Traveling shoes will get muddy when worn in rainy days, and they won't be brushed off when they are black. How can I brush them clean?

I have heard of a method on the Internet, which works well:

Apply a little toothpaste to the dirty place, wipe it with a soft dry cloth, and then wipe it with a wet cloth. The effect is not obvious, but small stains can still be solved ~ ~! !

My method for many years:

Buy a pack of baking soda (soda ash), which is the kind that makes steamed bread.

After cleaning with detergent, brush less baking soda, and lightly brush the unclean places with water, and they will be as clean as new immediately ~ ~! !

This is absolutely clean, even the dirty things that can't be brushed off in the gaps of old shoes can be brushed clean. The secret of brushing shoes for many years is oh ~ ~! !

Supplement: baking soda can't afford a dog, so be sure to pay attention to the dosage. Don't use too much ~ ~! !
