    Any tips? I have an old chrome Edelbrock signature air cleaner lid that I want to use...but I want to paint it black. Haven't been a fan of chrome in an engine bay for a long time. I prefer the look of polished aluminum or stainless steel...or simply painted.

    I've read I could soak it in muratic acid, bleach or even acetone (not mixed of course) and it would make the plating easily removed. Anybody used these methods with success?

    Haven’t used chemicals, but have had good luck with the little blasting cabinet just roughing it up good so the paint sticks well

    Getting the chrome off is only half the battle and can be done (slowly) with muriatic acid. Then your are left with a nickel plated part that acid won’t touch. I left a nickle plated bolt in acid for 4 weeks and it came out the same as it went in. You can try blasting it, but I never had much luck. Electrolytic stripping is best. Take it to a chrome shop and tell them to strip it and they just reverse the anode-cathode.

    That’s probably the simplest method and quite effective if the goal is to paint or powder coat the part.

    I think Brownells sell the correct acids to remove the chrome, I was looking for stuff to dechrome a luger upper I have on a blue lower. Kind of a cool duo tone P08 pistol, it shoots fine, that's the only reason I'm leery about removing the chrome. jim

    Its been years (over 30) but occasionally we had to remove chrome plating in my Dad's business. I'm almost positive we used hydrochloric acid and water, a 30/40% mixture, so, for example, 1/3 cup HCl and 1 cup water. Place the piece in a container, leave it in until the plating is removed, pull it out, rinse and dry completely.
