Is there any way to remove these spots without having them professionally refinished? I have tried griot's heavy duty w/fine grade steel wool, clay followed by never dull, and aluminum foil w/water. No difference at all. Thanks in advance.
0000 steel wool and M105. That combo has made a huge difference on nasty chrome. Test an inconspicuous area first, but that should do it for you. 0000 and Colli Metal wax is also very good, but the 105 will be stronger
