DO NOT USE MINK OIL OR NEATSFOOT OIL! They soften the leather too much and cause it to be too pliable. I would use Lexol cleanser first if its really dirty and then Lexol conditioner if I was going to use it. If its not too dirty just give it a light cleaning with some mild soap and water, let it dry completely, and then a light rub with a little Lexol. Remember, two light treatments is much better than trying to coat it down all at once. If you can't get Lexol, wipe it down with a mild soap wash, let it dry and then rub a little neutral shoe polish on it.
