The First Burn: Why It's the Most Important One
The single most impactful thing you can do for a soy candle happens the first time you light it. Soy wax has memory — it follows the pattern set by the first melt pool, and if that pool doesn't reach the edges of the container, the candle will tunnel down the center for its entire life.
Tunneling is the most common candle complaint, and it's almost always caused by an interrupted first burn. The fix is straightforward: on the very first burn, let the wax melt all the way to the rim before you extinguish it. This typically takes 2–4 hours depending on the vessel diameter — a wider container needs more time.
The first burn sets the wax memory for the life of the candle. A full melt pool on burn one means a full melt pool on every burn after.
What you're watching for: a liquid wax pool that reaches the glass or tin edge all the way around, with no dry ring of solid wax. Once you see that, the candle is set. Every subsequent burn will follow the same pattern.
If you do get tunneling — say the candle was already burned this way before you read this — you can partially recover it. Wrap the top of the candle in aluminum foil, leaving a small opening at the center for the wick. The reflected heat will melt down the wax walls and level the pool. It takes patience, but it works on most tunneled candles.
Wick Trimming: 1/4 Inch, Every Time
Trim the wick to 1/4 inch before every single burn. Not just the first burn. Every burn.
This is the rule most people skip — and skipping it is why you get a large, flickering flame, black soot on the glass, mushrooming carbon buildup on the wick tip, and a candle that burns through wax too fast. An untrimmed wick also produces more smoke when extinguished.
Trim to 1/4 inch before every burn
Use a wick trimmer, nail clippers, or sharp scissors. Do it before lighting, not after. Trimming a still-warm wick is messier and less accurate. Let the candle cool fully between burns, then trim before the next use.
What a proper flame looks like
A correctly trimmed wick burns with a steady, teardrop-shaped flame about 1–1.5 inches tall. It shouldn't flicker excessively, smoke, or produce a large flame. If you see any of those, the wick needs trimming.
If you see a mushroom tip, trim it off
Carbon buildup on the wick tip — the "mushroom" — happens when the wick is too long. It causes uneven burning and soot. Extinguish the candle, let it cool fully, then trim below the mushroom before relighting.
Cotton wicks — which WickAndWash uses in all candles — are designed to curl slightly as they burn. This is intentional: the curl moves the tip into the cooler part of the flame, which helps with self-trimming. But they still need manual trimming between burns. The cotton wick does the work during burning; you do the work before.
Burn Time Limits: 3–4 Hours Maximum
Keep burns to 3–4 hours maximum per session. This applies to all soy candles, regardless of size.
Beyond 4 hours, the wick starts to "float" as the wax pool deepens — it becomes destabilized and produces a larger, more irregular flame. The wax also gets very hot, which can stress the glass or tin and, in the worst case, cause it to crack. Fragrance throw degrades at very high temperatures too — the scent that was so good in the first two hours becomes unpleasant or disappears entirely when the wax is overheated.
3–4 hours is the right window. Long enough to enjoy the full scent throw. Short enough to keep the burn clean, the flame stable, and the vessel intact.
There's also a practical burn life benefit. A candle burned in controlled 3–4 hour sessions will outlast the same candle burned in long 6–8 hour marathons. The wax is consumed more efficiently at moderate heat, and the wick stays in better condition. A 50-hour WickAndWash candle burned correctly will actually hit close to 50 hours. Burned carelessly, that same candle might give you 30.
Always extinguish the candle with a snuffer rather than blowing it out. Blowing creates a smoke plume that lingers in the room and pulls the wick off-center. A snuffer — or simply placing the lid over the flame — eliminates the smoke and keeps the wick positioned straight for the next burn.

Storage: Keep Soy Wax Away from Heat and Sunlight
Soy wax is more temperature-sensitive than paraffin — it's one of its strengths (cleaner burn, no petroleum) and one of the things that requires a bit of care in storage.
Store soy candles away from direct sunlight and heat sources. A windowsill in Florida in July is not a good place for a soy candle — even for a few days. Direct sun exposure will cause the wax to soften, pool, and potentially discolor. The fragrance will degrade faster too. A drawer, cabinet, or shaded shelf is the right home for a candle you're not currently burning.
Ideal storage temperature: 65–75°F
Room temperature is fine. The risk zone is heat: a car in summer, a sunny windowsill, next to a heat vent, on top of a radiator. Below 60°F, soy wax can get brittle and develop surface cracks — they don't affect burn quality, but they look odd.
Use the lid between burns
The lid keeps dust off the wax surface (which would soot when burned) and slows fragrance loss when the candle isn't in use. It also keeps the wick upright and centered. Put it on every time the candle cools after use.
Keep the original packaging for long-term storage
If you're gifting or storing a candle for more than a few weeks, the original box is the best protection. It blocks light, insulates against temperature swings, and protects the vessel from knocks.
How Long Do Soy Candles Last?
The answer depends on the candle size and how carefully it's burned. A well-made soy candle will advertise burn hours — WickAndWash candles are rated for approximately 50 hours — and those numbers are achievable when the care rules above are followed.
Here's what actually determines burn life:
| Factor | Correct approach | What goes wrong |
|---|---|---|
| Wick trimming | 1/4 inch before every burn | Long wick burns wax faster, reduces total hours |
| Burn session length | 3–4 hours maximum | 6+ hour burns overheat wax, reduce total hours |
| First burn | Full melt pool to the edges | Tunneling wastes wax trapped in walls |
| Storage | Cool, dark, lidded between burns | Sun/heat degrades fragrance, shortens perceived life |
| Extinguishing | Snuffer or lid | Blowing out creates smoke, displaces wick |
It's also worth knowing that soy candles have a shelf life of roughly 12–18 months from the pour date for full fragrance performance. The wax itself lasts longer, but essential oil fragrance does fade over time even in an unlit candle. WickAndWash candles are made in small batches specifically so they're always fresh — no warehouse inventory sitting for 2 years before reaching you.
Why Soy Wax Behaves Differently Than Paraffin
If you're switching to soy candles from paraffin (the mass-market default), a few things will look different and shouldn't cause alarm.
Frosting is a white, crystalline coating that sometimes appears on the surface or sides of soy candles. It looks like it might be a flaw — it isn't. It's a natural property of natural soy wax and a sign that it hasn't been blended with paraffin or chemical stabilizers. It doesn't affect the burn or the scent. Paraffin candles don't frost because they're petroleum-based and chemically stabilized.
Wet spots — areas where the wax appears to have pulled away from the glass — are also normal in soy candles. They happen when the wax contracts during cooling and adheres unevenly to the glass. Again, not a defect. The candle burns identically.
Softer wax is characteristic of soy. At room temperature, a soy candle is noticeably softer than paraffin — you can press into it with a fingernail easily. This is because soy has a lower melting point (~120°F vs. ~145°F for paraffin), which is part of why it burns cooler and cleaner. It also means the candle is more sensitive to heat in storage, which is why the storage rules above matter more for soy than for paraffin.
