Always handle the leather bag with clean hands since leather is susceptible to oil and grease. The surface of the leather bag can be wiped using a damp white cotton cloth. You can also use leather cleaner for cleaning purposes.
Ensure that you remove stains as soon as you notice them on the bag. Chalkdust can be used for removing stains. Be sure to let it stay overnight for absorbing the stain.
Leather conditioner can be used to moisturize the bag. You should not use alcohol, water, or mineral spirits on your leather bag. Also, you should store away your unused leather bag in bubble wrap.
