[ARC5] Aluminum Chassis cleaning (and 'that' philosophical question

[Brian]

Hello Wayne,
You can still get alodine chromate in the US? It is not available in Australia allegedly because of its hypothesised carcinogenic properties.

A phosphoric acid etch, or similar product such as "Aluminum Jelly" can be used to clean oxidized AL.  But be aware that it is an acid and may have undesirable effects on other components.  After the acid etch you can use an Alodine chromate conversion coating dip to reduce further corrosion.   

Another possibility that is rather more benign is Evapa-Rust, which will clean AL as well as steel.  However it will also remove paint in the process.
