In my opinion, the only way to really enjoy eSmoking to the fullest extent is to drip. When I bought my first e-cigs and one small 4ml bottle of
e-liquid, I would use a syringe and slowly fill my cartridge until moistened. Then I would leave the cartridge upside-down for 10 minutes to make sure the wool in the cartridge had completely saturated the added liquid. I never dripped on the atomizer at first.
When my small 4ml bottle was gone. I didn't like E-smoking without it. I needed that extra punch, even with new cartridges. So I smoked real cigs (just a couple) until my new
e-liquid arrived.
When I became a pro at filling carts, I started dripping on the atomizer itself, but never more than one to two drops, which equals maybe one cigarette's worth of smoking. That way I only had to clean/blow out my atomizers once per week.
Also, it depends on the brand of e-cig you are using. Some do not take well to dripping; others do. You soon find out through trial and error. My Sedansas can withstand a lot of dripping and topping off. They do eventually clog up if done too much and too often, but all I do is blow them out.
Also, if you use some of the fruity-flavored
e-liquids -- pinapple for one -- it really clogs the atomizer and sometimes kills it. If you do end up with a permanently clogged atomizer, soak it in hot soapy water or white vinegar and water in a covered container for an hour, rinse well, blow out residual water, then let dry upside-down at an angle in the hot sun or with a hair dryer.
