Four Proper Steps to Wash Your Period Underwear

1: Flush With Water

Give your underwear a thorough rinse right away after taking them off. Furthermore, it’s crucial to only rinse them with cold water; the colder, the better.By bonding the blood to the fabric with hot or even warm water, stains may be difficult to remove.

Additionally, cold water aids in dissolving any clots. And the cleaner your underwear is when it comes out of the washer, the more blood you have rinsed out beforehand. When it comes to rinsing your period underwear, there are a couple of ways you can go about it.

You can first rinse them in the sink in the bathroom. You will want to soak them thoroughly with cool water and continue gently squeezing as you rinse until the water flows clear.

The alternative approach, which many women favor, involves simply rinsing your underwear in the shower. Just keep in mind that cold water is your best friend when it comes to washing your period underwear. Simply keep them submerged in the water and squeeze them until all the blood is gone. If at all possible, washing your underwear right away after taking it off is always preferable to letting it sit in a laundry basket for a while.

2: Treat Any Stains

In fact, if your undies are dark-colored, it is unlikely that you will see any stains on the fabric at all. If the blood has dried, you might notice some staining on the outer layer of your white or nude-colored underwear.

As you’re rinsing and treating stains, it’s important that you don’t put too much elbow grease into your scrubbing since this can break down the stain treatment layer, making the undies feel not quite as dry against your skin.

While rinsing is typically all you need to get fresh blood out of the fabric, if after rinsing the water is running clear, and you still happen to see a stain, here are a few stain-fighting ideas you can try:

For light or dark-colored fabrics:

  • Mild detergent
  • Baking soda
  • Salt
  • Crushed aspirin
  • Meat tenderizer; or
  • White vinegar

For white or light-colored fabrics:

  • Lemon juice
  • Sunlight — try laying your underwear out in the bright sun
  • Hydrogen peroxide

3: Wash

It’s so simple to wash your period underwear!

No need to put them in a separate load; just toss them in the washer and use the delicate cycle with cold water to wash them. Always use mild detergent; avoid using bleach and fabric softener because they can cause the fabric to lose its integrity.

Before washing, place them inside a garment bag to prevent other objects from catching on your underwear. Additionally, it will make them simple to identify in the just-washed load.

4: Air Dry

Air drying is always suggested when it comes to sanitizing your period underwear. Period underwear is specially sealed to keep your clothes fresh and blood-free. Using excessive heat, as you would find inside the dryer (or even hot water) means you run the risk of breaking down the tape used at the seams and gusset.

Air drying your period underwear is a good step in the right direction if you want to prolong their life. Simply put them on the clothesline in the summer or near a heating vent during the winter months.

Why Should We Wash Our Period Underwear?

While it’s common knowledge that period underwear needs to be washed, you might be surprised by some of the reasons why. Here are three justifications for why everyone needs clean period underwear in order to be happy and healthy, as well as why clean period underwear is essential for a person’s physical and emotional well-being.

1. Health

Additionally, wearing the same underwear for a prolonged period of time can seriously harm your health. Long-term skin contact with the microbes and bacteria mentioned above can result in dangerous infections, and the most severe of these can even result in life-threatening conditions like kidney failure or bladder cancer. The importance of having clean underwear for one’s health cannot be overstated; it even has the potential to save lives!

2. Hygiene

If you don’t change your period underwear frequently, bacteria and other microbes build up and fester, frequently resulting in an embarrassing odor and an itchy rash on the skin. Fresh underwear is a non-negotiable necessity to maintain cleanliness and hygiene.

3. Comfort
