You should clean your leather good on a regular basis to remove the dirt and film that can accumulate from ordinary use. Over time, the dirt will eat away at the leather, compromising the durability and making it more susceptible to wear. Plus, who wants to carry around a dirty leather bag?
Through either wear or after cleaning, the outer protective layer of your leather good will need to be replenished. There are a number of products available to help restore it and keep it, which is done before using the leather good or after cleaning after the protective layer has been removed.
Conditioning your leather good on a periodic basis (the frequency depends on how often you use it) helps keep the leather supple and prevents it from drying out. This can include polishing, which helps restore dye that can wear away with use.
