How did the white clothes turn yellow after being washed dry?

The reason why white clothes turn yellow after drying may be that the clothes are not cleaned after washing, and sweat stains remain on the clothes. Sometimes I see that the collar or cuffs of white clothes are yellow. That's because the sweat and grease left by the body are still on the clothes. Clothes will turn yellow easily if they are not thoroughly cleaned.

You can wash clothes again to make them white. The materials you need: toothpaste, salt, white vinegar and water.

The specific method comprises the following steps:

1. Squeeze a piece of toothpaste into clean water. It should be noted that toothpaste needs to be white.

2. After squeezing into a white toothpaste, add a proper amount of edible salt to the water.

3. Pour the right amount of white vinegar into the basin. White vinegar can be edible white vinegar at home.

4. Gently stir by hand, and evenly stir the toothpaste, salt and white vinegar to make them fully soluble in water.

5. completely immerse the yellow clothes in water for about 20 minutes.

After 6.20 minutes, wash clothes repeatedly with both hands and wash them normally.

7. After a period of washing, yellow clothes will become as bright as new.
