In view of the yellowing of shoes after long-term use, we can dilute them with a certain amount of white vinegar and soak them for 1 to two hours. When preparing white vinegar solution, we must pay attention to the concentration of water. The concentration should not be too high, which will lead to the damage of shoes, especially the damage of the pattern on the surface of shoes, which is easy to cause the pattern to fade. Of course, the concentration should not be too low, too low is not good for the dissolution of stains. It is recommended to use white vinegar with a small bottle cap and 200 ml of water.
After soaking, brush a little detergent on the edge of the shoes with a small brush. After a few minutes, you will find that the uppers of the shoes are brand new.
In the future, when you brush your shoes and dry them, you can effectively prevent them from turning yellow by wrapping a layer of toilet paper outside your shoes.
