Default vinegar to clean brass

After tumbling my brass in corn cob media, I deprimed, cleaned the primer pocket and resized. After all that I tumbled my brass again in a 50/50 water and vinegar solution and now I'm hearing vinegar is bad for the brass and can weaken it. Is this true? Someone help this rookie out.

It works for cleaning black powder Ctg. cases. The vinegar cleans but turns the cases a weird orange color. I have never heard of using vinegar on smokeless powder brass.

I do not believe vinegar will weaken the brass significantly. Amonia is VERY bad for brass. Your source is likely confused

Vinegar is mild acetic acid and will attack brass cases. It can be used for cleaning but I found it left the cases with a pink hue which results from the vinegar reacting with the zinc in the cartridge case and leaving the copper untouched.

Long Term exposure will definitely weaken the cartridge case, possibly to a dangerous level.

i dont get that in depth with cleaning brass. long as it isnt corroded i just run it in the tumbler with corn cob for 5 or 6 hours and it comes out pretty damn clean. i scavange a lot of brass and some of it has reallllly bad tarnish but a multi hours ride in the tumbler pretty much gets it clean enough to load and shoot.

I have cleaned many .45-110 Sharps cases with vinegar. I have never noticed any damage to the brass except for coloration. The .45-110 Norma brass is over $4.00 dollars each. So you watch them closely.

Sometimes if you add salt the vinegar will work even better.

That is why you do not soak brass for an hour in pure vinegar. A bit in water is sufficient. Just till clean and rinse thoroughly
