I like to clean my shoes on a regular, and even more prior to storing them away. Â If they're sneakers, I make sure the soles are clean, as that's the place most likely to be dirty. A warm damp cloth should do. A toothbrush with soap for the smaller areas. Let them dry well. If they're my nicer shoes, I brush and shine them. The regular Kiwi product works well. Stick a shoe tree in them and put them in the original box or the cloth bag (if they came with one). That's about it. Key is to store them clean so they don't have anything permanent in them.
