white diamond, exotic metal polish will get rid of any surface contamination. Mothers billet not regular. mothers Only way to get rid of pits or scratches you can feel with your finger nail is sand with 800 grit than 1000 than machine polish with cotton sisal wheel with brown rouge than cotton wheel with jewelers rouge. need about 3500 rpm on 6" wheel. why they were never coated outside cost savings is besides me.
