If I went through as many wash/rinse/spin cycles as I see some people doing I probably wouldn't bother cleaning them either. When I clean:
Step 1: Dry burn it. No soaking in this then soaking in that. Remove the vent tube, leave the top wick in place, and just start burning.
Step 2: Once the gunk starts burning off and smoking then remove the top wicks. It just makes the whole process easier to even see the difference between them and the top coil, and remove them as well. Once removed it takes only a couple seconds to burn the gunk off the top wicks running them through a gas flame. If the top wicks are too far gone/frayed just replace 'em.
Step 3: Finish your dry burn of the coil - and you aren't done until is stops producing nasty smoke.
Step 4: Leave the coil on the base and put it in some simmering water for all of maybe 2 minutes to get any ash out of the wick and coil from the dry burn. Put it in the simmering water Ego threading down - that forces water to percolate from the base through the coil/wick. While you are at it throw the metal vent tube in there as well to clean that too. When it's cool blow any water you can out of it.
Step 5: Dry burn off any water that's in the wick. If you did your real dry burn right you'll get some steam out of it until dry, but no additional nasty smoke odor. This part isn't really even necessary, but it confirms for me that all the gunk is really gone if this quickee burn to get the water out doesn't produce more gross smelling smoke. And it just dries everything out. Put the top wick back in and reinstall the vent tube. Done.
Five minutes, tops, largely depending on how long it takes to completely dry burn the coil in step 3. No vodka, everclear any any other type of alcohol required. And no soaking - period.
One reason I prefer to dry burn rather than replace the coils every time is because I don't want to be removing that little rubber grommet very often. I can't find a suitable replacement, and every time you take them out you are putting wear and tear on them. In my mind, that's the piece that's going to limit the lifespan of a head. Dry burning for me is quick and easy, and IMO restores the coil to as good as new. I like my coils to be fresh and replacing them every time I was dissatisfied with the vape would get expensive. Here's how I do it.
Take the tank off, remove tank part and set aside.
Put head and base under hot running water while I get the rest of the stuff out. (Small pliers, 1 mm wick, nail clippers)
Use pliers to remove top stem.
Take off flavor wicks. If they look good, I set them aside to reuse. If they look too dirty I toss them.
Blot base and stem dry, and put on ecig.
Pulse battery until coils are glowing evenly and funky smoke disappears.
Remove head from base and put in a bottle of water. Shake through 2-3 rinses of water. Blot dry.
Put flavor wicks back on, or add new ones. Replace stem. Reassemble tank. Vape.
Just for kicks, I just timed myself. Took me 2 minutes and 37 seconds. Lol. I reused the flavor wicks. If I'd added new ones it would have added a little more time.
