The first step is to protect the shoes so that they won't easily get dirty. And if the protection is done correctly, silk can be cleaned. Oil based protective sprays like this for materials including cotton and leather usually also work with silk. To apply, spray the protection on the surface of the shoes to create a layer that will repel water and grime. Whichever brand you choose, make sure it is designed to protect material. To clean after the protection is in place, dab a small amount of clear detergent on a damp white towel and gently tap on the dirty area. Still, take care. Suzhou Cobblers products aren’t waterproof.
