A great candle deserves a great burn. Whether you're lighting your first soy candle or you've been burning them for years, a few simple candle care habits can help your candles last longer, burn more evenly, and produce less soot.
From trimming your wick to preventing candle tunneling, we're covering the essentials of proper candle care, plus a few things worth knowing if you're using a refillable candle.
1. Trim Your Wick Before Every Burn
One of the easiest ways to get a cleaner, more even burn is to keep your candle wick trimmed to approximately ¼ inch.
A wick that's too long can create a larger flame, excess soot, and uneven burning. You might also notice a little mushroom-shaped buildup at the tip of the wick. That's carbon buildup, and trimming it away helps keep your candle burning properly.
Before each burn:
- Let your candle cool completely.
- Trim the wick to approximately ¼ inch using a wick trimmer or scissors.
- Remove any wick trimmings or debris from the wax before lighting.
ReCandle Co. tip: Our soy wax refills arrive with pre-trimmed wicks, so you're ready to go for your first burn. Just remember to trim between burns!
2. Aim for a Full Melt Pool (But Don't Stress About a Little Wax)
When burning your candle, ideally you want the melted wax to reach all the way to the edges of the vessel. This helps promote an even burn and prevents tunneling, where the candle burns down the center and leaves a thick ring of unused wax around the sides.
For best results, give your candle approximately 3-4 hours to develop a full melt pool, especially during the first few burns.
That said, a little unmelted wax around the edges isn't necessarily a problem with refillable candles.
At ReCandle Co., our refills use a firmer wax formulation so they can hold their shape and easily pop out of the vessel when it's time for a replacement. Because of this, some wax may remain along the sides during earlier burns.
As the candle burns down, the flame sits lower inside the vessel, allowing more heat to build up and potentially melt some of that remaining wax.
The bottom line: Aim for a full melt pool, but don't extend your burn beyond four hours trying to achieve one. A little wax around the edges can be normal and may continue melting during later burns.
3. Burn Your Candle for 3-4 Hours at a Time
When it comes to candle care, consistency is key. Lighting your candle for just 15 or 20 minutes at a time may not give the wax enough time to melt evenly, especially during the first few burns.
For ReCandle Co. candles, we recommend aiming for burn sessions of approximately 3–4 hours, without exceeding four hours at a time.
This gives the wax time to develop a melt pool without leaving the candle burning for an extended period.
4. Keep Your Candle Away From Drafts
Where you burn your candle matters more than you might think.
Air movement from open windows, fans, or heating and air conditioning vents can cause the flame to flicker, which may lead to uneven melting and excess soot.
For the best burn:
- Place your candle on a stable, heat-resistant surface.
- Keep it away from drafts, curtains, and anything flammable.
- Keep the wax free of dust, wick trimmings, and other debris.
- Never leave a burning candle unattended or within reach of children or pets.
- Allow your candle to cool completely before moving or handling it.
A steady flame helps your candle burn more consistently, and following these basic precautions helps keep your candle-burning routine safe.
5. Know When It's Time to Stop Burning
As tempting as it might be to use every last bit of wax, it's important to know when your candle has reached the end of its life.
Stop burning when approximately ¼ inch of wax remains at the bottom of the vessel. Continuing to burn beyond this point can cause the vessel to become excessively hot.
If you're using a traditional candle, that usually means it's time for a new one. But if you're using a ReCandle Co. refillable candle, it's time for the fun part: swapping in your next candle refill!
Our specially formulated soy wax is designed to release from the vessel once it has completely cooled, allowing you to remove the finished refill and replace it with a fresh one.
No need to throw away a perfectly good candle jar.

Common Candle Care Questions
Even with the best candle care routine, you might notice something unexpected while your candle burns. Here are answers to a few common questions.
Why Is There Wax Left Around the Sides of My Candle?
A little unmelted wax around the sides doesn't always mean your candle is tunneling.
With traditional candles, repeated short burns can create a narrow tunnel through the center of the wax. But with ReCandle Co. refills, our firmer wax formulation can also leave some wax around the edges during normal burning.
As the candle burns lower in the vessel, some of that remaining wax may melt into the wax pool. However, if your candle consistently burns down the center without melting much of the surrounding wax, it may need troubleshooting.
For a closer look at the difference, read our guide to candle tunneling and how to prevent it.
Should I Use Aluminum Foil to Fix Candle Tunneling?
You may have seen the aluminum foil trick for fixing a tunneled candle, but we don't recommend wrapping foil around your ReCandle Co. vessel.
Foil can change how heat builds up around the candle and may cause the vessel or wax to overheat.
Instead, stick to normal burn sessions of up to four hours and allow your candle to cool completely between burns. If the wax continues to burn unevenly, reach out to us so we can help you troubleshoot.
How Long Should a Soy Candle Last?
Burn time varies depending on the candle's size, wax formulation, fragrance, and how it's cared for.
At ReCandle Co., our soy wax candle refills are designed to provide approximately 40 hours of burn time, giving you plenty of time to enjoy your favorite scent.
Keep in mind that burn times are estimates, not guarantees. Factors like wick length, drafts, fragrance, and how long you burn your candle during each session can all affect how quickly the wax is consumed.
For the longest, cleanest burn possible, follow the candle care tips above, especially trimming your wick regularly and keeping burn sessions to 3–4 hours.
Why Is My Candle Producing Black Smoke or Soot?
A small amount of smoke when you extinguish a candle can be normal, but persistent smoking or visible soot while burning is a sign that something may need adjusting.
A wick that's too long, a drafty location, or an excessively large flame can all contribute to soot buildup.
Extinguish the candle, let it cool, trim the wick to approximately ¼ inch, and make sure it's positioned away from moving air before relighting.
If your candle continues to produce excessive smoke, stop using it and contact the manufacturer.
When Should I Replace My ReCandle Co. Candle Refill?
Once approximately ¼ inch of wax remains at the bottom, it's time to stop burning and prepare for your next refill.
Allow your candle and vessel to cool completely before attempting to remove the remaining wax. Never try to remove a refill while the vessel or wax is still warm.
With ReCandle Co., you can keep your reusable vessel and simply replace the wax insert with a new scent. Browse our soy candle refills whenever you're ready for your next one.
Better Candle Care, Better Burns
Good candle care doesn't have to be complicated. Trim your wick, give your candle enough time to burn, keep it away from drafts, and know when it's time to extinguish the flame.
Whether you're enjoying a traditional soy candle or making the switch to a refillable one, these simple habits can help you get more enjoyment out of every burn.
And remember, candles don't always burn exactly the same way. A little wax along the edges or a slightly different melt pool isn't necessarily cause for concern.
