I understood that Cinnamon could be hard on plastic tanks such as clearomizers and now it seems that Ripe Banana might be an issue. All my equipment is plastic or maybe some are acrylic? Not sure really. None are metal or glass So how much of this has to do with how much you add of that flavor? My WL order is on it's way so don't want to be afraid to play with it a bit. No cinnamon but I did get Ripe Banana. Are there others I should watch out for? Can't afford all new tanks and stuff right now. It would be easier to just not use those flavors. Darn it's hard to be a newbie!
