Period underwear, which is otherwise known as menstrual underwear or period panties which is used to absorb menstrual flow and gives comfort and leakproofness, unlike traditional pads and tampons. These innovative garments are designed with multiple layers of absorbent and leak-resistant fabric, allowing them to be worn without additional menstrual products like pads or tampons—or in combination with them for added protection.
Why Proper Period Underwear Care Matters?
Prevents Bacterial Growth and Infections
Menstrual blood is a bodily fluid, and if it’s left to sit in fabric for too long without proper washing, bacteria can multiply. This can lead to vaginal irritation or even infections.
Extends the Lifespan of the Underwear
With correct menstrual underwear cleaning, high-quality period panties can last for years. Avoiding harsh chemicals and high heat keeps the fabrics and absorbent layers intact.
Maintains Absorbency and Comfort
Improper washing—especially with fabric softeners or high heat—can damage the absorbent core, making your underwear less effective at preventing leaks and less comfortable to wear.
Ensures Stain-Free and Odour-Free Wear
Stains and odours develop when period panties aren’t rinsed or cleaned correctly. Good hygiene habits help keep them looking and smelling fresh after each use.
Do’s of Period Underwear Care
Keeping your period panties in top condition is easier than you think. Follow these essential care tips to keep them clean, comfy and long-lasting.
1. Rinse immediately after use in cold water
As soon as you take off your period underwear, rinse them under cold water. This helps to prevent stains from setting and removes most of the blood before you start washing. Avoid hot water at this stage, as it can cause stains to cling to the fabric.
2. Hand Wash or Use a Gentle Machine Wash
Hand washing is often the safest method, especially for delicate fabrics. Use a mild detergent and gently agitate the underwear in lukewarm or cold water. If you prefer machine washing, place them in a mesh laundry bag and select a delicate cycle.
3. Air dry completely (Avoid damp storage)
After washing, always air dry your period underwear. Hang them up in a well-ventilated space or lay them flat on a drying rack. Ensure they’re fully dry before storing to avoid mildew, bacteria, or bad odours.
4. Use Mild, Fragrance-Free Detergents
Harsh detergents, artificial fragrances, and enzymes can irritate sensitive skin and degrade fabric. Choose a mild, fragrance-free detergent that’s safe for intimate wear.
5. Store in a Clean, Dry Place
Once your underwear is dry, store it in a cool, dry drawer or container. Keeping them in a sanitary environment maintains hygiene between uses.
6. Follow Brand-Specific Washing Instructions
Every brand has its own material blend and absorbent technology, so always check the label or packaging instructions for care tips specific to your pair.
Don’ts of Period Underwear Care
Just as there are essential practices to follow, there are also common mistakes that can ruin your period panties. Here’s what to avoid:
Don’t Use Hot Water
Hot water can set blood stains into the fabric and damage the absorbent layers. Always rinse and wash your menstrual underwear in cold or lukewarm water.
Don’t Use Fabric Softeners or Bleach
These products can break down the absorbent fibres and reduce the effectiveness of the underwear. Bleach also causes discolouration and can irritate your skin.
Don’t Iron or Tumble Dry on High Heat
Heat can warp or melt certain synthetic fibres used in period underwear. Never iron them or put them in a hot dryer. Use air drying or low-heat settings only if you must use a machine.
Don’t Delay Rinsing for Hours After Use
Leaving soiled underwear unwashed for hours allows bacteria and odours to develop. Rinse them as soon as possible after removing to keep them clean and hygienic.
Don’t Share Menstrual Underwear
Period panties are personal hygiene items, just like toothbrushes or regular underwear. Never share them, even if they’ve been washed, to avoid the risk of infection.
Don’t Store Damp Underwear
Storing your period underwear while still damp can lead to mould growth and unpleasant odours. Always wait until they are completely dry before storing them away.
Pro Tips for Long-Lasting Comfort
To make the most of your period underwear and ensure they stay comfortable and effective, consider these extra tips:
Rotate Between 2–3 Pairs
Having multiple pairs on hand allows each one to fully dry and rest between wears, extending their lifespan and giving you better flexibility during your cycle.
Use a Laundry Bag
When machine washing, protect your underwear by placing it in a mesh laundry bag. This reduces fabric stress and prevents snagging on other clothing.
Sun-Dry Occasionally for Natural Disinfection
Once in a while, sun-dry your period panties. Sunlight acts as a natural disinfectant and helps eliminate lingering bacteria and odours.
Keep Backup Options
For heavy flow days or emergencies, it’s wise to keep a backup pair of disposable pads or tampons in your bag. This ensures you’re always covered—even if you’re washing your period underwear.
Is It Safe to Wear Period Panties Every Day?
It is completely safe to wear period panties every day. But it solely depends on the individual’s comfort. Women who find it comfortable can wear them at any time they wish. Period underwear can be a comfortable, eco-friendly, and cost-effective option for daily wear; however, it's essential to consider individual needs, flow levels, and personal hygiene practices.
