hi i just want to help people with scratches (damn i hate those things lol)
i know quite a few things to cllean them but i dont know if they work they didn't work with me (you never know you might be lucky)
you can use Brasso
vaseline
toothpaste (yes toothpaste)
car polish/wax
you must make sure to go from the inside out and also use a soft cloth never use shoe polish it's a nightmare to get off
