Have you ever pulled your underwear out of the laundry only to notice strange, pale marks that look like they’ve been bleached? If so, you’re not alone—and no, it’s probably not your detergent’s fault.
These mysterious “bleach stains” can actually be your body’s way of telling you something about your health and hygiene. Let’s break it down.
1. It’s All About pH Balance
The most common cause of these discolorations is your body’s natural vaginal discharge. Healthy vaginal fluids are slightly acidic, with a pH ranging from 3.8 to 4.5. This acidity can interact with dyes in fabrics, especially in darker underwear, causing fading or “bleached” spots over time.
It’s completely normal—and even a sign of a healthy, self-cleaning system.
2. When It’s Not So Normal
While mild staining is expected, if you notice an unusual color (like green or gray), a strong odor, or a chunky texture, it might indicate an infection like bacterial vaginosis or a yeast infection. In that case, it’s worth talking to a healthcare provider.
3. Fabric Matters More Than You Think
Synthetic underwear can react more strongly to acidic discharge, while natural fibers like cotton tend to handle it better and allow the area to breathe. Switching to cotton underwear or panty liners can reduce staining and promote better hygiene.
