There are an infinite number of reasons why the internet and the information it contains are invaluable.

It may be the greatest invention of the last hundred years since there is an infinite pool of shared knowledge, even though the benefits it provides to our everyday lives are endless.

With the right resources, you can learn anything you want to know about any subject. A few keystrokes or clicks of the mouse can reveal answers to mysteries that have eluded scientists for decades.

Many long-held misconceptions have been disproven in recent years thanks to the internet, and many once-secret tips and tricks have become general knowledge.

For instance, have you ever pondered the reason behind your underwear taking on a bleach spot appearance? If so, you’re evidently not alone; women are asking this very question online in an effort to get some sort of response.

And solutions were discovered. Despite what some may have thought, those colored patches are totally unrelated to your machine.

Contrary to popular belief, the vagina’s natural pH levels are the real culprit behind these “bleach” patches.

Before we continue, we want to make it clear that this is completely normal. Instead, it’s a good indicator if you notice those patches on your underpants. The acidity or alkalinity of a liquid or substance can be determined by looking at its pH level. One useful post on Twitter states:

Because the vagina is acidic (with a pH range of 3.8-4.5), it is perfectly common to find lighter spots in a woman’s underwear or knickers now that everyone knows. I guess it’s time to stop thinking about it as a consequence of not washing enough. Actually, the ability to bleach fabric indicates a healthy vagina.

Natural secretions serve as a self-cleaning mechanism for the vagina, according to Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynaecologists. The good microorganisms in it help keep it safe.

The typical vaginal pH, according to the NIH, is rather acidic, falling anywhere between 3.8 and 5.0 on the scale from 7 (the neutral pH) to 0 (very acidic).

Having clear or white vaginal discharge is completely normal and healthy for women, according to Dr. MacKay, but infections can develop when this natural balance is upset.
