If you’ve ever noticed light or “bleach-like” patches on your underwear, you’re not alone—and there’s no reason to worry. These marks aren’t caused by detergent or poor hygiene but by your body’s natural chemistry.
Why Does Vaginal Discharge Leave Bleach-Like Marks?
The vagina maintains a slightly acidic pH, usually between 3.8 and 4.5. This acidity is essential for health, as it prevents harmful bacteria from thriving and helps protect against infections. However, when vaginal discharge comes into contact with certain fabrics, the acid can break down dyes or fibers, leaving lighter spots on underwear. The effect is especially noticeable on darker fabrics, where the contrast is more visible.
Addressing the Stigma Around Vaginal Health
Far from being a problem, this reaction is a sign of a healthy, self-cleaning vagina. As Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynaecologists explains, natural discharge contains beneficial bacteria that protect and balance the vaginal environment.
Tips for Managing and Embracing Your Body’s Natural Processes
While the presence of “bleach” patches on underwear is nothing to worry about, there are steps you can take to care for your vaginal health and reduce discoloration if desired:
- Choose Breathable Fabrics: Opt for underwear made of natural, breathable materials like cotton. These fabrics are less likely to trap moisture and are gentler on sensitive skin.
- Avoid Harsh Products: Stay away from scented soaps, douches, or other products that claim to “clean” the vagina. Remember, your body is already doing that for you.
