The internet is an incredible tool, offering a vast amount of knowledge at our fingertips.
While its benefits seem endless, perhaps its greatest strength lies in being a limitless source of shared information, making it one of the most revolutionary inventions of recent centuries.
With the right search, you can find answers to virtually any question. What once remained unsolved for decades can now be uncovered within seconds, thanks to a few keystrokes and clicks.
Just as life hacks and practical advice have become widely accessible—once reserved for only a select few, the internet has also debunked many long-standing myths.
For example, have you ever wondered why your underwear sometimes develops mysterious bleach-like stains? If so, you’re not alone, many women have turned to the internet in search of answers.

And they found the answer. Contrary to some misconceptions, those discoloration patches have nothing to do with your computer.
According to reports, these “bleach” stains are actually caused by the vagina’s natural pH levels.

Before we go any further, let’s emphasize once again, there’s absolutely no reason for concern. In fact, noticing these lightened spots on your underwear is actually a sign of good vaginal health.As many know, a substance’s pH level determines how acidic or alkaline it is. A widely shared tweet explains it best:
“Now that everyone knows, it’s completely normal to find lighter patches on a woman’s underwear due to the acidic nature of the vagina, which has a pH range of 3.8-4.5. So, let’s put to rest the myth that it’s caused by poor hygiene. In reality, a healthy vagina is one that’s acidic enough to bleach fabric.”
Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynecologists confirms that the vagina has a self-cleaning system, naturally maintaining its health with the help of beneficial bacteria.
According to the National Institutes of Health, vaginal pH typically ranges from 3.8 to 5.0, making it more acidic than the body’s neutral pH of 7.
Dr. MacKay further explains, “Disrupting this natural balance can lead to infections, but it’s completely normal and healthy for women to have clear or white vaginal discharge.”
