I believe the best way to prevent swimmers ear is to use a homemade swimmer’s ear prevention solution. You make this by mixing isopropyl alcohol with a small amount of white vinegar in one of the over the counter droppers you can buy at the chemist. Then after each time you or your child gets out of the water you use a few drops to dry out the ear and prevent bacteria from growing. It works because the isopropyl alcohol displaces and water then evaporates quickly leaving the inner ear dry, and the small amount of vinegar lowers the pH of the solution which makes it difficult for any bacteria to survive.
