Earrings smell because skin oils, sweat, dead skin cells, and bacteria build up on them. Clean them with soap or rubbing alcohol.
Why
Skin oils, sweat, dead skin cells and bacteria build up on earring posts. This makes a smell.
Other causes
Piercing infection, ear discharge or earwax.
Cleaning
Wash with warm water and soap. Wipe with alcohol or saline.
Prevention
Remove earrings at night and use hypoallergenic metals (surgical steel, titanium, gold).
See a doctor
If the ear is red, swollen or has pus.
Sources of the smell
The odor from earrings is usually due to a mix of sebum, sweat, dead skin cells and bacteria trapped in the piercing channel or on the post. Sulfur-like or cheesy smell comes from bacterial breakdown of skin oils. New piercings have a longer risk, since healing earlobe takes 6 to 8 weeks and cartilage takes 4 to 12 months.
- Nickel in cheap earrings can cause contact dermatitis in about 10 to 15 percent of people, with itching, redness and discharge.
- Sleeping in earrings and not cleaning them lets residue build up.
- Hypoallergenic materials include implant-grade titanium, surgical stainless steel 316L, niobium and 14k gold or higher.
Cleaning
Wipe posts with rubbing alcohol or soap and water. Clean new piercings with sterile saline twice daily. Do not use hydrogen peroxide, which can damage healing tissue. Seek care for pus, spreading redness, heat or fever. Cartilage infections can cause lasting deformity, called cauliflower ear, so they need medical attention promptly.
Source of the smell
Pierced earrings can smell from sweat, dead skin cells, sebum, products and bacteria that build up on the post and in the piercing channel. Bacteria like Staphylococcus and Cutibacterium break these down into smelly compounds. Metals such as nickel can irritate skin in people with allergy, which affects roughly 10 to 15 percent of the population.
Cleaning
Wash earrings with mild soap and water, then wipe with 70 percent isopropyl alcohol and dry. Choose hypoallergenic metals such as surgical stainless steel, titanium, 14k gold or niobium. Clean the piercing with sterile saline and see a clinician if there is pus, redness, swelling or warmth, as these signal infection.
Why jewelry gets smelly
Skin sheds cells and produces sebum and sweat continuously, and a piercing channel (fistula) collects them. Bacteria such as Staphylococcus epidermidis and Corynebacterium break the material down, forming a cheesy smell. Wearing the same earrings for weeks, sleeping in them and using low quality plated metals worsens it.
Cleaning routine
Remove earrings, wash with warm soapy water, soak briefly in saline or wipe with 70 percent isopropyl alcohol, and dry. Clean the earlobe with sterile saline or mild soap. For new piercings, follow the piercer’s aftercare for 6 to 8 weeks for lobes. Replace worn posts and avoid sleeping in hoops. A healthy lobe does not have discharge or lasting odor.
