Why are white-washed shoes wrapped in white paper?
The reasons are as follows: Toilet paper is used for shoes to prevent yellow marks from being left on shoes. The shoes can't be washed thoroughly, and a small amount of dirt is dissolved in the residual water, such as protein. The so-called yellowing is actually the product of oxidation of those dirty things in the air.

Although the shoes seem to be washed with clean water, there are still many residues of washing powder or soap on the vamp. If the shoes are dried directly, there will be some yellow spots after drying, and the shoes look ugly.

However, if you can wrap a layer of paper towels on white and light-colored shoes, when the water on the surface of the shoes evaporates, the dirt dissolved in water will remain on the paper towels instead of on the uppers. After the shoes are dried, tear off the paper towel and the shoes will become clean as new.

Precautions for cleaning small white shoes:

1, and the washing temperature cannot exceed.

Most synthetic materials at 45 degrees will change at high temperature, so the ambient temperature should be less than 45 degrees regardless of wearing or washing, which is why washing shoes should avoid hot water and exposure after washing.

2. Cleaning chemicals.

Otherwise, the shoes will turn yellow, and the edge of white sports shoes will turn yellow easily because of the chemical residue in washing powder and a little rust residue in water. You can stick a tissue or toilet paper on the surface, but this is not the best way.

This pair of shoes is yellow. After washing, coat it with white shoe powder, and then cover it with toilet paper to dry. If you can't buy white shoe powder for a while, you can also use water and alkali on the wall of the kettle instead. That is, we drain and grind water and alkali and put them on the cleaned vamp, so that the shoes can be as white as new.
