Yellow stains such as collars and cuffs will appear after long-term storage of white shirts, and there are three ways to remove them: the first method is to drop a proper amount of lemon juice into clear water, and then add laundry detergent/washing powder to scrub it clean; The second is to take clean filtrate after spinach is cooked, rub the yellow clothes in the soup and soak them for 10 minutes, then change a pot of warm water and wash them with laundry detergent. The third method is to add vinegar to warm water for washing, and then put it in the sun to dry.
White-collar workers have the habit of drinking coffee or tea at work, and often encounter tea stains and coffee stains on white shirts. If you encounter it, quickly pat the stain with a wet towel until the stain fades or disappears. If it is left for a long time, it can be cleaned with traditional detergent or removed by tapping with cosmetic lotion.
