The short answer: you wash the outside (the vulva), not the inside (the vagina). The vagina is a self-cleaning organ that maintains its own environment, and the best thing you can do is leave it alone. Your vulva, the external skin and folds you can see, just needs warm water and, at most, a plain fragrance-free soap once a day.
That distinction between inside and outside is the single most important thing to understand about genital hygiene. Everything else follows from it.
Vulva vs. Vagina: Why It Matters
The vulva is everything on the outside: the outer and inner lips (labia), the clitoral hood, and the vestibule, which is the area between the inner lips where both the vaginal opening and the urethral opening are located. The vagina itself is an internal canal, roughly ten centimeters long, that you cannot see from the outside. It connects the vestibule to the cervix.
When people say “wash your vagina,” they almost always mean the vulva. This isn’t just a technicality. The vagina has its own ecosystem of beneficial bacteria, predominantly Lactobacillus species, that produce lactic acid and keep the pH below 4.5. That acidity is what prevents harmful bacteria and yeast from taking over. Your vaginal lining sheds and renews itself continuously, and the discharge you see is part of that cleaning process. Putting soap, water, or anything else inside disrupts the chemistry that keeps you healthy.
How to Wash, Step by Step
Wash your vulva once a day with clean hands and lukewarm or cool water. No washcloth is necessary, and skipping one actually reduces your exposure to bacteria that can collect in damp fabric. The American College of Obstetricians and Gynecologists (ACOG) says plain, fragrance-free soap is fine on the outer vulva. If you’re experiencing any irritation, drop the soap entirely and use only water on the inner folds. Water alone is perfectly adequate.
Always wash from front to back, vulva first, then toward the anus. This prevents intestinal bacteria from reaching the vaginal or urethral area. After rinsing, gently pat dry with a clean towel rather than rubbing. If you’re prone to lingering moisture, a hair dryer on a cool setting works well.
That’s it. No special technique, no internal rinsing, no elaborate routine.
Why Douching Is Harmful
Douching means flushing water or a solution into the vaginal canal. It’s one of the most reliably harmful things you can do to your vaginal health. The World Health Organization identifies douching as a factor that increases the risk of bacterial vaginosis, a condition where harmful bacteria overtake the protective ones. The CDC is equally direct: washing or using chemicals inside the vagina disrupts your natural pH and can cause yeast infections or bacterial vaginosis.
Even “gentle” or “pH-balanced” douches interfere with the Lactobacillus colonies that protect you. Once those colonies are weakened, it becomes easier for infections to take hold, which can create a cycle where you douche more because something feels off, making the problem worse.
Products to Avoid
Scented soaps, body washes, and “feminine hygiene” products are the most common sources of vulvar irritation. Fragrance is a broad category that can contain dozens of undisclosed chemicals, and the skin of the vulva is thinner and more absorbent than skin elsewhere on your body.
Beyond fragrance, ingredients flagged as concerns in intimate care products include parabens (ethylparaben, methylparaben, propylparaben), formaldehyde-releasing preservatives, sodium laureth sulfate, and antibacterial agents like benzalkonium chloride. You don’t need to memorize this list. The simplest rule: if a product is scented, marketed specifically as a “feminine wash,” or contains a long ingredient list, you’re better off without it. A basic, unscented soap or just water will do more for your health than any specialized product.
The same applies to scented tampons, pads, and toilet paper. Stick with unscented versions.
After Exercise and Sweating
The vulvar area has a high concentration of sweat glands, and trapped moisture creates conditions where yeast thrives. The most effective thing you can do after a workout is change out of sweaty clothes as soon as possible. If you go to a gym, bring a change of underwear and bottoms.
If you can’t shower right away, unscented wipes can help remove sweat. Avoid antibacterial wipes, which can disrupt your natural microbiome the same way internal products do. When you do shower, the same rules apply: warm water, optional mild soap on the outer vulva, pat dry.
During Your Period
Menstruation doesn’t change the basic approach. The CDC recommends washing your vulva daily with water during your period, wiping front to back, and using unscented menstrual products. You may feel more comfortable rinsing off more than once a day, and that’s fine as long as you’re not using harsh soap each time.
Change pads, tampons, or menstrual cups at the intervals recommended for each product. Blood sitting against the skin can cause irritation, so regular changes matter more than extra washing.
What Underwear and Clothing Help
White, all-cotton underwear allows air circulation and wicks moisture away from the skin. Nylon and other synthetic fabrics trap heat and dampness, even styles marketed as having a “cotton crotch panel.” If you deal with chronic dampness, keeping an extra pair of cotton underwear to change into midday can make a noticeable difference.
Remove wet swimsuits or workout clothes promptly. Sleeping without underwear or in loose-fitting shorts gives the area a chance to dry out overnight.
When Discharge Signals a Problem
Normal discharge varies throughout your menstrual cycle. It can be clear, white, or slightly yellowish, and it may be thin or somewhat stretchy. It generally has a mild smell or no smell at all. Changes to watch for:
- Thick, white, cottage cheese-like discharge with itching or swelling: typical of a yeast infection.
- Gray or white discharge with a fishy smell: characteristic of bacterial vaginosis.
- Green, yellow, or gray bubbly or frothy discharge: a possible sign of trichomoniasis, a sexually transmitted infection.
These conditions are common and treatable, but they won’t resolve with more washing. In fact, increasing how aggressively you clean in response to unusual discharge is one of the most common ways people make the situation worse. If your discharge changes in color, texture, or smell, that’s your body telling you the internal balance has shifted, and treatment addresses the cause rather than the symptom.
