    Cleaning front wheel hubs ???

    Hello

    Does anybody have a good method to clean the aluminum front wheel hubs on a 911? I have put more time than I will admit into cleaning the ones in the picture below and they are still not what I am looking for, and my hands are starting are getting numb from all the chemicals...

    I started out by cleaning with mineral spirits in solvent tank, then soaked them in gas for two days, then another day in carb cleaner. Then back into the solvent tank and I started to scrub down with wire brush, then into the Ultrasonic parts cleaner. I think it might by cheaper to buy new ones. I don't want to bead blast and alter surface finish in a major way. Does anybody have any experience with Vapor Blasting? I have used dry-ice blasting to clean undercarriages with varying results, dry-ice blasting would probably work but it would take a fair amount of ice to get all the nooks and crannies clean.

    I heard about using oven cleaner.

    Bead blast is the best/easiest way. With aluminum you can not typically get the staining off with cleaners. Then treat with oil (name escapes me right now) that is very popular with gun owners.

    They end up looking like these.

    I've been soda blasting them, but it is time consuming - about an hour per hub :/

    The early hubs clean up much better than the later ones, FWIW.

    However you want to blast them, ceramic tumble them afterwards, it closes the cells that were opened during blasting. Makes them look perfect. G.Led

    Dow makes some Aluminum cleaners, which I have used on MB valve covers before. Spray on, let sit, wash off.
    Usually for sale at paint suppliers.
    You will have to protect steel surfaces.
