If you are asking how I do maintenance on my e-cig, at night I remove the atomizer from the battery, take out the cartridge and place my atomizer in a glass with the cartridge side down so if any liquid is left in it - it will drain over night. I also inspect my atomizer for loose fibres. If there are any I use tweezers to remove them.
If my atomizer stops producing the amount of smoke I am use to and the above didn't help, I will run my atomizer under hot water for a couple of minutes - blow out as much water as I can and place it back on the battery, put a mouthpiece on it and suck on it until I know it is dry. Then I remove the mouthpiece and I drip a couple of drops of
e-liquid into the atomizer until it begins to smoke again. Then I put back in the cartridge.
Does this make sense?
