    Default How to remove chrome from aluminum

    Well I'm trying to get some rockers to just straight aluminum. I know mureatic acid and hydrocloric are no no's, I have heard that ultrasonic cleaning (vibration in a water or solution bath) is the best way. Are there any other ways? thanks in advance

    Take them to a chrome shop to have them "stripped". I've tried acid, sandblasting and electrolysis and having them done by a pro yields the best results.

    Certain acids will eat the aluminum (pit) fairly quickly. Plus oxidize the aluminum and you will spend days buffing.

    If you want to see what muratic acid will do to aluminum-take an empty soda bottle and fill it 1/2 way then take a scrap of aluminum and put it in the bottle.Put the cap on tight and then drop the bottle and run like hell! BOOM!!!!!!!Thats what it does!

    I'm interested in doing this also. The PO of my bike went nuts and chromed the rockers and all the cases. I want it gone so I can either do a nice patina on the aluminum or just PC them all black. Some of mine is chipping away though so I'm thinking it might be possible to sand blast it if its brittle?

    On steel you're good. On aluminum you're asking for troubles with this method. I promise.

    Works on removing chrome too. Takes a bit of time but you'll see the chrome come off then the brass or copper layer

    We use muriatic acid to take galled up aluminum on cutters in the machine shop it eats the aluminum in about 15 minutes. I don't want to pit the aluminum.

    Besides overpaying a chromer to take it off, there is no shortcut. Elbow grease and sandpaper is what I use. The chrome comes off easy, it's the nickel that takes forever to get down.

    There's totally a shortcut.. Guess I'm the only one? If you want to remove chrome down to bare metal then use this:

    http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

    Tears down through clear coat paint chrome anything. Doesn't scratch the metal. Although is will swirl aluminum so if you're going to polish it afterwards you're gonna need the brown compound to get rid of the swirls.

    Ive used a scotchbrite disc on a die grinder for a outer primary but it took a while. Polished up nice though. Try a scotchbrite wheel on a buffer maybe? Same concept as the nylon brush but I would think less time in the final buff.

    So I did some thinking about this because it come's up fairly often in my builds. A lot of times, I just find a chromosexual and trade parts. It's practically free and if you're good at it, they'll even give you some money for the "upgrade".
