I always dry burn my attys after cleaning and it has brought otherwise lifeless attys back to life and prolonged the useable life and performance of all of them, you do have to be careful and not over do it. I haven't popped one yet but I'm sure it be done fairly easily if one went to far with it.
Dry burning burns all the build up off the
coils and wick around the
coils. You can soak an atty all you want and that's great for getting liquid and most of the stuff out but it won't get rid of what's baked on to the coil which when built up enough keeps the coil from heating up the liquid enough. It has to be cooked off which is what dry burning does.
Here's a video using a CE2, its the same principal for a atty though.. He a little braver doing it that I am. I usually stop when everything is clean but it's the same procedure and it does show everything very well starting at about the 5 minute mark.
