I got to thinking last night (yeah, dangerous stuff), about whether household vinegar will leach/etch/remove chrome plating.
So, being a little shy on that book larnin', I started an experiment. I took a piece of chrome that was flaking off of the bumper of my pickup truck, and put it into a glass jar with some household vinegar. I also threw in a couple of those plated rivets - to make sure it was all working.
Well, this morning the rivets have had their coating etched off. They are now dark bare metal. But I see no change in the chrome pieces. Not even any "bubbles" on them like show up on the rivets when it starts working on them.
So, vinegar either doesn't work on removing chrome, or it takes a very long time.
Sidenote: If you have some iron that you want to remove the rust from, vinegar will clean it very well. For years museums and archological experts have been using that low voltage electric current and chemical/salt bath to remove rust. But this works just as well - and without play around with electricity near water! And it will eat that rust off the surface, and even eat it out of the bottom of the rust pits! It leaves that dull gray metal look/finish when it's done. And cleanup is just simple soap and water.
Ooooh ... my head hurts from all that thinking last night. Must be time to go fire up the forge and beat up some iron.
