That's what I was getting at when I asked him if the flavor was muted before he cleaned it. He said no.
Its possible that he got the tongue right before cleaning. If it were the case then he shouldnt go crazy trying to fix it. I had the exact same experience and ended up tweaking my Novas so much i broke 2 heads before realizing it was my tongue that was going bad.
....its not for silica its for SSmesh wicks that are not easily removed and a true dry burn will burn off all the residue from ss mesh and you will have to re season the top of your wick afterward...i did one today
