There are many reasons why clothes are turning yellow. With the increase of washing times, the fluorescent whitening agent in general clothes will be lost, and the clothes will turn yellow and old. It is recommended to use our bright white brightening laundry detergent to clean clothes and trousers. Unique color conditioning technology can make white clothes whiter and colorful clothes brighter. If it turns yellow after washing due to the sun, it cannot be recovered; If general washing product residues or stains are oxidized and turned yellow in the air without cleaning, they can be removed by the following methods:

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