Hey guys, I'm getting some sort of white growth looking stuff on my wheels. I bought my suburban used and it had lots of this already, but now the wheels on my 996 are starting to get a few spots! Anyone know what this is and how to get rid of it? None of the usual cleaners like Sonax or Optimum APC do anything.

Aluminium alloys are an alloy in which aluminium is the predominant metal. The highly reactive nature of aluminium metal is normally masked by the protective oxide film, passivation (White rust) which readily forms in moist air and renders the metal kinetically stable. Galvanic corrosion can occur when an aluminium alloy is placed in electrical contact with other metals with a more negative corrosion potential than aluminium

Uncoated (to test apply a mild polish, if the applicator turns black there is no clear coat finish) aluminium can be polished with a water-soluble polish (Happich Semichrome Polish or Autosol)

As usual, you know everything. Thanks! I have P21S metal polish in my kit, will that work?

I don't know everything, just more than most but not as much as some

Use with a white polishing pad , it should remove it
