Making the switch to period underwear is a step towards more comfortable, sustainable, and stress-free periods. But one question we hear often is:
"How do I wash my period panties properly?"
The good news? Caring for your One:28 period underwear is incredibly simple. With the right washing routine, your period panties will stay fresh, absorbent, and effective for years to come. Proper care helps preserve the performance of the absorbent layers while ensuring maximum comfort every cycle.
Step 1: Rinse in Cold Water After Use
Once you've worn your period underwear, rinse it under cold running water until the water runs mostly clear.
Cold water helps remove menstrual fluid and prevents stains from setting into the fabric. It's a quick step that makes a big difference in maintaining the absorbency and longevity of your underwear.
Step 2: Wash with a Mild Detergent
After rinsing, you can either:
- Hand wash your period panties, or
- Machine wash them with your regular laundry
Use a mild detergent and choose a gentle wash cycle whenever possible. Harsh chemicals can break down the technical layers designed to absorb and lock in moisture, so gentler is always better.
Step 3: Air Dry Completely
Once washed, hang your period underwear to air dry.
Allowing your panties to dry naturally helps protect the absorbent technology and keeps the fabric in great condition. Before storing or wearing them again, make sure they are completely dry.
What to Avoid When Washing Period Underwear
To keep your One:28 period panties performing at their best, avoid:
Bleach
Bleach can damage the fabric and reduce the effectiveness of the absorbent layers.
Fabric Softeners
Fabric softeners leave a coating on the fibres that can interfere with absorbency over time.
High-Heat Drying
Tumble dryers and high temperatures can damage elastic fibres and impact the performance of your period underwear. Air drying is always the safest option.
Why Proper Care Matters
One:28 period underwear is designed to be reused again and again. With proper care, your underwear can maintain its comfort, absorbency, and leak protection across countless cycles. Taking a few extra minutes to rinse, wash gently, and air dry helps you get the most out of every pair while reducing waste from disposable period products.
