Take a look at some of these things to treat and maintain a leather bag after being properly cleaned:

     Store the leather bag well. Store the leather bag by using dusty bag or spunbound cloth fabric so that the leather bag is not easy to damp. If stored in closed cabinets use silica gel
     Do not stack one bag with another bag
     Do not use the bag as a protector either during heat or rain
     Use a leather conditioner or moisturizer regularly at least once a week for the treatment of leather bags

Do not forget to choose a moisturizer or conditioner made from natural.
