1. Keep the wick trimmed to 1/2cm from the wax at all times.

2.  It is suggested to trim the wick every 4 hours of burn time.

3.  When trimming your wick, you should always extinguish the flame, let the candle come to room temperature and then trim the wick before re-lighting your candle.

4. It's always good practice to trim your wick before lighting your candle each time.

5. Do not let your wick curl otherwise it will result in a big flame, burn the fragrance and rapidly reduce burn time.

#1 When you light a candle for the very first time, be sure to let it burn for a while. You want to ensure the entire surface of the candle melts before you put it out. Why? If you don't, your candle could end up with a rim of solid wax that never ends up melting. (This is called tunneling—and you've probably seen it happen before.)

 

If you want all the wax in your candle to burn, it's important to let it burn evenly before you put it out. This process should take at least 1 hour—so try not to light a new candle unless you have a little time to spare.

​

#2 If you want a clean, even burn, you'll want to make sure your candle's wick is the right length. And doing so might require some trimming. Before you light your candle, double-check your wick's length. If it's longer than the recommended 1/2cm, use scissors (or a wick trimmer) to neatly trim it. Then relight it. Of course, you don't want to cut it too short, either. A too-short wick can get lost in a sea of melted wax and fail to light, so try to be as precise as you can.

​

#3 You should stop using a candle before it completely runs out of wax. Why? If you let your candle burn all the way down, it could overheat its container—which could cause a problem, create a mess, or both. Most candle experts recommend retiring your candle while there's still 0.5 inches of wax left in it.

​

Remember, you can always clean out the wax and reuse your container. Grow light Forever recommends using a mug warmer to burn off the rest of the wax, or placing your candle in the freezer. This can cause the wax to shrink, allowing you to get it out more easily. "Give your vessels another life and reuse them for other purposes—as a flower vase, an orchid pot, a pencil holder, a makeup brush holder, or even a drinking glass,

​

#4 Unfortunately, your candles can expire over time. And while they're unlikely to spoil the same way food does, they can lose their fragrance, become discolored, or otherwise grow stale. Temperature fluctuations can speed the aging process up—and light can, too. So find a cool, dark place to store your candles between seasons. (Grow light recommends storing your candles at room temperature.) And whenever possible, try to light your candles within 12 to 16 months of buying them.

​

Don't put your candle in a windy spot
Wind can cause your candle to burn unevenly, which can lead to tunneling. "Keep the candle away from air vents, windows, or drafts, "If you notice the flame flickering, or it appears to be tunneling, move the candle to a place with less air movement."

​

#5 Have you ever seen a candle wick topped with something that looks like a small burnt piece of popcorn? This is called a mushroom. Be sure to remove mushrooms from your wick before relighting your candle. (Otherwise, you may end up with a very large, smoky flame.) When you go to trim your wick, look for mushrooms and remove them. Then relight your candle.

NEVER LEAVE YOUR CANDLE UNATTENDED!
