Anodized finish protects against many elements but it’s nemesis are acid and alkalines.

I recall taking my 90 Honda Accord thru the automatic car wash, after repeated washed over the years, the tire brushes intended to scrub the tires had wore away the anodized finish in the wheels. A visible band was left on each wheel about 3-4” above the tire bead all the way around and on all 4 wheels. Never noticed at the time, car wash always applied Armorall or similar after each wash. It wasn’t until I stopped going there did I realize the risks of automatic washing.

Using Armorall always made this “defect” shine to match and blend with the rest of the original wheel sheen. Hides the dull damaged sections well - until it wears away.
