Now I have this leather vest which I LOVE! And it has developed this odd pungent smell to it, I REALLY want the smell of actual leather back in it. What should I use? The leather is not like discoloured or dirty anywhere. It is just that odd smell.

How do I get the smell of leather back into my vest?! T_T
By the way if it helps its a very soft leather ALMOST like lambskin, but it is a soft type of cow hide
