How to get rid of Knix underwear smell reddit?

Many folks on Reddit and other forums share this struggle — period underwear like Knix can sometimes develop a stubborn smell if not cared for just right. Here’s the consensus on what works:

1. Rinse Immediately with Cold Water

Right after wearing, rinse your Knix underwear in cold water to flush out sweat, blood, and any fluids. Avoid hot water here because it can set odors.

2. Soak in Baking Soda or Vinegar

  • Soak your underwear for 20-30 minutes in cold water with 1-2 tablespoons of baking soda OR

  • Use a mix of cold water and white vinegar (1 cup vinegar per gallon of water) to help neutralize odors.

3. Use a Mild Detergent

Wash with a fragrance-free, gentle detergent. Avoid fabric softeners or bleach, which can damage the absorbent layers.

4. Double Wash if Needed

If smell persists, run a second wash cycle or hand wash again with detergent and baking soda.

5. Air Dry Completely

Let your underwear dry fully in fresh air—never tumble dry or iron, as heat breaks down odor-blocking fabrics.

6. Occasional Deep Clean

Every so often, you can do a deep clean by soaking in oxygen-based bleach (like OxiClean) following package instructions, then wash as usual.
