Why do white cloth shoes have yellow stains after brushing and drying?

White cloth shoes have turned yellow, and white cloth shoes must be exposed to direct sunlight, especially many elephant wool, silk, nylon and other products, after direct sunlight, they often have a photochemical reaction to make the color yellow. I have a way to wet my shoes and apply the toothpaste evenly on them, and after the toothpaste has cooled and dried for a while, I can scrub it. It is usually better to wash shoes with toothpaste than with soap.

After brushing. Immediately the toilet paper was tightly wrapped.

Wait until it's dry. You find that the toilet paper is all yellow.

But the shoes are still white Fundamentally eliminate the reason for the yellowing of shoes: first of all, try to use neutral detergent (toothpaste is a good choice) when you brush your shoes, and when you wash and dry, you can take white paper (preferably white toilet paper) to wrap your shoes whole, and when the shoes are dry, you will find that the shoes have no yellow marks, but there are many yellow marks on the toilet paper. In addition, if you wait until the shoes are very dirty before brushing, you must use detergent to wash them clean, and you can use less detergent by wiping them with a soft cloth dipped in water.

You can also wash your shoes with soap or laundry detergent and soak them in beer for three minutes.

Then take the sneakers to the balcony, place them in the shade, and cover them with toilet paper on the upper and let them dry!

The effect is obvious!

After each wash, it is pasted with toilet paper and dried, and due to the capillary phenomenon, the yellow stain seeps into the paper.

Oxidized (chemically reacted with oxygen in the air) under the sun's rays of the sun, it turns yellow.

White shoes are the most basic type of shoes, and they are very versatile, they can be worn with different colors and styles, and they are not picky at all. However, many people can't wash the little white shoes as white as the original when they are cleaned, and some of them are obviously very clean when they are washed, and there will be yellow marks after drying, so what can be done to remove the yellow marks?

After washing the white shoes, it was found that the shoes had yellow spots on them. At this time, you can prepare some clean paper towels, pour white vinegar on the paper towels, and then lay these paper towels flat on the white shoes, and then dry them in a cool and ventilated place.

If the white shoes are made of leather fabric, the yellow places we can wash with lemon juice. At this point, we can drop lemon juice on the yellowed part of the white shoe, wait 30 minutes, and then rinse with water.

Because when the shoe is in the air, the moisture on the upper will evaporate to form a capillary action, which will cause unrinsed impurities to run to the surface of the shoe, causing the upper to turn yellow. Therefore, we usually wrap the small white shoes in toilet paper after washing, so that the toilet paper replaces the upper, and the capillary phenomenon occurs on the paper, which will turn the toilet paper blue and yellow, and the white shoes will become white. You can also buy a lead stucco shoe in the store, wet the upper, brush it on, and then wrap it in paper to dry, so that the shoes will be as white as new shoes.
