How Do You Wash Period Pants?

When it comes to the question of how to wash period pants, many people may not realize that these innovative undergarments can actually be machine washed for easy and convenient cleaning. Gone are the days of soaking and hand washing. With period pants, you can simply toss them in the washing machine and let it do the work for you.

Period pants are designed with advanced technology that allows them to absorb menstrual flow and prevent leaks. They are made from highly absorbent materials such as bamboo or cotton, which can hold a significant amount of liquid. In fact, period pants can absorb up to two tampons' worth of blood, providing protection and peace of mind throughout the day. After wearing them, simply rinse off any excess blood and place them in a mesh laundry bag, then wash them on a gentle cycle with cold water and mild detergent. It's as simple as that!

Understanding the Basics of Washing Period Pants

Period pants, also known as menstrual underwear or period underwear, have gained popularity as an eco-friendly and sustainable alternative to traditional menstrual products. These absorbent undergarments can be used alone or as a backup to tampons or menstrual cups. While the overall care for period pants is similar to regular underwear, there are a few key considerations when it comes to washing them. In this article, we will delve into the best practices for washing period pants to maintain their effectiveness and longevity.

1. Preparing Period Pants for Washing

Before washing your period pants, it's important to remove any excess blood to prevent staining and odors. Start by rinsing the pants under cold water until the water runs clear. You can do this in a sink or by holding them under a gentle stream of water. Avoid using hot water, as it can set stains and make them more difficult to remove.

If the pants are heavily soiled, you may want to soak them in cold water for 15-30 minutes before rinsing. Adding a small amount of mild soap or a gentle stain remover to the soak can help with stain removal. However, be sure to check the manufacturer's instructions, as some detergents or stain removers may affect the absorbency of the pants.

Once the excess blood has been rinsed out, gently squeeze the pants to remove any remaining water. Avoid wringing or twisting the fabric, as this can cause damage. Instead, press the pants between your hands or against the side of the sink.

1.1. Handling Stains on Period Pants

If you notice stubborn stains on your period pants after rinsing, there are a few methods you can try to remove them:

  • Spot-treatment: Apply a small amount of stain remover or liquid detergent directly to the stain, gently rubbing it in with your fingers or a soft brush. Let it sit for a few minutes before rinsing.
  • Peroxide soak: Mix a solution of hydrogen peroxide and water in a 1:1 ratio. Soak the stained area for 30 minutes, then rinse thoroughly.
  • Baking soda paste: Make a paste using baking soda and water. Apply it to the stain and let it sit for 15-30 minutes before rinsing.

2. Machine Washing Period Pants

Most period pants are safe to machine wash, but it's important to follow the manufacturer's instructions to ensure optimal care. Here's a step-by-step guide to machine washing period pants:

  • Step 1: Place your period pants in a mesh laundry bag to protect them from getting tangled or damaged during the wash cycle.
  • Step 2: Select a gentle or delicate cycle on your washing machine. Avoid using hot water, as it can compromise the integrity of the fabric and elastic.
  • Step 3: Use a mild, fragrance-free detergent. Avoid using fabric softeners or bleach, as these can reduce the absorbency of the pants and cause irritation.
  • Step 4: Start the wash cycle and allow it to complete.
  • Step 5: After the cycle is finished, remove the mesh laundry bag from the machine and gently squeeze out any excess water.
  • Step 6: Hang the period pants to air dry. Avoid using a dryer, as the heat can damage the fabric and elastic.

2.1. Special Considerations for Period Pants with PUL Layer

Some period pants have a waterproof layer called PUL (Polyurethane Laminate) to provide extra leak protection. If your period pants have a PUL layer, there are a few additional considerations for washing:

  • Step 1: Turn the period pants inside out before placing them in the mesh laundry bag.
  • Step 2: Use the gentle or delicate cycle on your washing machine, but avoid using fabric softeners or bleach.
  • Step 3: Hang the period pants to air dry, making sure the PUL layer is facing outwards. Avoid direct sunlight, as it can degrade the PUL.

3. Hand Washing Period Pants

If you prefer to hand wash your period pants or don't have access to a washing machine, follow these steps:

  • Step 1: Fill a clean basin or sink with cold water and add a small amount of mild detergent.
  • Step 2: Place the period pants in the soapy water and agitate them gently for a few minutes. Avoid scrubbing or rubbing too vigorously, as this can damage the fabric.
  • Step 3: Rinse the pants under cold running water until the water runs clear.
  • Step 4: Gently squeeze out any excess water from the pants.
  • Step 5: Hang the period pants to air dry, away from direct sunlight.

