Thanks everyone!
I'll try it but if this was the problem why would I be getting the smell from a dry burn? I don't see any damage on any of my carts from melting.
My 510 attys came from TW and I vape alot with them. I use my DIY VG based ejuice with flavors from Cabella this requires more frequent cleaning in my opinion. I clean the attys regularly doing a short 20 min coke bath, rinse with water blow out and rinse and blow again. Then I let them dry a little and dry burn per mobyghost instructions on youtube for 4 to 5 secs....let cool...try another dry burn 4-5 secs...let cool. He said to do it until you see a red glow on the atty inside. There is smoke and nasty smells during the dry burn but I dont worry since it is getting rid of old ejuice etc. Then go through water rinse again to remove what scum flaked off during the dry burn. Some people had dead attys ready to throw away and tried all this with success.
When I go to fire them up after cleaning I always make sure that I prime the atty too. I do get an ugly taste for my first dripping and occasionally get nasty smelling smoke but it goes right away. I never inhale this first round of vaping.
BTW I heard the crest is hard on attys...but have never tried it myself.
