1. After washing, the sun or high temperature burns lead to yellowing, which cannot be recovered. It is recommended that clothes should not be exposed to the sun or close to high temperature;

2. Alkali-resistant fabrics such as wool and silk are washed with washing powder and soap, which leads to yellowing and cannot be recovered. It is recommended to clean with neutral detergent;

3. With the increase of washing times, white clothes tend to turn yellow and get old. It is recommended to use our brightening laundry detergent to clean clothes. Unique color conditioning technology can make white clothes whiter and colorful clothes brighter.

4. Washed product residues or stains (such as sweat stains) are oxidized and turned yellow in the air, or turned yellow due to moisture.

In the first two cases, the clothing fiber is damaged and there is no way to recover it. I suggest taking it to a professional laundry and trying to recover.

The latter two cases belong to the problem of color stains on clothes, which can be treated by the "color stain soaking method" of the blue moon:

Fabrics of different materials and colors have different treatment methods, as follows:

1. Dissolve the blue moon brightening laundry detergent in water, dilute and stir it evenly, put it into clothes and clean it as a whole.

If the clothes turn yellow, it still doesn't improve.

soak

(1) Pure white clothes made of pure cotton, linen and polyester: every half basin of water (about 2 liters), add 1 bottle cap (40g) blue moonlight white clothes stain (600g specification), stir well, soak in the clothes for 30 minutes, and rinse off.

* If necessary, the soaking time can be extended appropriately. If the color stain is not removed after 2 hours, take out the clothes, put the white clothes into the basin (add 1 bottle cap to each half basin), stir evenly, put the clothes into the basin and continue to soak, and the cumulative soaking time shall not exceed 6 hours.

(2) White clothes made of colored materials: pour a small amount of water (about 0.5 liter) into the basin, measure the colored clothes (one for each 1.5g) and the collar (one for each 60g) with blue moonlight colored clothes (600g), and mix them evenly. Soak in clothes overnight, and then rinse.

* The amount of water should make the clothes just wet, and the net content of colored clothes and collars should increase or decrease according to the amount of water. If there are still stains after soaking for one night, the soaking time can be continued to be extended.
