My wife would vape her builds until they were so badly gunked up it was almost useless to clean them, that was when I was building her 30 gauge single wire builds. It did get to the point that its easier to rebuild than to dryburn and hassle with cleaning the burnt cootie mess. 30 and 32 gauge wire after time begin to deteriorate, weaken and loose what little strength the wire had by distorting while trying to wick them, 26 and 28 gauge that I use more in my builds is stronger so dryburning took less of a toll. I make and vape claptons now so its a waste to toss a clapton coil considering the work and wire involved in them. I built my wife's claptons(28/32 kanthal) last October, been rewicking it but she still vaping the same coil and now refuses to vape any single wire build. That's why removing the coil out of the RBA and burning separately works well with the more robust clapton coils getting the YUK that has accumulated where the screws are.
I have never dryburned red hot like you see in many videos that does more damage than good, just till the coil glows and the gunk just begins to change color then scrape the gunk off repeating a couple/few times thus cooties fall down into the airflow adding a sickly burnt taste to the next rewick if not totally cleaned out.
Too bad Kanger gave themselves a bad name back when there was so many protank coil problems that have stuck with them till this day. I never had any problems but I rebuilt the PT heads and didn't used stock coils. Most of my RBA's are 2 years old and still in great condition, no stripped screws but a few phillips that are worn and not lost a screw yet....knock on wood.
