Underwear will easily turn yellow after being worn for a long time. Generally speaking, yellow underwear is mostly caused by urine stains. But everyone knows that urine stains are difficult to clean after a long time. Although underwear is worn inside, it is very uncomfortable if the yellow stains cannot be washed off, and it is also very unhygienic. Cleaning urine stains on underwear is a problem that many people are concerned about. So how to clean urine stains on underwear?

How to remove urine stains from underwear?

1. When the clothes are dry, wash by hand or apply deep cleansing detergent to the stains to completely cover the stains. Leave it for 5 minutes (you can gently rub it), then add detergent and wash normally.

2. White cotton, linen and polyester clothes: Add one bottle cap (40 grams) of stronger laundry detergent into half a basin of water (about 2 liters), stir well, soak the white clothes in it for 30 minutes, and rinse thoroughly. If the stains are still not removed after soaking for 2 hours, take out the clothes, add 1 bottle cap of this product to the basin, stir well, put the clothes in and continue soaking. The cumulative soaking time shall not exceed 6 hours.

3. Clothes made of other materials or colors: Put the clothes in a basin with the stained area against the bottom of the basin. Use the bottle cap to measure 1/4 bottle cap (10 grams) of colored clothing stain cleaner and 1/4 bottle cap (10 grams) of collar cleaner, pour them on the stain, cover the stain with other unstained parts of the clothes to prevent it from drying out, let it stand for 2 hours, and rinse it clean. If the stain remains after 2 hours, add appropriate amount of water to wet the entire garment and leave it overnight.

4. Wet your underwear, then put the toothpaste we usually use (I use the cheap toothpaste), rub it gently with your hands and leave it for a while, then wash it with transparent soap. Finally, rinse it several times with clean water. Let's all try it together. I found the effect is pretty good.

5. Human sweat and secretions contain water-soluble and salt-soluble proteins. The yellow stuff is actually denatured salt-soluble protein. If you want to wash it clean, just add an appropriate amount of table salt or rinse with saline.

Notes on cleaning underwear:

1. Underwear should be changed and washed every day, and washed in a timely manner. Don't leave your underwear overnight, as this will breed bacteria and make cleaning more difficult. On the other hand, many insects like women's underwear, which is very troublesome;

2. Underwear must be hand washed. Underwear is generally relatively small. To increase the friction density, it is recommended to pinch it with the thumb and index finger and rub it closely, so that it can be washed cleanly and thoroughly.

3. The washing liquid must be soapy water, the utensils should preferably be dedicated, and the water should preferably be cold;

4. Avoid exposing washed underwear to direct sunlight. It should be dried in a cool place first, and then placed in the sun for disinfection. Otherwise, the underwear will easily become hard and deformed.
