Couple of months ago, when I started vaping, one of my questions was, "Should I dry burn?" I Googled it and read conflicting views.
Those who do not recommend dry burning gave these reasons :
1) You'll burn your wick.
2) You'll pop the coil.
3) Clearos are meant to be disposables.
4) Not worth the effort.
5) Burnt taste after dry burning.
Here's my opinion:
1) Silica wick will not burn or char. Proper way to torch the Silica Wick to restore it ... - YouTube
2) Haven't had that happen yet, even setting the voltage to 4.2V. I'm not saying it won't. But I think it will only happen if you get mesmerized by the glowing coils.
3) Can't argue with that, but I'm a cheapo.
It's also kind of difficult to get ecig stuff where I come from.
4) Not much effort required. Unless you consider pressing a button an effort.
5) The burnt taste probably comes from the ashes on the coil or wick which wasn't rinsed off. Many youtube tutorials fail to mention that you have to RINSE after dry burning.
Things to note :
A) Dry burn while the wicks are still damp from rinsing. (Maybe I should call it wet burn?)
The water will heat up and help get the gunk off the wick. The coil cleans easily, but the areas of the wick which do not touch the coils are more difficult to clean. That is why I dry burn after 1 or 2 tanks to prevent gunk from building on the wicks, not the coil.
If the wicks still look black after dry burning, add a couple of drops of water to the wick and burn again. Vodka or vinegar would probably clean it better, but I have not tried them. As I said, I'm a cheapo, so I would rather drink the vodka. Personally, at this point I toss the clearo.
B) If you're using CE4s (base cannot be detached), let the tube cool between each burn. You can also use a damp cloth and wrap it round the CE4 to keep it cool during dry burning. Or you can blow into the tube while dry burning, BUT do not be too enthusiastic. You might pop the coil if it's already glowing red hot.
C) The coils and wick look dirter/gunkier when wet. You'll see the difference when they dry.
D) RINSE! RINSE! RINSE and air dry it before using.
Here's a picture of Kanger T3 heads before and after dry burning. I have 5 of these heads and have been using them for about 3 months. I dry burn after about 2 tanks (I vape about 1.5 tank a day). Note that the coils are the original coils.

I hope that this can help newbies with the same question I had.
