Bleach-like stains on dark underwear may look alarming, but they’re usually completely normal. The vagina’s natural acidic pH helps protect against harmful bacteria and can gradually lighten fabric dyes over time.
These marks are not a sign of poor hygiene. However, if you notice unusual discharge, a strong odor, itching, burning, or pain, consult a healthcare provider.
In most cases, these stains are simply a harmless sign of healthy body chemistry.
