RodKnock,
If you get light scratches you can use the Nuvite S polish and a soft cotton towel and buff it by hand. The microfiber towels tend to leave a pattern that you can see when used with the polish. For light dusting and cleanup you can use the microfiber towels.
For cleaning bug splats,
oil and grime off the polished finish you can use Nu-Image found at the bottom of this page:
