Help! my windows are a wreck!

hey guys, i tried a bunch more stuff as well as talking to a glass guy...he said more than likely my glass is toast because i used varsol to clean it last year and there is heavy oils in varsol that will etch the glass....funny thing though is that i cleaned it off with glass cleaner after varsol and did the same with my front window last year and its not the same problem, its fine....i think im gonna try the steel wool....its my best bet now
