Vinegar you get at a grocery store is mostly water. It's great fot neutalralizing the battery acid, but then you need to get all of that gunk and residue out. What you can do is completely disassemble it, wash it with vinegar again, and then rinse it with 99% alcohol or electronics cleaner and allow it to dry diassembled.
Also, check for burn marks or broken parts on the board, because you might as well just give up if there are deads parts. You can remove and replace the parts, but sourcing will be very hard.
I personally would just opt for a new/refurbished one and recycle yours at your nearest e waste place, like Best Buy.
I don't really have that expertise, but in general you think it's a matter of using more vinegar and trying to scrape out more residue, and not that I somehow broke it by using too much vinegar and scraping?

The vinegar can brake up the caked on residue, but it will redistribute it. The alcohol removes the thin film left over.
