Whether or not you need to discard the melted wax after using a scented candle depends on the specific circumstances. Here are some detailed recommendations:
1. When Discarding Wax is Not Necessary
- Normal Use: If the candle still has a lot of unburned wax (such as when it's just been used for the first time or has only burned for 1-2 hours), there's no need to discard the wax. The wax will solidify again after cooling and can be used again the next time you light it.
- Avoid Waste: Discarding unused wax shortens the lifespan of the candle, especially for high-quality scented candles, which are more expensive. It's recommended to burn the candle thoroughly.
2. When Wax Cleaning is Necessary
- When the Candle is Nearing Burnout: When there's very little wax left (less than 5mm) or the wick won't re-ignite, discard the remaining wax, clean the container, and reuse it.
- Abnormal Candle Burning:
- Tunneling (deep pit in the middle): If a large amount of unburned wax remains around the wax pool, discard some of the surface wax, leaving about 1cm of wax around the wick. This can be corrected the next time you burn it (making sure to burn it long enough for
the wax to melt completely to the edges). - Trash or debris: If there are dust, wick fragments, etc. in the wax, you can filter and remove them while it's still hot, but generally, you don't need to discard all of it.
3. Tips for Extending Candle Life
- First Burn: Ensure the wax pool is completely melted to the edges during the first burn (usually 2-4 hours) to avoid the formation of memory rings.
- Trimming the Wick: Trim the wick to about 5mm before each use to prevent black smoke and overheating of the wax.
- Avoid Blowing Out: Use a cap or wick cutter to extinguish the candle to reduce smoke and splatter.
4. Safety Precautions
- Do not pour hot wax directly: High-temperature wax can cause burns. Cool it until it solidifies or use a tool (such as a cotton swab) to clean it.
- Reusing the Container: If you want to keep the container, freeze the candle to shrink and release the wax, or melt any remaining wax with hot water for cleaning.
In short,
- It's not necessary to discard the wax every time; keep it during normal use.
- It's only necessary to clean the wax when the candle burns out or to correct a burning problem. - Proper use and maintenance are more important than frequent cleaning to maximize the effect and life of the scented candle.
