There are two reasons why shoes turn yellow: one is that they are oxidized by exposure to the sun after washing, and the other is that they are prone to yellow spots after tidal or sweating.

Methods of whitewashing:

1. The reason for yellowing is that the laundry detergent (or soap) hangs in the shoes and is not completely rinsed out. In addition, white canvas shoes should not be dried in the sun, but should be dried in the shade and in a well-ventilated place.

2. Brush shoes will generally turn yellow because of the deposition of stable substances, such as some stains, sweat, etc., first of all, try to use neutral detergent when brushing shoes (toothpaste is a good choice), you can take white paper (preferably white toilet paper) to wrap the shoes when you wash them, and when the shoes are dry, you will find that the shoes have no yellow marks, and there are a lot of yellow marks on the toilet paper, if the shoes have turned yellow, you can buy lead powder in the store to brush, wash the shoes, brush them when the shoes are wet, and then wrap them in paper to dry, Make sure your shoes are as white as new.

3. Don't brush it with laundry detergent, it's best to use detergent for washing dishes and then rinse it with water, then wrap it in toilet paper, put it in a ventilated place, not in a place where the sun is enough.

4. Wash the shoes with soap or laundry detergent, soak the washed shoes in beer for three minutes, then take the shoes to the balcony, put them in a cool place, and cover them with toilet paper on the upper of the shoes to dry, the effect is obvious.