3.1. Drying Period Pants

When it comes to drying period pants, it's best to avoid using a tumble dryer. The heat from the dryer can damage the fabric and elastic, reducing the lifespan of the garment. Instead, opt for air drying by hanging the pants in a well-ventilated area. Avoid drying them in direct sunlight, as it can cause fading and degradation of the fabric. Once the pants are completely dry, they're ready to be worn again or stored until the next use.

How Often Should You Wash Period Pants?

The frequency of washing period pants largely depends on individual preferences and the flow of your menstrual cycle. As a general guideline, it's recommended to wash them after each use to maintain hygiene and freshness. However, some people may choose to wear their period pants for longer, especially if their flow is light or they use them as backup to other menstrual products. If you do choose to extend the usage, be sure to change the pants more frequently and rinse them thoroughly before reusing.

It's important to note that improper care and infrequent washing can lead to the buildup of bacteria and odors, impacting the effectiveness and longevity of the pants. Always follow the washing instructions provided by the manufacturer, as they may vary based on the fabric and design of the period pants.

Properly washing and caring for your period pants will help ensure their durability and performance, allowing you to feel confident and comfortable throughout your menstrual cycle. By following the recommended practices, you can maintain the hygiene, absorbency, and lifespan of your period pants, making them a reliable and sustainable choice for managing your period.

Frequently Asked Questions

When it comes to washing period pants, there are a few important things to keep in mind. Understanding how to properly care for and clean your period pants can help prolong their lifespan and maintain their effectiveness. Here are some commonly asked questions about washing period pants:

1. How should I pre-treat period stains on my pants?

Before washing your period pants, it's essential to pre-treat any stains to ensure they are properly removed. Start by rinsing the pants in cold water to help prevent the stain from setting. Then, apply a stain remover or a bit of detergent directly to the stain and gently rub it in. Let it sit for a few minutes before washing.

Avoid using hot water for pre-treatment, as it can set the stain and make it more challenging to remove. Additionally, always check the care instructions provided by the manufacturer to ensure you're using the appropriate stain removal method for your specific period pants.

2. Can I wash period pants with other clothing items?

To maintain the effectiveness and longevity of your period pants, it's best to wash them separately from your other clothing items. This helps prevent the transfer of any residual blood or stains onto other garments. Washing them separately also allows you to use the appropriate settings and products specifically for your period pants.

However, if you prefer to wash your period pants with other clothing, make sure to sort them based on color and fabric type. Use a garment bag to protect them during the wash cycle and avoid using fabric softener, as it can reduce the absorbency of the period pants.

3. What temperature should I use when washing period pants?

When washing period pants, it's recommended to use cold or lukewarm water. Hot water can potentially damage the materials and elastic properties of the pants. Cold or lukewarm water is gentler on the fabric and helps prevent shrinkage and loss of absorbency.

Always check the care instructions provided by the manufacturer for specific temperature recommendations. Some period pants may have special requirements, so it's important to follow their guidelines to ensure proper cleaning and care.

4. Can I use fabric softener or bleach when washing period pants?

It's best to avoid using fabric softener when washing period pants. Fabric softeners can reduce the absorbency of the pants and affect their overall effectiveness. Additionally, fabric softeners may leave residue on the fabric, which can lead to discomfort or irritation when wearing the pants.

As for bleach, it's generally not recommended for period pants, as it can damage the fabric and elastic properties. Bleach can also discolor the pants or cause them to deteriorate faster. Stick to using mild detergents without bleach or harsh chemicals for optimal care.

5. How should I air-dry period pants?

Air-drying period pants is the best method to preserve their quality and shape. Avoid using a dryer, as high heat can damage the fabric and elastic components. To air-dry your period pants, lay them flat on a clean surface or hang them up using a clothesline or hanger.

Make sure to dry them in a well-ventilated area away from direct sunlight to prevent fading or discoloration. If necessary, you can also gently reshape the pants while they are still damp to ensure they retain their proper fit and form.



Period pants are a convenient and sustainable option for managing your menstrual flow. To properly wash period pants, follow these simple steps:

  • Start by rinsing the pants under cold water to remove any excess blood.
  • After rinsing, soak the pants in cold water for about 30 minutes to an hour to help remove any remaining stains.
  • Next, hand wash the pants using a gentle detergent. Avoid using harsh chemicals or bleach, as they can damage the fabric.
  • After washing, rinse the pants thoroughly with cold water until the water runs clear.
  • Finally, you can either hang the pants to dry or lay them flat. Avoid using a dryer as it may shrink or damage the fabric.

By following these steps, you can ensure that your period pants stay clean, fresh, and ready to use for your next cycle. Remember to always read and follow the care instructions provided by the manufacturer for the best results.
