Black stain spreading on keris during vinegar cleaning

I hear that, Alan. I did not intend for my note to be a discouragement to try others, only to share my experience with citric acid.

Not sure if I'm glad I made the mistake, but I'm glad I learned from it.

I have a tendency to be quite conservative and unwilling to try other things after I make a regrettable mistake, so thank you for the reminder to keep trying other stuff I come across.

Apolaki, I've seen black stains like those when I was cleaning my Tuban-style pamor sanak keris - especially what is seen on the cleaner side of the blade. I just put it back in the cleaning solution (vinegar) and took it out to brush with a soft toothbrush more often. Eventually it came good. It's still quite clean.
I wouldn't worry too much, as Alan said just try to clean it again because there is rust on it.

One of these days Jaga, I'm going to try Coca-Cola on a keris --- and a few other things.

There are some particularly nasty concoctions that some people in Jawa use make blades look old. Some of these devil's brews can eat a keris over night.

It is, I believe, meritorious to try different things, but it is even more so to try them slowly, gently and with care.
