So i just got my first rebuildable atomizer a few days ago. It's a KFL+. I bought Maxim organic cotton balls like I saw people raving about. I do think they work great but for the first like half hour after I wick or rewick my coil I get a kind of gross taste. Eventually it always seems to go away but for that first half hour its kind of gross. Is this normal? Is this why some people boil there cotton before using it? I just want to make sure something isn't wrong.
