Sounds like overkill to me but if it works, it works.
On the topic of boiling, I've been alternating 2x 901 attys and a 510 atty for the month and a half I've been vaping.
Out of those three the 510 and one of the 901's are still going like new (with once a week blow-outs)
The other 901 suddenly dropped to 10% perfomance. By that I mean....when i hold a primed atty to my ear with a manual battery, I hear a nice loud hiss/crackle. This thing would go..."pop....crack................pop" and emit tiny amounts of vapour.
A mate I hooked up with a 901 kit and spares has had 2 901 attys die on him (I'm assuming user error) and he lost track of one.
He gave me his other dead 901 atty and I boiled it with the one I had limping at 10% (boiled a good 3-4 mins) After letting them cool, blew them out, drained overnight, primed them, hitched em up to a battery.
And both are functioning exactly as they were before boiling. My mates totally dead atty is still totally dead, and mine is still producing a pitiful amount of vapour.
It might also be worth mentioning that there wasnt a single grain of visible residue left in the pot. I'm guessing something other than gunk buildup killed these attys.
Any other possibilities?
