You must regularly take care of your e-cigarette to maintain its performance and to use it sustainably. The procedure is quite simple.
Maintain systematically the clearomizer when charging e-liquid or the change of the resistance. Specifically, you use a canvas microfibre cloth dipped in water to wipe down the atomizer ;
You use a toothbrush to scrub the mouthpiece or drip-tip, to remove all the dirt.
Also clean the battery with your cloth dampened.
Finally, you go up to the resistance and the whole device.
