Default Home made brass cleaning solution

This is probably old hat for old-time reloaders. As a test, I put a handful of the worst tarnished and discolored 9mm range brass into a cup of 50/50 vinegar and hydrogen peroxide. Let it stand and walked away from it. When a came back a few hours later to check it out the mixture was bluish and the brass inside and out was like brand spanking new. Both hydrogen peroxide and vinegar are cheap but not as cheap as crushed walnut reptile bedding for use in a tumbler. But man o man, does it work well and fast and makes no noise.

I wonder how many reloaders clean their brass this way, or perhaps, clean some brass to look like new for those special reloads?

And oh, since I had no white (clear) vinegar, I used apple cider vinegar. My brass smells like apples. Just kidding.

Someone in-the-know might want to comment on the integrity of the brass after using the H2O2 and CH3-CHOOH (3% Acetic acid in water which is vinegar). I did a batch of 50 rounds in a plastic cup (recommended non metal) and it took about 20 minutes ti clean them up. If the brass is deprimed first then the primer pockets and primer hole get cleaned out as well.

I was actually going to say that the "bluish color" was from the copper being dissolved slightly. So be careful.

Thanks. Only takes about 5 - 10 minutes to clean them up. I'm surprised I'm not hearing from the experts on this. Seems to me this cleaning solution has been around for quite some time.

I don't know about the etching not an expert, but this is what I use an old NRA recipe, no hydrogen peroxide. Perhaps the salt or the dishwashing liquid neutralizes the vinegar? I don't know but it works nicely.

I do quite a bit of metal etching and patinazation, so I'm familiar with chemical treatment of copper and brass. One thing I want to point out is to rinse the brass very well with hot clean water after this treatment to stop the etching process. You can also increase the ability of these solutions to clean brass by adding a drop or two of dishwashing detergent to lift oil films off the brass...
