aluminum stains

[locutus]

i just bought a used honda goldwing. the bike is in pretty good shape except the aluminum engine has some salt stains ( sort of white circular spots ) on it. i tried the search function and didn`t come up with anything usefull. any suggestions on how to remove this? any help would be greatly appreciated!

Did you try metal polish?



I have a tube of MAAS that I`ve used on lots of bare metal with great success. There is a brand, Wenol, I think that is more customary for automotive uses.

Uncoated (to test apply a mild polish, if the applicator turns black there is no clear coat or paint finish) magnesium or aluminium can be polished with a water-soluble polish (Happich Semichrome Polish or Autosol) For difficult to reach places use a felt polishing cone on an electric drill (Dremal or Groit`s Felt Polishing Cone Set) and add a polymer for protection (Zoopseal or Klasse All-In-One)
