The VPI Classic platter is made from raw aluminum without a clear coat, therefore, you can use a gentle metal polish to remove finger prints and tarnish. I use Wenol metal polish with excellent results.
I use Wenol (pronounced veenol) on aluminum, brass, copper, steel, cast iron. The results provide a high-polished finish with little effort. Even with handling, oxidation is slower to return than with other polishes that I have used.
