Amazing! I used Turtle Wax "Ice" and got the same results... I wonder how many people are suffering with fogged/scratched up lenses. In a similar type of thing...my dash lights were very dim even with new bulbs and a good cleaning when I took the dash apart, cussed them every night while driving my '70 XR7...turned the knob all the way to the left and it tried to make them brighter, but they never really got what I considered bright enough. A couple of years ago I had bought a new head light switch, and never installed it (because it still worked) although you probably couldn't count the times it had been used over the 40 plus years...so I got around to putting it in a couple of weeks ago, and whatda ya know...nice bright dash lights again. It is the simple things that make you say "WOW"!
Just curious though, what made you try Brasso?
