[quote name='Sang' post='590338' date='Oct 7 2008, 03:07 AM']What's Brasso? is that the brand or the product name?[/quote]
Yes mate, Brasso is a brand of metal cleaner that can be brought at most shops like Asda, tesco etc, But its only a mild cleaner/polish that will remove dirt from the laquer on the light lenses, I used to build headlamps and we used it all the time to remove scratches and marks from the lenses and does work quite well,
T-cut does the same thing as again its only a light abrasive and should remove the discolouring from the headlamps and can be brought from most car shops
