Hi there, the oxidisation you have on the aluminium components may look bad and unsightly, but there is an upside.
As another contributor to this thread stated, it would have happened over time anyway, but it is surprising that it has happened so quickly.
The oxide film, once fully established, will seal the aluminium from the oxygen in our atmosphere, an the oxidisation process will stop.
My guess is that the vehicle was given a hot wash to remove the wax coatings often applied to export vehicles transported by sea.
I work in the aluminium industry, and part of the anodising process we use is a hot water bath to Rapidly advance a natural oxide film on the metal to form a protective surface layer.
I don't believe that you have anything to worry about. Removal of the oxide without treating the bare aluminium afterwards will only result in the oxide reforming.
If you are going to 'clean' the metal, I'd suggest applying a spray film to protect it.
CRC has a wax based product called 'soft seal'. It's very good and won't affect any other components of the car. I have parts at home that I machined years ago, and under the soft seal the metal is still as bright as the day they came out of the mill.
