Candles are a timeless favorite, bringing ambiance, fragrance, and warmth to any space. But if you’ve ever found an old candle in the back of a cabinet, you might wonder: can candles expire? The answer isn’t as straightforward as a yes or no. While candles don’t necessarily “go bad” like food, their quality can degrade over time. Let’s dive into the details of do candles expire, how do candles run out, and how to maximize their lifespan.
Do Candles Expire?
Technically, candles don’t have an expiration date like perishable goods, but their wax, fragrance, and wicks can deteriorate with time. Factors like exposure to air, temperature changes, and light can affect a candle’s performance. Here’s what to look out for:
-
Scent Fading: Over time, fragrance oils in scented candles can evaporate, leaving your once-aromatic candle scentless.
-
Wax Discoloration: Natural waxes like soy and beeswax can develop a yellowish tint or appear cloudy due to oxidation.
-
Cracked or Sweating Wax: Improper storage can cause wax to dry out and crack, or, conversely, release fragrance oils, making the candle appear sweaty.
-
Wick Issues: Cotton wicks can become brittle, while wooden wicks may lose their ability to burn properly.
How Do Candles Run Out?
Candles burn because the wick absorbs melted wax, which then vaporizes and combusts. Over time, this process depletes the wax and wick, leading to the candle burning out completely. However, improper burning habits can cause candles to run out unevenly. How do candles lose wax? The answer lies in:
-
Tunneling: If a candle isn’t burned long enough for the wax pool to reach the edges, the wick burrows down, leaving unused wax along the sides.
-
Soot Build-up: Burning a candle in a drafty area or failing to trim the wick can lead to excessive soot, impacting wax consumption.
-
Uneven Melting: Placing candles on an uneven surface or exposing them to varying temperatures can cause wax to melt improperly.
How to Make Candles Last Longer
To keep your candles in top condition for as long as possible, follow these tips:
-
Store in a Cool, Dark Place: Heat and light can degrade the wax and fragrance over time.
-
Keep Lids On: This prevents dust accumulation and helps retain the scent.
-
Trim the Wick: Keep the wick at 1/4 inch to ensure a steady, even burn and avoid excessive soot.
-
Burn Candles Long Enough: Let the wax pool reach the edges before extinguishing to prevent tunneling.
-
Rotate Your Candles: If you have a collection, use older candles first to enjoy them at their peak performance.
When to Toss an Old Candle
If a candle refuses to stay lit, produces excessive soot, or lacks any fragrance, it might be time to repurpose or dispose of it. Old wax can be melted down to create new candles, used as wax melts, or even repurposed for waterproofing items.
