Any one know which or a better make shift solution?

If properly anodized it should eat into the top layer of material so the only way to fully remove would be to rub down with sand paper/scotchbrite.

Hmm i thought it was just the oxide layer??

I have done it with a set of straitline levers (i reckon they anodize properly) and it took it off. Needed scotchbrite to take away the matt finish though.

i used drain cleaner.

if you end up with blackened alloy then you left it on too long

The anodic film is an oxide that eats into the substrate as well as grows. How bigs the part?

Yep, search doesnt tell me whether its thick or thin bleach.

Its a crank set, chain device and lever blades.

Dont have any caustic, will probably just leave it for now since i dont have any thin bleach if it was that.
