You can use a damp cloth to clean leather dance shoes. Once completely dry, a small amount of wax or cream polish will
preserve the leather. Never use regular polish, if you have patent
leather shoes. Instead, apply patent dressing when dry (after cleaning
with a damp cloth). Avoid using harsh chemicals that might damage the materials, and never put your shoes in the washing machine.
