To vineger soak, or not ?

Kevin, I run a 3 inch brass cup brush on a Bosch grinder rated at 11,000 rpm under no load.

Whenever we are speaking about hydrogen and metal, speeding up such a reaction, don't forget about embrittlement. Another reason not to forget about your striking tools for ages in acid. Unless, of course, you know and can bake them safely afterwards. Maybe I'm exagerating, but I don't want any piece of steel flying around while doing my stuff.

I did that with an old sad iron.
Ruined it.
Also a could cast skillets.
Perfectly good metal got heavy pitting.
I scraped it with a screwdriver and the iron was soft.
After I rinsed it well and it dried, it seemed to harden back up.
Maybe my imagination , but that is my experience with leaving stuff in vinegar too long.

This reminds me of the folklore emergency recipe for Common Loon (the iconic, but fish-eating, bird). Place Loon along with large stone into a pot of boiling water. When the stone becomes soft dispose of the bird and eat the stone.
