Opinions on V Nickel

[TheCaribbeanDigger]

I folks I found this V Nickel a couple days ago and wanted to clean it up a bit. I soaked the coin for 4 days in white vinegar and gave it a couple of gentle scrubs with a soft tooth brush. This is before and after. U guys think I should finish cleaning it up? What could I use to clean it up a bit more?

I usually soak my coins in olive oil to get the color back, but just now while looking at the thread talking about cleaning with peroxide, it states that there is a coin preservation fluid or you can use Vaseline. I know for fact that my father uses Vaseline on his coins and it works pretty good to give it the natural color back.
