have an exceptionally long shelf life and are favoured in emergency kits for this reason. They have been found in sunken ships several hundred years old and were still capable of burning beautifully once the wick was dried out. Paraffin candles are also long-lasting and can last almost indefinitely when stored properly.
On the other hand, organic, vegetable-based waxes like soy and coconut are more prone to breaking down over time. These types of candles are best used within a year or two. To prolong the life of your candle, it is recommended to store it in a cool, dry place, away from direct sunlight and harsh lights. Avoid areas with high humidity or moisture, such as bathrooms, and sudden temperature changes.
While it may be tempting to store candles in the refrigerator to keep them cool, this is not recommended as it can introduce unwanted moisture. Room temperature is best for candle storage. Additionally, keeping candles in their original packaging can help preserve their scent and prevent the accumulation of dust particles, which can affect the burn.

Candles may crack if frozen
Candles are best stored at room temperature. While it may be tempting to store candles in the refrigerator to keep them cool, this can introduce unwanted moisture. It can also cause the wax to cool too quickly, leading to cracks on the surface.
In extremely cold climates, candles may become brittle and harder, but they do not freeze in the same way that water does. However, if the temperature drops low enough, candles may crack or become brittle, which will affect how evenly the candle burns.
The cooling process is the primary cause of candle cracking. When candles cool too quickly, the wax undergoes different stages of crystallisation, causing it to contract and crystallise in different ways, resulting in cracks. Therefore, it is recommended to cool candles at a steady temperature of 18°C to 25°C for 48 hours. After this period, the candles can be kept at slightly cooler temperatures.
Cracks in candles can be caused by air bubbles in the mixture. To prevent this, tap out any air bubbles before the wax sets. If cracks do occur, they can be filled in with melted wax. Alternatively, a heat gun can be used to smooth out the cracks, although they may reappear as the candle cools.

Candles can be placed in the fridge to harden wax
It is not advisable to place candles in the fridge to harden wax. While it may be tempting to store candles in the refrigerator to keep them cool, this can introduce unwanted moisture. The best temperature to store candles is at room temperature.
Candles have a lifespan and can undergo changes over time. To make your candles last longer, it is recommended to trim their wicks, keep them out of drafts, and put them out correctly. Storing them at room temperature is also essential.
Additionally, it is important to note that the area of wax being burnt will quickly warm up to room temperature, even if the candle is cold. Therefore, the extra effort of putting a candle in the refrigerator is not worth the minimal increase in burn time.
Instead of focusing on storage temperature, it is more crucial to follow proper candle care techniques. This includes trimming the wicks, protecting them from drafts, and ensuring a proper first burn to prevent tunneling. By prioritizing these care practices, you can ensure your candles perform as expected and provide a premium experience.
In summary, while refrigerating candles may seem like a way to harden wax and extend their lifespan, it is not recommended due to the potential for moisture accumulation and the minimal impact on burn time. Proper candle care and storage at room temperature are the best practices to ensure the longevity and quality of your candles.
