So I dismantled an atty to try and understand what REALLY needs to be done to clean these things. Im really not too convinced that dry burns or soaks actually fully clean the atty. When I took it apart after cleaning a couple times and not much result, i found the "Wick" really wasn't very dirty. The coil however was definitely caked with tar or carbon. My plan is to try a couple cleaners on it directly and see what happens. I have a feeling the best cleaner is going to be some kind of spray contact cleaner, not sure if that's something that would be bad to vape after using... (it does evaporate)
