Some green corrosion won't come off and I don't know how to remove it without a few more vinegar runs.
Varta is the best to teach you trace rebuild 😀
It might have gotten under the solder mask. Hopefully you've neutralized it, otherwise you'll have to dig it out, if it has permeated through the first layer of fiberglass substrate (don't do this right now, just watch it for a while if it's not accessible).
See here for photos where I had to dig out some PCB eating corrosion on my SC-55 synthesizer:
