How to wash yellow spots on white clothes? What causes yellow spots on white clothes?

Yellow spots on white clothes are very unsightly. White clothes will easily turn yellow or get dirty after being worn for a long time. White clothes with yellow spots should be washed in time. Yellow spots on white clothes are generally caused by oxidation of sweat stains.

1. Reserve rice washing water or put orange peels in a pot and boil them with water. Soak the yellowed clothes in it and then scrub the clothes to easily restore the whiteness without any side effects on the skin or damage to the clothes.

2. Add a few drops of white vinegar to clean water, soak the white clothes in it, wash them several times, and then wash them according to the normal laundry program.

3. First apply glycerin on the stain, then sprinkle some boric acid powder, and then soak it in boiling water to remove the stain.

Most of the yellow spots on clothes are caused by the sweat not being washed clean. At this time, you can soak the clothes in boiled lemon water, and then wash them according to the usual steps, which will have a better effect. The characteristic of citric acid itself is that it can remove yellowing and neutralize acid and alkali. If there are no impurities on the clothes, they will be more restored to their original color and whiter. The yellowing of clothes may also be caused by the increase in the number of washings. White clothes are most likely to turn yellow. In daily life, you can choose to use a brightening and brightening laundry detergent to wash them, and the effect is also relatively good. After washing, do not expose them to the sun, which is more likely to cause the clothes to turn yellow. You can store them in a cool place or in a place where the sunlight is not so strong. Fabrics that are not alkali-resistant, such as wool and silk, will turn yellow when washed with washing powder, soap, etc., and they cannot be restored. It is recommended to use a neutral detergent for washing. If you want to prevent clothes from turning yellow, you should classify and protect them in daily life. Fabrics should be kept dry during storage. The yellowing of fabrics in wet state is much greater than that in dry state. Before storing clothes, try to clean the clothes, which will also have a better effect. Some things in sweat can turn clothes yellow, so you must pay attention to this.

Dissolve the bright white laundry detergent in water, dilute and stir well, put in the clothes, and wash them completely. If there is still no improvement, add 1 bottle cap of white clothing stain remover (600g specification) to every half basin of water (about 2 liters), stir well, put in the clothes and soak for 30 minutes, and rinse them clean. If necessary, the soaking time can be appropriately extended. If the color stain is not removed after 2 hours, take out the clothes, add white clothing stain remover to the basin (add 1 bottle cap to every half basin of water), stir well, put in the clothes and continue to soak. The cumulative soaking time should not exceed 6 hours. White clothing stain remover is suitable for white cotton, linen, polyester, polyester-cotton, cotton and linen fabrics. Do not use it on colored clothes (including white stripes, white plaids, and white prints), silk, wool, spandex, nylon and other clothes that cannot be bleached with chlorine, and do not use the original solution directly.

Ordinary laundry operations make it difficult to wash yellowed clothes to white, but bleaching is still effective. 84 disinfectant is a good bleaching agent, which can oxidize and destroy the molecular structure of yellow substances, making them fade. Adding 1-2 caps of 84 disinfectant to a basin of water is just enough to bleach clothes. However, chlorine bleach is not suitable for protein-containing fabrics such as wool, silk and leather, and will damage clothes. If there are colored parts on the clothes, 84 disinfectants should be used with caution, because these dye molecules are often oxidized by sodium hypochlorite and turned into other colors.
