Your Period Underwear Lost it's Absorbency? Try These Fixes

You made the switch to period underwear—a sustainable, comfortable game-changer. But what if your go-to pair isn’t as absorbent as it used to be? Don’t panic. This doesn’t mean the end of your favorite undies. With a few simple tricks, you can restore their absorbency and keep them in top shape for the long run.

Why Does Period Underwear Lose Absorbency Over Time?

Gotyu period underwear can hold up to six tampons’ worth of fluid. But if it’s not working like it used to, here’s why
  • Residue buildup from detergent or hard water clogs the fibers.
  • Fabric softener creates a barrier that repels moisture.
  • Improper washing or drying can affect the material’s performance.
But there’s an easy fix.

Absorbency Boost: Bring Your Period Underwear Back to Life

You know that fresh, just-washed feeling when you put on your favorite clothes? You can get that same refresh for your period underwear. The secret is washing soda. This natural powerhouse breaks down buildup and restores absorbency—without harsh chemicals or color fading.

How to do it:

  1. Rinse your underwear in cold water until no blood is visible.
  2. Mix hot water with one tablespoon of washing soda.
  3. Let the water cool down to lukewarm.
  4. Soak your underwear for a few hours or overnight.
  5. Wash as usual (see below), and your underwear will be as good as new.
Washing soda is available in drugstores, eco-friendly shops, or online.

How to Keep Your Period Underwear Absorbent for Longer

  • Rinse after each wear – Cold water is essential. Rinse in the sink or shower until the water runs clear.
  • Machine wash – Max 40°C (104°F), mild detergent, no fabric softener or bleach.
  • Hand wash – Use gentle soap to protect the fibers.
  • Use a laundry bag – Helps maintain the fabric and elasticity.
  • Use a suitable Detergent: Find out which ones are best to make your undies last long here.

Drying: The Key to Long-Lasting Absorbency

  • Line dry whenever possible—sunlight is naturally antibacterial and helps maintain freshness.
  • Drying time: Period underwear takes 10-12 hours to dry because of its multi-layered design—the same layers that make Gotyu leak-proof.
  • Avoid the dryer: Heat damages fibers and reduces absorbency.

Accidentally Used the Dryer?

No need to worry if it happened once. But repeated drying can wear down the absorbent layers over time. If it happens, wash again and air dry.
