Very helpful video, although I wouldn't dunk it in water while still on the mod, and I know he says he's not a heavy user, only 30 ml a day, and well, I must be a real lightweight at 6-7 ml a day, and not all the same tank. If I vaped that much I'd be dry burning every day too.
My quick wash up. Both rta and rda.
Take it off the mod. Pop the deck out or whatever, pull the old cotton out and toss it. Run the base and coils under hot water. Gets rid of the surface crap which means less to burn off.
Place it on my 521 tab or mod. I use SS almost exclusively so I keep gently pulsing. At first it's mostly just evaporating off the water from the rinse, then as they get orange, the crappy stuff. Go with short pulses until it's looking sorta good.
Take it off and rinse again in warm water. This gets rid of the ash that may fall off onto the bottom of the deck. Go over it with my glasses on and so a little scrubbing with the tiny dental pick thingy. That includes the grub heads and posts. I like all the metal to look clean. Dry it with a paper towel after a good shake off. Remount it on my tab (or mod or whatever) and if it looks good rewick.
If it still looks cruddy, and not the color the coil rarely will get back to its original appearance just as a result of the changes that happen with heating, but if I still see little bits or tiny crusty areas still there I mount new coils.
I get about 3-4 months out of fused Claptons that way. Even more if it's an occasional use tank.
All that does take me an extra 2-3 minutes than just slapping fresh cotton on, but it's worth the effort as iit tastes essentially brand new when I'm done.
You can use any variation on that, but that voodoo ritual has worked well for me, and I haven't had to sacrifice a chicken in years to beg for a clean tasting vape.
