That oxidation is because the anodizing had become pitted. You can try polishing with Simichrome or similar, but in my experience you actually need to strip off the anodizing, sand out the pits and oxidation and then either buff and polish or get them re-anodized. IMHO these cranks aren't worth that effort as they are relatively available in excellent condition.
