Personally I detest the polishing of parts. most parts, especially Campi, were never mirror shinny leaving the factory but had a bright satiny finish, IMHO polishing destroys the look and the anodizing meant to protect the part.
for cleaning, since I don't have a garage or access to a hose I use copious amounts of Simple Green and an old tooth or bottle brush and water
