Clean Smoke on the other hand is usually light blue and only slightly visible. You’re still getting all the benefits of cooking with a natural fuel source, such as charcoal or wood, you just aren’t getting all the dirty smoke. Clean Smoke comes from a fire that has already been lit and has had a chance to stabilize.
One could say that clean smoke comes after the dirty smoke has burned off. Clean smoke is effective, but boring.
Of course when adding more fuel and/or stoking a clean, burning fire, you will get active smoke rising for a short while. This is not a bad thing. It just means that the fuel you added is going through the process of Dirty to Clean.
