Cleaning your private parts correctly comes down to one principle: gentle external washing with warm water, minimal soap, and no products inside the body. The details differ depending on your anatomy, but the goal is the same for everyone. You want to remove sweat, dead skin, and bacteria from skin folds without disrupting the body’s natural defenses.
How the Vagina Cleans Itself
The vagina is a self-cleaning organ. Beneficial bacteria called lactobacilli produce lactic acid and other antimicrobial compounds that keep the internal environment acidic, with a healthy pH between 3.8 and 4.5. That acidity fights off harmful bacteria and yeast on its own. Discharge is part of this process. It carries dead cells and microorganisms out of the body naturally.
This is why internal cleaning, including douching, is not just unnecessary but actively harmful. Women who douche once a week are five times more likely to develop bacterial vaginosis than women who don’t. Douching can also push existing bacteria upward into the uterus and fallopian tubes, potentially causing pelvic inflammatory disease. The takeaway is simple: nothing needs to go inside the vaginal canal to clean it.
Cleaning the Vulva
The vulva, which is the external area including the labia, clitoral hood, and the skin around the vaginal and urethral openings, does need regular washing. The CDC recommends washing your vulva and bottom every day. Here’s how to do it well:
- Use warm water. For most people, warm water alone is enough. If you prefer soap, choose one that’s unscented, paraben-free, and free of dyes.
- Wash the folds gently. Spread the labia and rinse between the skin folds where sweat and dead skin collect. Use your clean hands or a soft washcloth.
- Wipe front to back. After using the toilet, always wipe from the urethra toward the anus, not the other direction. This prevents gut bacteria from reaching the vaginal area.
- Pat dry rather than rub. Moisture trapped in skin folds encourages yeast growth. A gentle pat with a clean towel helps.
Avoid hygiene sprays, scented pads, scented tampons, perfumed soaps, and adult or baby wipes with fragrance. Even products labeled “gentle” or “mild” can contain perfumes that irritate vulvar skin. Regular soap typically has a high pH that can shift the vaginal environment and increase your risk of infection.
Cleaning the Penis
Daily washing with warm water and mild soap keeps the penis clean and prevents buildup of smegma, a whitish substance made of oils, dead skin cells, and moisture that collects under the foreskin or around the glans.
If you’re uncircumcised, gently pull the foreskin back as far as it comfortably goes. Wash underneath with soap and clean water using your hands or a washcloth, then rinse thoroughly. Slide the foreskin back into place when you’re done. Doing this daily should clear any smegma within a few days. For circumcised individuals, wash the shaft, glans, and the base of the penis where it meets the scrotum, paying attention to skin folds.
Don’t skip the scrotum. The skin there has many sweat glands and folds where bacteria thrive. Wash it the same way you’d wash the rest: warm water, mild soap, gentle hands.
Interestingly, both poor hygiene and over-washing can cause balanitis, an inflammation of the head of the penis. European dermatology guidelines list both as predisposing factors. The inflammation is essentially irritation between two skin surfaces with bacterial or fungal overgrowth. If balanitis develops, avoid soap on the inflamed area until it heals, and keep the glans dry by leaving the foreskin retracted briefly after washing.
Hygiene for Children
Parents sometimes wonder about cleaning under a young child’s foreskin. In boys, the foreskin is naturally fused to the glans at birth and separates on its own over time. Never force it back. Once it retracts naturally, gently pull it back during baths to wipe away any smegma with mild soap and water. Cleaning once or twice a week is enough for children.
For girls, wash the vulva gently with water during bath time, always moving front to back. Avoid bubble baths and scented products, which are common causes of irritation in young children.
After Exercise and Sweating
Sweat itself doesn’t smell much, but when it sits in warm, enclosed areas like the groin, bacteria break it down quickly. The moisture also creates ideal conditions for yeast overgrowth. Change out of sweaty underwear and workout clothes as soon as you can after exercise. If you can’t shower right away, even switching into dry underwear helps.
Bring a change of clothes to the gym. If you’re out during the day and feel uncomfortably sweaty, unscented wipes can help clean the outer skin. For most people, bathing once or twice daily with water and mild soap is enough to manage sweat and odor.
During Your Period
Menstruation doesn’t require any special cleaning products, but it does call for a bit more attention to routine. Wash your vulva with water at least once a day, and always wash your hands before and after changing a pad, tampon, or menstrual cup. Blood that stays on the skin can cause irritation, so rinsing the vulvar area when you change products is a good habit.
The vagina’s self-cleaning system stays active during your period. Resist the urge to use internal washes or scented products to mask menstrual odor. These disrupt pH balance and increase the risk of both yeast infections and bacterial vaginosis.
After Sex
Urinating shortly after sex helps flush bacteria away from the urethra, which reduces the risk of urinary tract infections. This applies to everyone but is especially relevant for people with vulvas, who have a shorter urethra. A gentle external rinse with warm water afterward is all you need. Avoid soaps or wipes with fragrance, and be cautious with lubricants. Water-based lubricants can dry out during sex and cause tiny tears in delicate tissue, so using enough product and reapplying as needed matters.
Products to Avoid
The genital skin is thinner and more absorbent than skin on the rest of your body, which makes it more reactive to chemicals. Steer clear of these:
- Douches. No medical organization recommends them for routine use.
- Scented soaps, body washes, and bubble baths. Fragrance chemicals are among the most common causes of contact irritation in the genital area.
- Feminine deodorant sprays. These mask odor temporarily while introducing irritants.
- Scented pads and tampons. The fragrance sits against your skin for hours, increasing the chance of a reaction.
- Talcum powder. It can clump in skin folds and cause irritation.
If you notice a strong or unusual odor that doesn’t improve with regular external washing, that’s worth paying attention to. Odor changes often signal a shift in vaginal bacteria or an infection, and no product will fix the underlying cause.
