Cleaning game carts with white vinegar?

[pollyisagoodbird]

So recently I purchased an Atari XE game and cleaned it the best I could with 100% rubbing alcohol and a white artist's eraser. I could not get the game to boot, so after looking around, I noticed some folks saying they soak the game contacts in vinegar to help remove corrosion. I'm currently soaking my cart's contacts in vinegar as I type this up, and will wait about 15 minutes overall before I remove it and dry it.

 

So, when using vinegar, should I use regular distilled vinegar, or get industrial strength, non-diluted vinegar? The regular stuff from the store contains water, so I assume that would negate the helpful effects of the vinegar? I' not what you call a chemist, so I wouldn't have the faintest idea if this even will work in the long run lol
