I have been experimenting with cleaning my boge cartomizers with mixed results. They NEVER taste as good as a fresh one, but I've had some pretty good results. I put them in a turkey baster, (saw the utube video) and rinse it 3 or 4 times with lukewarm water, suck in, out, repeat a few times. I add about 10 drops of alcohol, don't know if this is a good idea, but it seems to get rid of residual flavors. Then I blow it out. I have a small desk fan and I literally stick it in the fan - I can do it where the fan blades do not hit the cartomizer but it gets blown on. I usually let go for 24 hours as I have no idea how long it takes to truly dry out. Some of them taste ALMOST NEW, SOME taste ok, and some I have to toss, because somehow in the process they "broke".
I always test it with some
juice that is not expensive (but still good to start with) so that if it is one that didn't work I haven't lost $$$. But there are a lot of great deals on cartomizers so I really prefer to use a fresh one. I think I am doing this more out of curiousity than anything else, but it is pretty neat when I load one up and I can barely taste the difference between it and a virgin one.
I tend to drip lots of different juices, I am not a one
juice person, so I suspect the outcome may have something to do with which juices I used. I haven't figured that part out yet, just a gut feeling.
