How to Wash Period Underwear
If you are new to period underwear you might be wondering how to wash period underwear properly.
You’ve made the switch to reusable (go you 👏), but now you’re standing at the sink like… am I doing this right?
And if you’re not washing your period underwear or period undies properly? It can affect absorbent layers, freshness, and how long they last.
The good news? It doesn’t have to be complicated.
Why Washing Period Underwear Properly Matters
Period underwear is designed with absorbent layers and high-performance fabrics that lock in menstrual fluid while keeping you dry.
But those same layers need the right care.
Washing your period underwear properly helps:
-
Maintain absorbency
-
Prevent odours
-
Extend the life of your period panties
-
Keep everything feeling fresh and clean
Better care = better performance. Simple.
How to Wash Period Underwear (Step-by-Step Guide)
If you’ve been Googling “how to wash period underwear”, here’s your go-to routine.
Step 1: Rinse, Soak or Hand Wash First
After wearing, rinse your period underwear or period undies in cold water or leave them to soak (pro tip: in our opinion, the Strucket Mini is hands-down the best tool for soaking!).
This helps remove period blood, blood stains, and menstrual fluid before they set.
Step 2: Wash Gently in the Washing Machine
Once rinsed, pop your period underwear into the washing machine.
-
Use a gentle or delicate cycle / wash cycle
-
Choose a mild laundry liquid or delicate detergent (eco-friendly detergents are a great option)
-
It also helps to place them in a laundry bag, mesh laundry bag, or delicates bag
🚫 Skip bleach or fabric softener — it can damage absorbent fabrics and reduce performance over time.
Step 3: Air Dry for Best Results
When it comes to drying, patience pays off.
-
Air dry or line dry your underwear
-
Avoid using a tumble dryer.
Heat can damage absorbent layers and leakproof design features.
