Timing Is Key: Don’t Let Your Period Underwear Sit in a Hamper

Leaving menstrual underwear unwashed for hours—or worse, days—can cause stains to set, odor buildup, and bacteria growth. For best results:

• Rinse out immediately

• Store damp panties in a waterproof bag or container if you can’t wash right away

Retailers: This is a great education point for your customers—include simple care cards in every package.

Period Underwear (Not Limited to LYNMISS): Care FAQs

• Does Period Underwear Need to Be Rinsed Before Washing?

Yes. Rinsing in cold water helps release blood and prepare the fabric for a gentle wash.

• Should You Stick with a Delicate Cycle?

Absolutely. A gentle cycle with cold water preserves the integrity of absorbent layers and reduces wear.

• Are There Specific Steps for Removing Odor in Period Pants?

Soaking briefly in cold water with white vinegar or baking soda can help neutralize persistent odors.

• What Type of Detergent Should You Use?

Use mild, unscented detergent. Avoid harsh chemicals, enzymes, or softeners, as they damage the absorbent layers.

• Fabric Softener with Period Underwear: Yay or Nay?

Nay. Fabric softeners coat fibers and block absorbency. Always skip them.

• How to Treat Blood Stains That Don’t Lift Out in a Regular Wash?

Try gently scrubbing with baking soda paste or oxygen-based stain removers—no bleach or peroxide.

• What About Machine Washing Period Panties With Other Items?

It's generally fine, especially if you rinse first. Stick with darks and avoid mixing with delicate whites.
