Our customers are always curious about how often they should change the wax melts in their wax warmer. We recommend swapping out wax melts whenever you can no longer smell the fragrance when the warmer is 'on'. For some cheaper wax melts, this can be as often as every 5-8 hours of burn time. For luxury, high-end melts (including Waxpops), your wax melts can hold up to 20 hours of fragrance.
'I've been burning my wax melts for 2 weeks and the wax is still in my warmer. Why should I change my melts if the wax is still there?'
GREAT QUESTION. Candles and wax melts work very differently, and it's important to understand the differences between the two products.
When you light a candle, the heat from the flame melts the wax around the wick. The wax quickly evaporates into the air and the 'wax content' of the candle decreases over time. This is why the wax in your candle jar slowly decreases as you keep burning your candle: the heat from the flame causes the wax to evaporate into your home.
Using a wax warmer is a very different process. With an electric wax warmer, you don't have an open flame. Instead, electric wax warmers use an internal heating element or low-watt light bulb to evenly heat the wax melts. Wax warmers don't have flames, which means the wax doesn't get hot enough to completely evaporate. Instead, the warmer heats the wax evenly so the fragrance can be dispersed into your home. This means that while the fragrance is being released, the wax itself will rarely evaporate.
While the wax melts don't 'disappear' or evaporate, the fragrance in them will evaporate over time. Make sure to keep an eye (or nose) on the fragrance levels when your warmer is 'on'. If you can no longer smell the fragrance, it's time to swap out your melts!
