If you’ve ever noticed light or “bleach” spots on your underwear, don’t worry—this is entirely normal. These spots are caused by the vagina’s natural pH levels, which are moderately acidic (typically 3.8–5.0).
The acidity comes from healthy bacteria that protect the vaginal area and maintain its self-cleaning mechanism. This natural process can sometimes bleach the fabric of underwear, leaving lighter spots.
Dr. Vanessa MacKay from the Royal College of Obstetricians explains that clear or white discharge is part of this healthy process. While it’s no cause for alarm, disruptions in the pH balance could lead to infections.
Remember, these “bleach” spots are a sign of a healthy body, not poor hygiene.
