The Truth About Candle Care: How to Stop Tunnelling and Soot

Lighting a candle should be simple: strike a match, relax, and enjoy the fragrance filling your home.

But sometimes candles behave in ways we don’t expect tunnelling, uneven burns, or even a little soot around the jar. The good news? These issues are usually easy to prevent with a few simple candle care habits.

Here’s how to get the best burn, strongest scent, and longest life from your candle.

What Is Candle Tunnelling?

Candle tunnelling happens when the wax melts straight down the centre of the candle, leaving a ring of unused wax around the sides.

Not only does it waste wax, but it also shortens the life of your candle.

The main cause? Not letting the candle burn long enough the first time.

How to Prevent Candle Tunnelling

The first burn is the most important.

When lighting your candle for the first time, allow the wax to melt all the way to the edges of the jar. This usually takes 2–3 hours depending on the candle size.

This creates a full melt pool and “sets the memory” of the wax so it burns evenly in the future.

Simple rule:
👉 Burn your candle long enough for the whole surface to melt.

Trim the Wick (It Really Matters)

Before lighting your candle each time, trim the wick to around 5mm.

A wick that is too long can cause:

• Excess smoke
• Soot marks on the jar
• A larger flame than intended
• Faster burning

Keeping the wick trimmed helps the candle burn cleanly and evenly.

Avoid Drafts

Burning candles near open windows, fans, or air vents can cause:

• Flickering flames
• Uneven melting
• Increased soot

Place your candle somewhere stable and away from strong airflow to ensure the best burn.

Don’t Burn for Too Long

While candles love a good first burn, it’s best not to burn them for more than 3–4 hours at a time.

This prevents the wick from becoming too hot and keeps the fragrance performing beautifully.

A Little Care Goes a Long Way

With a few simple habits, your candle will:

✨ Burn evenly
✨ Last longer
✨ Smell better
✨ Look beautiful throughout its life

Candle care might sound technical, but really it’s just about giving your candle the best conditions to shine.
