Engine Rotor Cleaning, Confused! Pics inside
Ok ive watched, aaroncakes vids, pineapples videos, and researched on the forums back to 2002. Spent the day cleanin some rotors in the parts washer. I worked on one rotor while the other soaked in the deeper end of the tub. Used a Water based degreaser.
Spent about an hour this morning scrubbing what i could off the rotors, It wasnt doing much good so i left them in the tub to soak for about 2 hours, came back and hit them with the Brass wire brush again and made some good progress. What i found was on the inside and outside face, i had these weird little spots appear. Its not physically damaged, i cant feel any difference, its still smooth.
After seeing this i took them out and ran them under warm water in the sink, and dried them off.
Ive read of people soaking their rotors in simple green, kerosene ect for days before cleaning.
Any ideas as to whats goin on here? Im not sure if i fucked them up here somehow.

The spots are where the cadmium plating has been etched away by the cleaner. It's no problem.
Few people end up preserving the plating when cleaning rotors. Always amusing to see pictures of beautifully clean raw steel rotors proudly posted up, only to realize that the rotors should be gold due to the plating. Functionally there's no difference...just the lack of plating makes them more prone to surface rust if left in the open air.

PS
the rotors would be raw iron, not steel

Your guess is as good as mine but I say it's somewhere in between like a ductile cast iron/cast steel.
