Aaron Marino of alpha m. discusses when and how to clean a leather jacket as well as how to remove wrinkles.
Aaron, once a year, takes his leather jackets at the dry cleaner. The jacket is returned clean and unwrinkled. Wrinkles usually only happen with really thin leather. In this case, hang the jacket but don’t iron. Steam is another option. Don’t try cleaning or pressing on your own- take your leather jacket to the cleaner.
