I posted about the oven thing in the dripping thread I made in this subforum...
Do em the same way I did 510 attie's, 200F for 10 minutes. Preheat the oven, put your atty in (I use a little tin foil "boat" so it's hanging on the rack) and turn the oven off. After ten you've got a hot little atty that's almost free of all iso smell. If I still smell it I'll put it back in again, have found the LEO's are a little harder to blow out so there's still usually quite a bit of isopropyl in there to evaporate.
It may seem weird but I've never had an atty killed this way, much more likely to pop em during the actual dry burn. And these things get hotter than 200F all the time when I chain
vape, can't be stressing out the components too much. Got one 510 attty I baked for months.
