I believe many women have discovered that after wearing their underwear for a period of time, they will find yellow residue on them after washing and drying them. So, why do girls’ underwear turn yellow? How can I clean it? How to choose underwear correctly?

Why do girls' underwear turn yellow?

1. Urine

Human urine is acidic and alkaline, carrying the body's excrement and secreted residue, so it is usually yellow. If women do not use paper towels to wipe their private parts after going to the toilet, urine residue will be formed in their underwear, and their underwear will gradually turn yellow.

2. Gynecological inflammation

Women suffering from gynecological inflammation will experience increased leucorrhea, secretions flowing out of the private parts and turning yellow in color. Yellow watery liquid can make underwear yellow. Vaginal inflammation will seriously affect the life and work of female friends. Once discovered, it is necessary to seek medical treatment as soon as possible to avoid delaying the condition.

3. Menstrual blood residue

Most women accidentally get menstrual blood on their crotch during menstruation. Underwear stained with menstrual blood is generally not easy to wash off, and there will always be yellow marks left on the crotch. It is recommended to use special detergent for underwear to soak for 10-20 minutes, then rub it with your hands and wash it. Do not wash with bleach water, because chloride is highly irritating and may cause chemical residue problems.

4. Material issues

Underwear made of nylon has low sweat absorption capacity, is not breathable, and has poor light resistance. It is easy to yellow and age when exposed to the sun for a long time. Cotton products are more suitable for women to choose underwear. It has good hygroscopicity and warmth retention properties, and is soft and comfortable.

How to clean girls' underwear that turns yellow?

1. When the clothes are dry, wash by hand or apply deep-cleaning laundry detergent to the stained area to completely cover the stain. After leaving it for 5 minutes (you can scrub it gently), add laundry detergent for regular washing.

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

3. Other materials or colored clothes: Put the clothes into a basin, stick the stained area to the bottom of the basin, use a bottle cap to measure the strength of the laundry detergent, take 1/4 bottle cap (10 grams) of colored clothes and 1/4 bottle cap ( 10g) clean the collar, pour it on the stained area, cover the stain with other stain-free parts of the clothing to prevent it from air drying, let it sit for 2 hours, and rinse it clean. If there are still stains after 2 hours, add an appropriate amount of water to moisten the entire garment and leave it overnight.

How do girls choose underwear correctly?

1. High-waisted briefs

Suitable for: Girls with no excess fat on the waist and abdomen, no fat on the buttocks and who love sports.

Suitable accessories: When wearing aerobics clothes, the crotch and buttocks will not be exposed. Due to the slim shape, the lace edges will not be exposed, so it is suitable for wearing with summer thin skirts and pants.

Not suitable for people: People who have excess fat in the abdomen; people with sagging buttocks.

2. Mid-waist boxer briefs

Suitable for the crowd: It is a style suitable for all body shapes.

Suitable for matching: It can be worn with almost all trousers and skirts. What you need to avoid is skirts and trousers with mid-waist and low-waist designs, because you may inadvertently reveal the waistline of your underwear when you raise your hand.

Not suitable for the crowd: People who want underwear to support their lower body curves will be disappointed with this model. Because "flattening" the abdomen and "lifting" the buttocks require special cutting and tailoring methods. Although this style leaves no marks or marks after wearing, it does not have any special support.

3. High-waisted trousers and boxer briefs

Suitable for: This style of underwear is most similar to traditional trousers. Girls who want to slim down their tummy and lift their buttocks through its three-dimensional design of the abdomen and buttocks and reduce the sagging feeling in their overly thick thighs can choose this style.

Suitable for matching: When paired with trousers, the buttocks and legs will be naturally traceless. But be careful when wearing skirts, because knee-length skirts and short skirts will move a few centimeters above the knees when people sit down, so sit down and try them on before going out to avoid embarrassing yourself in front of others. Of course, skirts with high slits also have this problem. It is better to take a few steps in front of the mirror so that the underwear does not appear and disappear.

Not suitable for everyone: This versatile design can be worn by almost everyone, except those who don’t want to be too restrictive.
