Learn the simple steps to wash and maintain reusable period underwear. Extend their life with proper care, avoid common mistakes, and keep them fresh.
Quick answer
Rinse your period underwear in cold water immediately after wearing, then machine wash on a gentle cycle with mild detergent. Avoid fabric softeners and high heat drying to preserve absorbency and elasticity.
Why proper care matters for period underwear
Reusable period underwear is an investment in comfort and sustainability. The absorbent layers and leak-resistant panels are designed to last through many cycles, but only if you treat them right. Harsh detergents, high heat, and fabric softeners can break down the fibers and reduce effectiveness over time.
Step-by-step care routine
- Rinse immediately after use: As soon as you remove your period underwear, rinse it under cold running water until the water runs mostly clear. Cold water prevents blood from setting into the fabric fibers. Common mistake: using hot water can set stains and damage the absorbent core.
- Machine wash on a gentle cycle: Place your rinsed underwear in a mesh laundry bag for protection. Wash on a cold, gentle cycle with a mild, fragrance-free detergent. Avoid bleach, fabric softeners, and stain removers with harsh chemicals. Checkpoint: skip the spin cycle if possible to reduce wear on the elastic bands.
- Air dry away from direct heat: Hang your period underwear to dry in a well-ventilated area. Do not put them in the dryer or on a radiator. High heat can melt the waterproof layer and shrink the fabric. Verdict: line drying preserves the fit and function far longer than machine drying.
