DO NOT use oven cleaner, drain cleaner, toilet cleaner, or bleach to clean shoes with. These are highly caustic chemicals that will break down fabrics and adhesives, and seriously diminish the life span of your shoes. Baby wipes work very well for cleaning the soles of shoes. Never dry shoes in the sun. It can cause fading, over drying, and cracking. Apply a weather-proofing spray before wearing leather or suede shoes and every time after cleaning.
