I have the Kangertech Subox Mini and I use the pre-made coils that you buy and just drop in. I am also a member on a Facebook group for vaping and some of them were saying there are ways to clean your coils and use them again. I know there's some gurus in here so I felt this would be the best place to ask. Is this true? If so, how would you go about it?
This post is basically the same as what
@Topwater Elvis said but includes some why. As a result it is vastly longer though the effect is the same.
Yes, kind of, but not really and not well. There are a bunch of ways folks used to clean old fashioned bridged atomizers back in the day but the cotton wrap and o-rings in the coil cartridge kills most of them.
One was a sonic cleaner which won’t work because the coil head contains not only cotton but rubber which will dampen the vibrations
Another is denture tablets which also won’t work because it will make the cotton taste like donkey doodle.
Boiling in distilled water (NOT tap water) might possibly work, but it never worked very well, and all it does is loosen the cruft anyway so you still need a way to scrub it, at which point you run into the cotton.
@Topwater Elvis ‘s suggestion seems to be a more advanced form of this one. He’s using a PG soak instead of hot water which should shorten drying time by like a week and cause a lot less flavor damage to the cotton. He’s also not using a pipe cleaner to scrub the inside of the coil which implies that’s a bad idea in this case anyway. I’ve never boiled a modern coil cartridge so there may be other problems with the cotton as well.
The last option I know of is to soak in really high strength ethanol. I used everclear for this myself. I still got a gigantic mostly empty bottle of everclear lying around somewhere. It’s the only alcohol in my house and tends to cause comments. It didn’t really work any better than the distilled water boil though.
You might be able to get a result using multiple layered methods but the amount of sheer labor makes it totally pointless. It could possibly be worth it if and only if getting new coils is impossible, but it’s still probably cheaper to buy a whole new tank if you include labor cost.
IF your particular cartridge uses silica instead of cotton (some pods are doing this again. Silica wick got dropped years ago because of silicosis danger). the alcohol method followed by dryburning (you can dry burn silica a bit) does kinda work. That’s how I used up most of a 2 liter of everclear. I was doing EVOD cartridges (the little tiny ones) until they dropped in price from $5 to less than a dollar.
