You can't use blisters at the peak, but you can wash them with water. The method is as follows
1. First, remove the shoelaces from the state shoes and brush off dirt, dust, etc. Brush on the vamp, sole and bevel edge with a brush, so as to thoroughly clean the shoes.
2. Secondly, prepare a small amount of warm water, add a little toothpaste, and then add some neutral cleaners, in which the ratio of water is three and the others is one, and mix them evenly for later use.
3. Dip the mixture with a smaller brush, gently wipe the upper, and brush off all the stubborn stains on the shoe surface, but be careful not to dip too much water every time.
5. Finally, brush the soles clean, let the shoelaces soak in water, and then wash them with laundry detergent. After washing them all, put them in a ventilated place at home to dry the shoes.
