Surface stains:
      The surface of shoes is easy to absorb dust, and can be lightly brushed along the surface texture with a brush to remove floating dust. Then mix white vinegar and water in a 1:1 ratio to make a cleaning agent. Wet all the shoe uppers, including the upper area, with a clean sponge to avoid color difference after drying. Put the shoes in a cool place to air dry, or use the cold air stop of a hair dryer to dry them.

Internal cleaning:
      Shoes generally do not have oil stains or fruit stains inside, only dust and odors need to be removed. Mix crude salt and baking soda in a 1:1 ratio, pour them into the boots, pinch the shoe opening tightly and shake it up and down for 2 minutes, then let the shoe opening bag stand still for 5-10 minutes. After pouring out the mixture, use the cold air of a hair dryer to blow out the residue and clean it.
