Most of the causes of odor are because vinegar is too acidic, so it is best to dilute vinegar with water 1: 3! This kind of foot bath will not only stimulate, but also play a role in sterilization. Use it after soaking, don't flush it again! Just do it!

By the way, I'll give you a general treatment for foot odor:

Add a little tea and salt to boiling water, soak your feet and rub them. No smell. Beriberi; Add one or two pieces of peeled garlic and alum 1 to a catty of aged vinegar, soak it in vinegar for 5 minutes once after 3 days, and wash it once a day for 10 days, so it won't be sent again.
