Coke and it also cleans battery contacts on a car or trk.
I think coca cola cleans pennies the best
Vinegar.

no. The thing that cleans pennies the best is chicken broth! imagine that!
what materital clean pennies better
lemon juice, because it has antioxidense!>*^#$
Vinegar, I'm not really sure, though.
Coke. Vinegar works to but i wouldn't drink it
im not sure if it cleans it best BUT probably acetone(nail polish remover) and i heard coke if you put it over night
neither just melt the pennies then make a new one :)
Vinegar cleans copper well, but I don't recommend cleaning rare or collectable coins as it will ruin the value.
well add juice to the penny
