Any glycerine soap is good for the leather a really like Murphy brand is says it's for wood buy it's wonderful on any leather.
Vaseline is good for moisture, use some kind of baby soap to clean before moisturizing the leather
Olive oil makes it very clean and shiny after
Use soap and a wet sponge or baby oil
Neatsfoot oil actually breaks down the leather so stay away from that. I swear by effol spray w mold inhibitors. Doesn't smell pretty but cleans and conditions nicely
