I’ve tried this method years ago, the high concentration vinegar is expensive as hell. It works in small batches but takes forever. If there is any tin on your boards at all the process gets screwed up.
You are better off using muriatic acid and peroxide. Much cheaper and works much better.
I’ve done a ton of refining of old computer parts. I’ve tried tons of methods. The most efficient way without using extremely hazardous chemicals is what I said.
I have a bunch of scrap now, I’ll do a batch and post the details.

Yes, but you can get muriatic acid at any Home Depot style store. It’s used by plumbers.
I’ll do the post shortly.
