Yes, the method is exact. I have my own and it's slightly different. I'm also giving an explanation of what's happening during the process
The method should be used just when the atomizer is not performing so well or when you can feel that damn bad taste even after washing it.
Ok so let's also have some atomizer basics. The resistance is wrapped around some fibreglass which, when the atty is new, appears white and has either the function to hold e-
juice on the resistance and to cool it down. After just few milliliters of vaped
juice these liquid getting heated get burned and clolour the fibres in black or dark colour. Most people think the fibres are burned but they are wrong. Is the liquid that is burned, since the fibres should melt at around 2000 °C, temperature not reachable by the resistance which usually runs at 500/600°C. I even tried burning the fibres whith a lighter.. They don't! They get black just because of the gas coming form the flame.
So! Let's get into business.
I'll take a 510 model for the explanation but can be done with every atomizer.
1 Remove cartridge or drip tip, and take out the excess liquid by blowing on the side where you'd attach the cartridge until no more comes out.
2 Put the atomizer under hot water for a minute ( water must flow directly on the bridge side), then you let the atomizer chamber fill with water and quickly blow from that side letting water come out from the battery side at a higher pressure. This will clear the bridge too. Blow on a paper again like step 1 until water stops coming out.
3 Connect the atomizer to your battery, and possibly charged at its maximum.
4 ( Don't insert cartridge or drip tip yet)Now put your mouth on the atomizer again, press the activation button and blow like step 2 for 10 seconds. do this 5 times. This because there might be some resiues of water, you should see them coming out from the atty's air valves. Remove the atomizer and dry the battery and atomizer contact if there's some water on it.
5 Drying: Now press the button and look inside the atomizer away from outside lights until you don't see the resistance turning to orange for two seconds then stop pressing the button and blow in the atty to cool it down and helping drying it.
6 Repeat step 5 from 8 to 10 times. The first times you'll notice it takes more time for the resistance to turn to orange ( don't worry, keep pressing on the button until it gets orange), it will be faster after each activation. It is possible that the first times the resistance will get orange only on the side, but doing it more will let it turn to the colour on the whole length. when the resistance get to orange in 1-2 seconds the drying procedure is complete.
7 Now it comes the REAL DRYBURN which will dissolve all the incrustations of liquid from the resistance and from the fibres.
Now press the button until the resistance get orange and keep it like that from 2 to 5 seconds or ( even less with a LR atty), then wait for the atomizer to cool down. You'll smell some burned stink, that is the incrustation dissolving. Do this 2 times.
8 Repeat from step 2 to step 7. Repeating is part of the method IT MUST BE DONE, this will take away all the reisidues of the incrustations deriving from dryburning.
Repeating will probably take you atomizer to life again getting away that awful burned flavour or improving the atomizer performance since they can decrease in time and most of the cases is for this phenomenon.
