I've amassed a pile of removed aluminium alloy rims, hubs, cranks, stems, brake callipers, derailleurs etc. recently that came from abandoned bikes left in a coastal atmosphere (salt-laden air). Whilst the parts themselves seem sound, the surface oxidation is very unsightly.
Before I consign these to the rubbish skip, is there a way to salvage them? I was wondering if something like household ammonia would be effective in dissolving the white "aluminium rust" from the surface wiyhout detroying the parts themselves? Any ideas?
If there is such a substance, how should I apply it (paint it on, submerse the parts in it?) How long would I leave it on and what would I need to neutralise it? Any other ways to restore things in this condition or are they likely to be beyond repair? None of the corrosion goes beyond the surface as far as I can see.
Or, brass wire brush, wet & dry paper & polish? ( a shine doesn't matter, I could spray them satin black before re-use). I'd rather recycle than add to land-fill if it's at all possible.
Your wisdom would be received with genuine interest. Thanks.
