Cleaning your belly button is simple: mild, fragrance-free soap and warm water, applied with a finger or soft cloth, is all most people need. Despite how straightforward that sounds, the navel is one of the most overlooked spots during a shower, and skipping it can lead to buildup, odor, and occasionally infection.
Why Your Belly Button Gets Dirty
Your navel is a small, sheltered pocket of skin that collects everything it touches: dead skin cells, sweat, lint from clothing, and natural oils. A landmark microbiome study from North Carolina State University found over 2,300 bacterial species living across just 60 people’s belly buttons. Only eight of those species were common enough to show up in more than 70% of participants. The rest were rare, sometimes unique to a single person.
That microbial diversity is normal and mostly harmless. But when dead skin and oils accumulate without regular washing, they feed bacteria and yeast, creating the musty smell some people notice. Deep, concave “innie” navels are especially prone to trapping debris because they’re harder to reach and don’t get rinsed passively the way flatter skin does.
How to Clean an Innie Belly Button
The best approach is the simplest one. Dermatologists at the Cleveland Clinic recommend plain soap and water over any specialty product. Use a mild, fragrance-free soap to avoid irritating the thin skin inside the navel. Here’s a practical routine:
- In the shower: Lather a small amount of soap on your fingertip or a soft washcloth. Gently work it into the folds of your navel, rotating to reach the sides and bottom.
- Rinse thoroughly: Let warm water flush the soap out completely. Leftover soap residue can dry out the skin and cause irritation.
- Dry it well: Pat the inside gently with a clean towel or cloth. Moisture left sitting in a deep navel creates the warm, damp environment yeast loves.
If you notice stubborn buildup that soap alone doesn’t loosen, you can dip a cotton swab in warm soapy water and gently work it around the inside. Avoid scraping or picking at the skin. Doing this once or twice during your regular shower routine each week is enough for most people, though daily cleaning is fine if you’re active or sweat heavily.
How to Clean an Outie Belly Button
Outies are easier to clean because the skin is exposed rather than folded inward. The same soap-and-water approach works. Lather around and behind the protruding skin, paying attention to the crease where the outie meets the surrounding abdomen. That crease can still trap sweat and lint. Rinse and dry the same way you would an innie.
What Happens When You Don’t Clean It
Neglecting your navel long enough can lead to a few distinct problems, ranging from mildly unpleasant to genuinely uncomfortable.
Navel Stones
When debris like dead skin, oil, and lint accumulates in a deep belly button over months or years, it can compact into a small, hard mass called a navel stone (omphalolith). These are typically dark brown or black, dry to the touch, and resemble a large blackhead sitting in the opening of the navel. Small ones may go unnoticed. Larger ones can become visible and occasionally cause irritation or a foul smell.
You shouldn’t try to dig a navel stone out yourself, especially with tweezers or sharp tools. A doctor can remove it with forceps, sometimes after applying a liquid to soften the mass first. In rare cases where the stone is firmly lodged, a small incision in the surrounding skin makes removal easier.
Yeast Infections
The belly button is a prime spot for yeast overgrowth because it’s warm, dark, and often damp. The most recognizable sign is a bright red rash in the skin folds of the navel, usually intensely itchy and sometimes accompanied by a burning sensation. You might also notice white discharge, scaling, or swelling.
Over-the-counter antifungal creams are the standard first treatment. You apply the cream directly to the affected skin inside the navel. If that doesn’t clear things up within a week or two, a prescription-strength antifungal may be needed. Keeping the area clean and dry is the single best way to prevent yeast from returning.
Bacterial Infection
A bacterial infection of the navel (omphalitis) is less common in adults but does happen, particularly after piercings, surgery, or prolonged neglect. Signs include redness, warmth, tenderness, and swelling in and around the belly button. The area may feel hard, and you might see pus draining from it. If the infection spreads into deeper tissue and the opening swells shut, the whole navel can essentially become an abscess. Any combination of pus, increasing pain, and spreading redness warrants a visit to your doctor.
Cleaning a Navel Piercing
A new belly button piercing needs more careful attention than unpierced skin, and the cleaning solution is slightly different. The standard recommendation is a sea salt soak: dissolve 1/8 to 1/4 teaspoon of non-iodized sea salt in one cup of warm distilled or bottled water. Soak the piercing for about five minutes. You can do this by filling a small cup, pressing it gently against your abdomen, and leaning back, or by soaking a clean gauze pad and holding it against the piercing.
Avoid using rubbing alcohol, hydrogen peroxide, or harsh antibacterial soaps on a healing piercing. These can dry out the tissue and slow healing. Navel piercings typically take six months to a year to fully heal, and consistent gentle cleaning throughout that period reduces the risk of infection and irritation.
Cleaning After Surgery
If you’ve had laparoscopic surgery or an umbilical hernia repair, one of the incision sites is often right at or inside the belly button. Post-surgical care follows different rules than routine hygiene. The priorities are keeping the incision clean, dry, and protected while it heals.
Wash your hands before and after touching the area. Clean the incision gently with mild, unscented soap and water, then pat it dry with a clean cloth. Showers are preferred over baths because you want to avoid soaking the surgical site. Inspect the area daily for signs of infection: new swelling, pus, or color changes in the surrounding skin. Avoid tight waistbands that could rub against the incision, and hold off on activities that involve bending, twisting, or lifting until your surgeon clears you.
What Not to Use
You don’t need rubbing alcohol, hydrogen peroxide, or antibacterial wipes for routine belly button cleaning. These products strip away natural oils and can irritate the delicate skin inside the navel, leading to dryness, cracking, and paradoxically making infection more likely. Scented soaps and body washes can cause similar irritation. A plain, fragrance-free soap is genuinely all you need. If your belly button is healthy and you’re cleaning it regularly, there’s no reason to reach for anything stronger.
