Kate,
Sorry about the paint-job on your atomizer. I think i remember reading somewhere that isopropyl stripped one of your janty classic atomizers.
That really sucks, and it sucks doubly so because i am quickly finding that this isopropyl method actually works.
I have two dse 901b atomizers. I'm now on about... oh say 2 weeks on these atomizers. They were getting pretty wimpy and honestly i would have probably tossed them if i hadn't cleaned them with isopropyl.
One of them also had a burnt taste to it from running it too dry right out of the box (maybe hitting it a little aggressively, too). I've cleaned both with isopropyl in the last 5 days and both basically came right back to life like a new atomizer. There's no burned taste and the draw is super easy.
You could try taping the painted parts with electrical tape, kate. Just run all the way around the thing taping really tight, then place some paper towel in a shot glass. Now stick the atomizer in so all the taped part is covered (the paper towel is thick so you can really wedge it in there), and use a syringe to inject some isopropyl into the battery end hole of the atomizer. It should run through the atomizer and get absorbed by the paper towel, never touching the paint.
Anyways it, works so far. I'll keep updating to this thread. I only remembered to post because my atomizer started going sideways today, so i took one out of the shotglass that i'd been cleaning it in, popped the old one in with some isopropyl, and the one i've just cleaned smokes like new... again.
Now i am concentrating on getting a better battery. Gonna have to build one of them magnum things.
Damn, awesome vapor out of this thing.
