Swimmer’s ear (otitis externa) is an outer ear infection that’s commonly caused by water that stays in your ear after swimming or other water-related activities.

Water that remains in your outer ear canal, which extends from the outside of your ear to your eardrum, creates a moist environment that promotes the growth of bacteria.

According to the Mayo Clinic, swimmer’s ear can also be caused by damaging the thin skin in your ear canal by putting cotton swabs, fingers, or other objects in your ear.

Symptoms of swimmer’s ear can include:

Over-the-counter treatment

In many cases, swimmer’s ear is treated with over-the-counter (OTC) drops that are typically made up of isopropyl alcohol and glycerin. These drops work to help your ear dry out faster, not fight the infection. Be sure to follow the use instructions on the label.

Home remedies

If you don’t have a punctured eardrum, you can make your own homemade ear drops to use before and after swimming. This solution can help dry out your ears and discourage the growth of bacteria.

To make this solution, do the following:

  1. Mix equal parts rubbing alcohol and white vinegar.
  2. Place approximately 1 teaspoon (5 milliliters) of the solution into one ear and let it drain back out. Repeat for the other ear.

Medical treatment

A doctor will most likely prescribe ear drops that combine an antibiotic or acetic acid to kill bacteria. To calm inflammation, they may also prescribe a corticosteroid.

If a doctor diagnoses the cause as a fungal infection rather than a bacterial infection, they may also prescribe ear drops with an antifungal.

An ear infection is a reason for a doctor’s visit. According to the Mayo Clinic, ear infection symptoms may include:

Although most ear infections clear up on their own in a couple of weeks, some practitioners of natural healing suggest treating an outer ear infection with a mixture of equal parts rubbing alcohol and apple cider vinegar (ACV).

This home remedy is based on the antimicrobial (kills microorganisms) and antibacterial (kills bacteria) properties of rubbing alcohol and ACV.


If you have any symptoms of an ear infection, see a doctor for a full diagnosis before putting anything, including rubbing alcohol or apple cider vinegar, in your ear.
