Menstruation is already uncomfortable for the body, and menstrual blood on the underwear can make people more irritable. During menstruation, menstrual blood is inevitable in underwear. Fortunately, if you act quickly, you can completely remove these bloodstains. Even if the blood has clotted, there are still ways to keep your underwear looking clean.

1. Turn on the cold water tap in the sink or tub. Once menstrual blood is found on the underwear, it is best to wash it with cold water immediately. Turn on the faucet and let the cold water pour out to ensure a steady flow of water. The water must be strong enough to wash away the blood; but not so strong that it will spray everywhere.
The colder the water used, the better. Hot water can cause menstrual blood to clot in the fabric.
2. Grab the crotch of the pants and rinse with cold water. Flip the panties upside down with the blood stained side up and rinse the blood directly with cold water. The more blood that is rinsed off, the better. You can also gently wipe away the blood with your finger or cloth while rinsing.
You might be surprised how much blood can be washed off with just a little water!
3. Pour some soapy water and apply it to the fabric. Water won't completely remove blood stains, you can add a little mild soapy water over the stain to enhance the cleaning effect. Wipe the fabric directly until it lathers, making sure the entire blood stain is covered by the lather.
4. Rinse the underwear. After the blood is covered with soap, wash off the suds with more cold water. Continue rinsing until the water running through the panties is no longer cloudy and there is no suds on the fabric. Then check the panties for any remaining blood stains.

If blood remains, wash the panties again with soap and water. If you still can't completely remove the bloodstain, you may need to try other methods.

5. Wrap the panties with a towel and squeeze out the excess water. Turn off the tap and gently squeeze out excess water. Then place the panties on a thick towel and roll them up tightly. Tap and squeeze the towel for 2-3 minutes to squeeze as much moisture out of the panties as possible.
Do not wring out the panties, as the fabric may be torn and deformed.
6. Hang up your panties to dry. If you have a clothesline at home, you can use clothespins to hang your panties on the clothesline to dry. If you don't have a dedicated space for drying clothes in your home, you can also hang them on a shower curtain rod, towel rack, or doorknob to dry. In short, put them in a well-ventilated area and let them dry thoroughly.
For example, if you hang your panties to dry in the bathroom, remember to leave the door open to allow air to circulate.
To dry your panties quickly, hang them in front of a fan.
Do not put panties in the dryer unless the blood is completely gone. Heat can cause blood to clot in the fabric, making it harder to clean up afterwards. The heat of the dryer can also destroy the elasticity of the fabric, so it is best to choose to air dry.
