    I tried using walnut shells on some carbs after soaking them in carb cleaner. the walnut shells just didn't seem to have enough abrasive qualities to remove any stains etc. Turned the air pressure way up--didn't help. Went back to glass beads and low air pressure, did the trick.

    I tried walnut shells on steel rims and they didnt' do much good. Went back to glass beads as well.

    There's an acid used to clean aluminum truck bodies ( the unpainted trailers) that works great for brightening up aluminum manifolds, etc. I have used it several times and it works great. Get the part clean and oil free first with Purple Stuff or similar and water and scrubbing. Then scrub on the acid, work it in good and hose it off thoroughly.
    Don't know just what acid it is, but I bet you could go to a place that washes trucks and find it. I get it from a friend who buys it somewhere in 55 gal. barrels.

    Waaaay back when I was in the Air Force,we used Pecan shells to clean up aluminum panels. Also,some type of acid solution that we called "Skin Brite"

    The acid I think you are talking about is called Alumabrite. Works great.
