Tips for Burning Soy Candles to Avoid Black Smoke and Soot


Soy candles have gained popularity due to their eco-friendly nature and clean burn. However, improper burning techniques can lead to the formation of black smoke and soot, detracting from the overall experience. To help you get the most out of your soy candles, we have compiled a list of essential tips to prevent black smoke and soot formation. By following these guidelines, you can ensure a cleaner and longer-lasting burn while enjoying the soothing ambiance of your soy candles.

1. Trim the Wick:

Before lighting your soy candle, always trim the wick to approximately 1/4 inch. A longer wick can cause the flame to burn too hot, leading to excess smoke and soot. Trimming the wick helps maintain a controlled flame and minimizes the production of black smoke.

2. Use the Right Size Wick:

Ensure that your soy candle has the appropriate wick size. A wick that is too small may not create a sufficient flame, resulting in incomplete wax melting and the formation of excess soot. On the other hand, a wick that is too large can lead to an oversized flame, causing black smoke. Refer to the candle manufacturer's guidelines for the correct wick size.

3. Let it Pool:

To avoid tunneling, allow your soy candle to create a melt pool that reaches the edge of the container before extinguishing it. This process usually takes one hour per inch of the candle's diameter. Allowing the soy wax to melt evenly ensures a clean and complete burn, reducing the chances of black smoke and soot formation.

4. Avoid Drafts:

When burning your soy candle, keep it away from drafts or areas with air currents. Drafts can cause the flame to flicker and dance, leading to an uneven burn and soot buildup. Choose a stable location where the candle can burn undisturbed to maintain a clean and consistent burn.

5. Burn for an Appropriate Duration:

It is important to burn your soy candle for an appropriate duration to prevent the formation of black smoke and soot. A general rule of thumb is to burn the candle for one hour for every inch of its diameter. This ensures that the wax melts evenly and avoids excessive soot buildup.

6. Extinguish with Care:

When extinguishing your soy candle, avoid blowing out the flame. Instead, use a candle snuffer or gently dip the wick into the melted wax and then straighten it again. Blowing out the candle can produce smoke and disturb the wax, leading to soot formation.

7. Keep the Candle Clean:

Regularly clean the container of your soy candle to remove any soot buildup. Use a damp cloth or paper towel to wipe away any residue. Keeping the container clean not only enhances the aesthetic appeal but also prevents excess soot from being released into the air when the candle is lit.


By following these tips, you can enjoy a clean and soot-free burn when using soy candles. Proper wick trimming, using the right size wick, allowing the candle to pool, avoiding drafts, burning for an appropriate duration, extinguishing with care, and keeping the candle clean are essential practices to ensure a pleasant and long-lasting candle experience. Embrace these tips and create a serene ambiance while avoiding the negative effects of black smoke and soot.

Enjoy the clean burn of Soy Candles!
