Key Takeaway: Rubbing alcohol in ear canals can help dry out water after swimming, usually mixed half and half with white vinegar. It does not dissolve earwax or treat an infection. Skip it if you have ear tubes, a punctured eardrum, ear pain or drainage. Ask your provider first, and see an ear, nose and throat doctor (ENT) for real symptoms.

You climb out of the pool, tilt your head, hop on one foot, and the water still sloshes. Someone at the swim club swears by a capful of rubbing alcohol. Another person says never put rubbing alcohol in ear canals, ever. Both are partly right. We sell hearing aids, not home remedies, so we have nothing riding on your answer, and the honest version comes down to one question: what is the alcohol supposed to do?

What Rubbing Alcohol Does Inside the Ear Canal

Rubbing alcohol is a drying agent. That is the one job it does well in an ear, and it explains both when it helps and when it hurts.

Water trapped in the ear canal after swimming or a shower softens the thin skin there and keeps it warm and damp. Bacteria and fungi thrive in exactly those conditions. That is how swimmer's ear starts, an infection of the skin lining the outer ear canal. Alcohol mixes with the trapped water and then evaporates far faster than water does on its own. As it evaporates, it carries the water out with it.

White vinegar adds a second effect. A healthy ear canal is slightly acidic, and that acidity discourages germs. Vinegar nudges the canal back toward that acidic state after a swim. That is why the classic home mix pairs the two.

The same drying power is the problem when the skin is already damaged. Alcohol on irritated or broken canal skin stings, and it strips the moisture the skin needs to heal. If the eardrum has a hole in it, the liquid has an open path into the middle ear, which is not built to have anything poured into it.

When Rubbing Alcohol in the Ear Can Help

The case for alcohol is narrow: preventing swimmer's ear in a healthy ear that gets wet often. Mayo Clinic describes a mix of one part white vinegar to one part rubbing alcohol, used before and after swimming. Mayo's version calls for about a teaspoon in each ear, then letting it drain back out. It adds that the mix is only for ears without a punctured eardrum, and that similar over-the-counter drops might be available at your drugstore.

The CDC's swimmer's ear guidance recommends asking your healthcare provider before using any ear-drying drops. It also lists drying methods that need no liquid at all:

• Tilt and tug. Turn each ear toward the floor and pull the earlobe in different directions so water can run out.

• Towel dry. Dry the outer ear well after swimming or showering.

• Use a hair dryer on low. Set it to the lowest heat and fan setting and hold it several inches from the ear.

• Keep water out before it gets in. A swim cap, earplugs or custom swim molds block most of it.

For many people, those steps are enough, and you need no drops at all.

When to Keep Rubbing Alcohol Out of Your Ear

The CDC is direct on this point. Do not use ear-drying drops if you have any of the following:

• Ear tubes, the small tubes placed in the eardrum to drain the middle ear

• A punctured or ruptured eardrum, or a history of one you are not sure has healed

• Swimmer's ear already underway, meaning pain, swelling or itch that keeps building

• Drainage of any kind from the ear

Each of those means the canal or eardrum is already open or inflamed. Pouring a drying, stinging liquid into it can hurt and can make a bad situation worse. If you have recently had a ruptured eardrum, our post on which side to sleep on with a ruptured eardrum covers how to protect it while it heals.

 

What Rubbing Alcohol Will Not Do

Most people who grab the bottle want one of five things from it. Only one of them is a job alcohol does.

The earwax row matters most. According to the CDC, you should not try to remove earwax at all, because it protects the canal from infection. Our guide to why your ears itch deep inside at night explains how cleaning inside the canal keeps irritation going.

Signs You Need an ENT, Not a Home Remedy

Swimmer's ear can move quickly from a mild itch to a painful infection. Mayo Clinic lists the early signs as itching in the canal, mild redness, discomfort that gets worse when you pull the outer ear, and some clear fluid draining out.

See an ear, nose and throat doctor (an ENT) or your primary care provider if you notice:

• Pain that is increasing, especially when you touch or tug the outer ear

• Fluid or pus draining from the ear

• A feeling of fullness or muffled hearing

• Itching that keeps getting more intense

• Fever along with ear pain

Mayo Clinic notes that hearing can drop temporarily while swimmer's ear runs its course, and should return once the infection clears. If muffled hearing hangs on after the infection has cleared, see an ENT. Our post on a clogged ear from a sinus infection covers another common reason an ear stays plugged.

Your Questions About Rubbing Alcohol in the Ear, Answered

Can rubbing alcohol in your ear cause hearing loss?

In a healthy ear with an intact eardrum, a few drying drops are unlikely to affect hearing. The risk comes with a punctured eardrum or ear tubes, which is why the CDC says not to use drying drops in those cases.

Is hydrogen peroxide better than rubbing alcohol for ears?

They do different jobs. Alcohol is a drying agent. Ask your provider before putting peroxide or any other liquid in your ear, and never use either one with a punctured eardrum or ear tubes.

Can I clean my hearing aids with rubbing alcohol?

Check the cleaning instructions from your hearing aid's manufacturer before using any liquid on the device. Take your hearing aids out before you put any drops in your ears. Our hearing aid maintenance guide covers how to clean and care for your hearing aids.
