Condom refill method questions
I've been refilling cartomizers for about a year now, and I usually use the syringe method (Sharpies work best for me because I can slip them all the way down to the bottom to ensure the wick around the atomizer is saturated, but blunts are all I can find these days). If I'm filling only one or two carts, usually to test a flavor, I just use the drip method.
But I have some carts from a vendor I no longer use that have non-removable caps -- actually they are not even caps, they appear to be made as a single piece. So I thought I would try the condom method to refill them with Vapor4Life juice. I watched a couple of videos, followed the instructions and managed not to make a mess. So far, so good. But now I have a couple of questions.
1 - There is liquid remaining in the central post that burbles when I inhale. (I let them stand upright for more than a half-hour before attaching, and nothing drained out.) Using my usual methods, I avoid getting liquid in the central post, and if a drop gets in accidentally I blow it out right away. After using the condom method, should I have blown out the central hole? In the videos I've seen, when the cart is filled they just wipe off the threaded end, attach it and start vaping away. Will vaping them with liquid in the center cause damage?
2 - Is there any way to clean these after a few refills if the cap is not removable? It's hard for me to see how I could get enough hot water going through them to get them clean. Is there another way, or should I just figure on tossing them after a few refills?
3 - Not related specifically to condom refill, but how many times do people refill cartos before cleaning them? I've found with each refill, the carto holds less and so lasts for shorter and shorter times, so I've gotten into the habit of cleaning them after every two refills. Does frequent cleaning affect the life of the cartridge, either good or bad? I've been getting probably 20 or 30 refills from a cart, but they seem to be less flavorful after 10 or so.
Thanks for any insights!
