How to wash white clothes that turn yellow?

In life, we often encounter such a thing, that is, white clothes easily turn yellow. This kind of thing makes many people feel distressed. Everyone likes to wear white clothes, and usually washes clothes separately, for fear that other clothes will fade and stain the white clothes. When white clothes turn yellow, how do we wash off the yellow?

To wash red ink stains on clothes: wash new stains with cold water first, then soak them in warm soapy water for a while, and then rinse with clean water; old stains can be washed with detergent first, and then rubbed with 10% alcohol solution to remove them.

Ink stains: Mix rice grains and detergent, apply it to the stained area and rub it, then rinse it with clean water; you can also use a solution made of one part alcohol and two parts soap to repeatedly apply it, which also has good results.

Ballpoint pen stains: First, you need to check what material the clothes are made of. The general practice is to place a towel under the stain, use a small bristle brush dipped in alcohol to gently scrub it. After the stain has dissolved and diffused, soak the clothes in cold water, apply soap and gently scrub it. Repeat this two or three times and the ballpoint pen oil can be basically removed. If there are still a small amount of residues after washing, you can remove them by soaking or boiling them in hot soapy water. This method can be used for cotton and cotton-polyester fabrics. If the woolen material is stained with ballpoint pen oil, first soak the stain in a mixed solution of trichloroethylene and alcohol (in a ratio of two to three) for 10 minutes, while constantly brushing it gently with a brush. After most of the oil stains are dissolved, wash it with low-temperature soapy water or neutral laundry detergent.

Mildew stains: Wipe with 2% soap and alcohol solution, then wipe with 3%-5% sodium hypochlorite bleach or hydrogen peroxide, and finally wash.

Sweat stains: When clothes are stained with sweat, yellow spots will easily appear over time. If there are sweat stains, soak the clothes in 5% salt water for 1 hour, then slowly rub them clean.

The wool sweater is contaminated: dissolve the neutral soap liquid in boiling water and add a tablespoon of borax. When the temperature drops to 60 degrees, soak the wool sweater in the soap liquid for three or four hours. Then gently rub it in warm water of 40-50 degrees, and finally rinse it with warm water. If there are still some stains that cannot be washed off, you can use soap solution and two tablespoons of turpentine to make an emulsion for washing. After washing, let the sweater dry naturally. When it is mostly dry, you can use a not too hot iron through a layer of cloth to iron it dry and flatten it, and then hang it in the sun for a while.

There are many other ways to wash white clothes, such as freezing them in the refrigerator. There is a method published in a newspaper: wash the yellowed and old clothes, wrap them in plastic bags, put them in the refrigerator for a while, and they will be better when you take them out. You must keep the clothes you wash well, as many clothes will turn yellow if they are stored for a long time.
