Bleaching and yellowing of white clothes is a very common problem, but there are many ways to solve this problem. Here are some things you can try:
Wash white clothes with rice washing water. Soathing the white silk fabric with skim milk before washing it, or adding 2 tablespoons of milk to the water for the last rinse, will preserve the natural color of the white silk fabric and prevent it from turning yellow.
Bleach with lemon juice. Add a little lemon juice to the water to make your clothes whiter. Or add fresh lemon juice to the yellowing of white clothes, add some salt and rub gently, and then expose the clothes to the sun to make the yellow fade.
Bleach with disinfectant. Soak with disinfectant or bleach powder with water, pay attention to the ratio of disinfectant and water and soaking time, the disinfectant has strong decontamination power, but it is harmful to clothing. It is recommended that after rinsing, it is best to soak it in clean water for another 15 to 30 minutes to reduce the damage of the disinfectant solution to the clothes [3].
Use the rice washing water method. Yellowed silk clothes can be soaked in clean rice washing water, change the water once a day, and the yellow color can fade after two or three days.
Put orange peel in a pot and boil it with water, soak the yellowed clothes in it, and scrub them to make the clothes white.
The above are some methods that you can try and hope it can help you. If the problem persists, it is recommended to contact a professional laundry for treatment.
