Neck stain question

[Faux59]

I got a second hand HH jacket and had the bright idea of wiping the collar to remove the previous owner's mojo. All I used was a lightly damp microfiber cloth with water. I did this 3 days ago and the area I made contact with seems to have permanently darkened. It's unsightly and I'm reluctant to try any product if just water had this result. What would you suggest I do before I make it worse? Do nothing and living with it is a perfectly fine answer. Many thanks!

Wipe the entire thing with water for the color to even out, otherwise just live with it.

Could be an interaction with the sweat (salt) and grease of the previous owner. Propably aniline dyed?

Conditioning the whole jacket should even it out a bit.
If it is aniline dyed you can used some diluted vinegar and clean the gooch areas with it, you can get it reasonably wet without damage. (condition afterwards)
Or a mild leather cleaner, but this only works for surface stuff, which this propably is not.

We still talking about cleaning jackets?
