Aluminium
The message . com
from "Aidan" contains these words:
I think caustic soda would just dissolve the aluminium.
It does if you leave it in too long, but I've done it - oddly, from a
suggestion in a very old electronics mag, and a pint of warm water with
a tablespoon full of caustic soda in it does produce a passable finish.
Anodising it is not - nor is it a patch on proper anodising, but it's OK
for some uses.

Pay no attention to that man behind the curtain.
