How to clean yellowed underwear

The private parts of the human body are the most important and fragile parts, and need to be carefully cared for. Therefore, when washing underwear that fits closely to the skin, special cleaning products are generally used, and the underwear should be washed separately from other ordinary clothes. Some people find that their underwear turns yellow when washing, and ordinary washing methods cannot wash it clean. So, how do you clean yellowed underwear?

1. How to clean yellowed underwear

1. When the clothes are dry, wash by hand or apply deep cleaning laundry detergent to the stain, completely covering the stain. Let it stand for 5 minutes (you can rub it gently), then add laundry 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 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 part 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.

2. Precautions for washing 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 tightly with the thumb and index finger, and rub it finely, so that it can be washed cleanly and thoroughly.

3. It is best to change your underwear every six months. Generally speaking, underwear that is used frequently should be changed every six months. If your underwear becomes deformed, the material becomes dry and hard, or the stains cannot be washed off, you must replace it promptly.
