I am new to the board and to Corvettes. What do y'all use to remove the oxidation from the altenator, compressor and other grey cast metal housings. Thanks so much, Otto

Thanks for your response Dennis.
Well, I tried a small piece of 3M scotch guard-like pad. It did an OK job for a before/after comparison, but it did not look completely clean. I know it was clean, because I tried several mild engine cleaners and such. The rest of the engine compartment looks clean and shiney, except these pot metal (probably cast iron) castings. They look dull.
I can't be the only one with this situation, so more help please.
Thanks, Otto
B17Crew said:I wanted to mention that you can use Mothers Mag & Aluminum Polish on surfaces like your alternator and AC compressor. It also does a nice job on aluminum suspension pieces and any aluminum tubing.
Use a cotton rag and rub into the surface, then, wipe with a clean cotton towel. You will see the shine start to come back! I’ve used a toothbrush before to help scrub in tight spots, you have to watch that the product doesn’t “fling” off the brush though.
Well deserved too!Thank you for the kind words everybody!
B17Crew said:I’ve discovered that detailing the engine bay can be a relaxing experience. Sometimes after a hectic day, it pays to visit the garage and just tidy up the engine bay a little bit more.
Wait, now that I look at that photo, looks like I’ve been having quite a few hectic days. :L

....... not only a detailed engine bay, but a detailed undercarriage, suspension and wheels, interior, engine bay, and complete chassis detailing. :L
