Why does my piercing smell? The cause, and how to fix it without over-cleaning

The smell has a name in piercing circles, and it is not a polite one. It is also almost never a problem. Skin sheds oil and dead cells constantly, a piercing channel is a place where both collect, and bacteria break them down into something that smells like a belly button. That is the whole explanation for most cases.

What matters is telling that ordinary build-up apart from the smell of an infection, and then cleaning it without doing the thing that causes more trouble than smell ever does, which is over-cleaning.

Where the smell comes from

Your skin produces sebum, an oil, and sheds dead cells all day. In a piercing channel those two things have nowhere to go: they sit against the jewelry, mix with sweat, and the bacteria that live on everyone’s skin digest them. The by-product is the smell.

Three things make it stronger:

• Surface area. A stretched lobe has far more channel than a nostril, which is why stretched ears are the most common complaint.
• Porous jewelry. Acrylic, silicone, wood and bone absorb oil and hold the smell. Glass, implant-grade titanium and steel do not.
• Jewelry with hiding places. A butterfly clasp, an externally threaded post, a hollow bead: all of them trap debris that a smooth flat-back stud does not.

A healed piercing with a faint smell after a few days without cleaning is behaving normally.

Smell versus infection

The smell alone is not a symptom. Infection is a cluster of things, and smell is a minor member of it.

Smell with none of the right-hand column is build-up. Smell with any of it is a doctor’s visit, and the infected ear piercing guide has the same-day signs.

Cleaning a healed piercing

For a piercing that finished healing months or years ago:

1. In the shower, let warm water run over it, and use a small amount of mild, fragrance-free soap on the skin around the piercing. Rinse thoroughly. Soap left in the channel irritates.
2. Clean the jewelry separately. Take it out, wash it with warm water and the same soap, dry it, and put it back. For a flat-back stud that means removing the end; the post can be wiped in place.
3. Dry the area with clean paper towel rather than a used cloth towel.
4. Do this every few days, or daily for stretched lobes.

Do not rotate the jewelry through the channel to “clean inside it.” On a healed piercing it does nothing useful, and on a healing one it does damage.

Cleaning a healing piercing

A piercing that is still healing produces lymph, a clear fluid that dries into a whitish crust on the jewelry and can smell slightly on its own. That is normal.

The routine does not change because of the smell: sterile saline twice a day, patted dry, nothing else. Soap, alcohol, peroxide and extra cleaning sessions all irritate healing tissue, and irritated tissue produces more discharge, not less. The aftercare guide and the ear cleaning guide cover the routine, and why is my piercing itchy covers the other sensation that worries people for no reason.

Change the jewelry, not the routine

If a healed piercing smells persistently despite regular cleaning, the jewelry is usually why.

• Acrylic, silicone, wood, bone or horn absorb oil. Switch to glass or implant-grade titanium, which are non-porous and can be washed properly.
• Butterfly-back studs trap debris in the clasp. Switch to a flat-back stud, which has a smooth disc and nowhere to hide anything.
• Externally threaded posts have a screw thread that fills with debris. Threadless or internally threaded jewelry is smooth along its length. See the materials guide.
• Hollow or ornate beads collect grime. Solid ends are easier to keep clean.

Stretched lobes

The worst offenders, for reasons of surface area. The routine is daily: wash the lobe front and back in the shower, remove and wash the plugs, dry both, and replace. A drop of unscented jojoba oil on the lobe afterwards helps some people; anything scented does not.

Glass, steel and titanium plugs stay cleaner than organics. If you love wood or stone, accept that it needs washing every day and drying fully before it goes back in.

When to see someone

A piercer if a healed piercing smells despite the above and you suspect the jewelry or a build-up you cannot reach.

A doctor, the same day, if the smell comes with heat, spreading redness, thick coloured discharge or fever. That is infection, and smell was never the important symptom.
