Have you ever wondered why your underwear sometimes appears to have bleach stains? Many women have, and this question has sparked much discussion online.
Surprisingly, these patches have nothing to do with your washing machine. Instead, they are caused by the natural pH levels of the vagina.

These patches indicate a healthy vagina. pH levels measure the acidity or alkalinity of a substance, and as one informative Twitter post explains:
“Now that everyone is aware, it’s completely normal to discover lighter patches in a woman’s underwear or knickers due to the acidic nature of the vagina, with a pH range of 3.8-4.5. So, I suppose it’s time to abandon the notion of it being a result of poor hygiene. In fact, a healthy vagina is one that can bleach the fabric.“
