Laundry detergent says "No!"
Never use laundry detergent to wash your underwear! The petrochemical components in laundry detergent, such as fluorescent whitening agents and surfactants, are not good for underwear. Choose a mild soap, medicated soap, or a special underwear detergent. Those professional underwear soaps in supermarkets are affordable and effective, so ladies, please pay attention!
Drying requires care!
Drying underwear isn't just about hanging it up haphazardly. Hang it upside down to air dry in the shade, avoiding direct sunlight to prevent yellowing. Also, don't hang it in a humid bathroom, as this can easily lead to mold.
Change your underwear frequently!
Many people think they should only replace their underwear when it's deformed, but this isn't scientifically sound. Underwear accumulates sweat and bacteria during wear and washing, and even frequent washing may not completely clean it. Therefore, it's recommended to replace your underwear every 3 to 4 months. This will not only keep your underwear clean but also reduce bacterial growth!
