Well not sure if I screwed something up but when putting the diffusers back in there was some moisture between 2 of the panels. So I grab a microfiber and went to dry it up but then it looked like it was taking some coating off with just water. I thought maybe it was nicotine, so once I did one spot I had to do the rest because of the way it looked. Really had to do the wax on wax off to get it back presentable. Is there a coating that should just come off with water?
