I only run 3 to 4 ml. of liquid through a new carto. I then fill it with plain VG or PG, put condoms on it and set it aside to await "cleaning day". (I've found plain VG and PG are good at loosening the gunk on the coil). I would say I lose one out of ten after cleaning. The other 9 work well and after another 3-4 ml. of liquid... I clean them again. I repeat until they die.
Here is a video. If you jump to 6:57 it will explain and show you a quick cleaning method using a turkey baster. You can then put them in the oven on a oven safe plate for drying. About 170° for 1 hr. Turn oven off and leave over night.
I used to use this method, but lately I've been using this cleaning kit, using a high proof vodka last rinse. I just put the vodka in a cleaned out, small prescription bottle and pull and push it through the carto a few times using baster or kit. Works quite well, and they dry overnight sitting battery side down on a paper towel... no oven needed.
Turkey baster, or carto cleaning kit... I find it's the high proof vodka rinse which evaporates that leaves the carto dry within 24 hrs. YMMV.
Hope this helps.
