First, the salt acts as a natural antibacterial agent, which can reduce the presence of bacteria and help to prevent further infection. The warmth of the solution can also soothe inflamed tissues, providing comfort and potentially reducing pain associated with the condition.

Drying the ear afterward is crucial because it prevents moisture retention, which is a key factor in the development and worsening of otitis externa. Keeping the ear canal dry helps to break the cycle of irritation and infection, facilitating healing. This approach is often recommended for mild cases where the infection has not become severe.
