and this is why I got some RTA's too much trouble cleaning ... its easier to dry burn the coil and rewick
That's no longer an option for my RTAs. You can't dry burn a nickel coil.
Well, you can, but it can damage the coil and releases toxic fumes. You SHOULDN'T dry burn a nickel coil. But then again, with temperature control coils you don't get the caked on carbon residue that you get with kanthal, so dry burning isn't necessary anyways.
As for my premade coils, I soak those in distilled water for a day or so and then let air dry for a week. It usually extends the life of the coil by another 50% before I throw them away, but considering how cheap they are and the fact that most of my premade coils last a month or more before the cleaning, it doesn't bother me to throw them away. Seems kind of silly to worry about a $2 coil when I spend over $2,000 on car tires every year.
