Quick Answer

To make your period underwear last, rinse them in cold water immediately after wearing, then wash on a gentle cycle in cold water with mild detergent, and always air dry. Avoid fabric softeners, bleach, and high heat, as these can break down the absorbent layers and elastics.

Period underwear is an investment in comfort and sustainability, so it’s worth a few extra minutes of care to keep them performing wash after wash. With the right routine, you can extend their lifespan, maintain absorbency, and keep them looking and feeling great.

Whether you're new to reusable period pants or a seasoned pro, understanding how to wash and dry them properly is key. Here’s a practical guide to caring for your Modibodi underwear so they stay reliable for years to come.

Why Proper Care Matters

Period underwear relies on multiple layers to absorb moisture and lock it away. These layers are delicate and can be damaged by harsh washing methods. Using hot water, fabric softeners, or bleach can break down the fibers, reducing absorbency and causing leaks over time. Similarly, high-heat drying can warp elastics and compromise the fit.

By following simple care instructions, you protect your investment and ensure that your underwear remains comfortable and effective. Plus, proper care reduces the need for replacements, which is better for your wallet and the planet.

  • Always check the care label on your specific pair, as different styles may have slightly different requirements.

The Do's and Don'ts of Washing

The golden rule is to rinse your period underwear in cold water as soon as possible after wearing. This prevents stains from setting and helps keep the fabric fresh. You can either rinse them in the sink or simply run them under cold water in the shower.

When it comes to machine washing, place them in a mesh laundry bag to protect them from snagging. Use a gentle cycle with cold water and a mild, fragrance-free detergent. Avoid chlorine bleach, fabric softeners, and dryer sheets, as these can clog the absorbent layers and reduce effectiveness.

  • If you're hand washing, use a gentle detergent and avoid wringing or twisting the fabric, which can damage the absorbent core.

Drying and Storing

Air drying is the best way to preserve the elastic and absorbency of your period underwear. Hang them or lay them flat in a well-ventilated area, away from direct sunlight to prevent fading. Never put them in the dryer, as high heat can break down the water-repellent layer and elastics.

Once dry, store them in a cool, dry place. Avoid folding them in a way that creases the absorbent panel, as this can cause permanent lines that might affect comfort. Keeping them flat or rolled will help maintain their shape.

  • If you're storing them for a longer period, ensure they are completely dry to prevent mildew or odors.

Step-by-Step Care Routine

  1. Rinse in cold water: As soon as you remove your period underwear, rinse them under cold running water to remove blood and prevent stains. You can do this in the sink or while you're in the shower. Checkpoint: The water runs clear – this means most of the blood is out.
  2. Wash gently: Either hand wash with a mild detergent or machine wash in a mesh bag on a gentle cycle with cold water. Use a detergent that's free of fragrances, bleach, and fabric softeners. Checkpoint: Avoid wringing or twisting – this can damage the absorbent core.
  3. Air dry completely: Lay flat or hang to dry in a well-ventilated area, away from direct sunlight. Do not use a dryer, as heat can break down elastics and absorbent layers. Checkpoint: Ensure they're fully dry before storing to prevent mildew.
