How to clean / disinfect vintage (used) shoes?
What products can I use (or household disinfectant sprays, etc.) to clean shoes? vintage shoes, the leather and some are so delicate there a shoe disinfectant spray, you can buy? and I do not use anything that could leave the smell of disinfectant for hospital quality in my shoes. And I do not want anyone to answer "Ew gross shoes second hand", because frankly I do not care, they are impressive.
Try some bleach in the machine washing. Air dry or hang on the line in the sun.
