The internet — with its endless flow of information — has become one of the most invaluable tools of modern times. Its benefits are countless, but perhaps its greatest strength lies in its ability to offer a shared, limitless pool of knowledge.
These days, there’s no question too strange or topic too obscure that you can’t find an answer for online. Mysteries that might’ve remained unsolved for generations can now be explained in seconds with a quick search and a few clicks.
Over the years, countless old myths have been debunked thanks to the internet, while life hacks, facts, and practical wisdom that were once passed down quietly between small groups have become widely known.
Take, for example, a question that’s popped up more than a few times: why do certain parts of underwear sometimes look like they’ve been bleached? If you’ve noticed it and wondered, you’re not alone. Plenty of people have taken to the internet seeking answers.
And, as it turns out, there’s a perfectly natural explanation. Despite what some might suspect, it has nothing to do with your washing machine or detergent.
The cause of these so-called “bleach” patches is actually the natural pH levels of the vagina.
Before anyone worries — this is completely normal and healthy. In fact, it’s a sign that your body is doing exactly what it’s meant to.
For those unfamiliar, pH levels measure how acidic or alkaline a substance is. The vagina naturally maintains a mildly acidic environment, typically with a pH between 3.8 and 4.5. This acidity can sometimes lighten or affect the color of fabric over time.
According to one post on Twitter:“Now that everyone knows, it’s totally normal to notice lighter patches in women’s underwear due to the vagina’s acidic nature. It’s not poor hygiene — in fact, a healthy vagina is one that can bleach fabric.”
So, if you’ve noticed it before, rest assured — it’s a completely natural and healthy part of your body’s biology.

Dr. Vanessa MacKay from the Royal College of Obstetricians and Gynaecologists explains:
“The vagina has its own natural self-cleaning process through regular secretions. It also contains beneficial bacteria that help keep it healthy and protected.”
According to the National Institutes of Health, the typical vaginal pH falls between 3.8 and 5.0 — making it moderately acidic compared to the neutral pH level of 7.
Dr. MacKay also notes that it’s completely normal for women to have clear or white vaginal discharge. In fact, it’s a healthy sign. However, disrupting this natural balance can lead to irritation or infections.
