I have a Nautilus mini, the juice that was in it was banana split. Vaped the juice for about 3 weeks. Cleaned out the tank tonight and the chimney part on the inside is now hazed. Did the banana flavoring in the juice do this? And is the tank still safe to use? I know that certain juices will destroy plastic tanks, but didn't know that they will mess up the stainless steel part of a tank.
