Wax is a system working. Glands in the outer third make it; the canal skin rides a slow conveyor outward and sheds at the opening, carrying trapped dust and wax along. The wax is acidic, around pH 4 to 5, and its fatty fraction kills common skin and respiratory bacteria 1. The smear on your pillow is the export line delivering.
A cotton swab does the opposite of clean. The shaft fits the outer canal perfectly, so it pushes wax past the narrow point and packs it against the gland-free zone near the eardrum, where the conveyor can't reach. Each session compacts it harder. The "my ears make too much wax" plug is usually years of swab-driven compaction, plus scratches that let in infection. Cotton-tip applicators send about 12,500 U.S. children a year to the emergency room 2.
The whole adult routine is a wipe of the outer ear. Nothing narrower than your elbow goes inside. The rest is knowing when to hand it to a clinician.
The product barely matters: mineral oil, olive oil, and peroxide drops perform about the same 3. Buy the cheapest.
Three groups have real work beyond "leave it alone." Hearing-aid wearers: the mould presses wax inward, and a blocked receiver is the top reason an aid goes silent, so get a six-month check. Swimmers: the problem is a wet canal, so dry it with a few drops of half isopropyl alcohol, half vinegar after water. Over-60s: wax turns drier and migrates worse, so "her hearing is going" is often a five-minute fix 4.
Leaving healthy ears alone pays off invisibly: within months you stop thinking about your ears at all. The loud payoff belongs to two groups. People stuck in the itch-scratch cycle find it quiets within a few weeks, as the skin re-greases and the infections stop recurring. People with an established plug get a step-change from one appointment: the standard report after removal is that the world had been turned down and someone turned it back up.
The fine print — when to skip it, and what people get wrong
No home drops or rinsing if you have or ever had a perforated eardrum, any ear surgery or tubes, hearing in only one ear, or uncontrolled diabetes or a weakened immune system 4. See a clinician instead.
Wax at the ear opening is where it belongs; wet versus dry is set by one gene, not by washing 5. Ear candles create no suction; the FDA logs burns and perforations 6 7.

Earwax
Ear doctors have agreed on the same advice for forty years, backed by a major clinical guideline and emergency-room data on what cotton swabs actually do.
Stop cleaning your ears and you avoid most ear injuries doctors see — perforated eardrums, infections, packed wax. If your hearing suddenly drops, a clinic can clear it in five minutes.
