How does acetic acid work?
Acetic acid lowers the pH in the outer ear canal, creating conditions that inhibit susceptible bacteria and some fungi. It acts locally.
How to take acetic acid
Use only in the external ear canal. Shake the bottle and prime the pump before first use until a fine spray appears. Gently position the nozzle at the ear opening and operate it as directed. Do not inhale the spray or use it near the eyes. Re-prime after a prolonged gap and use the bottle within one month of first use.
Keep the container upright in its carton.
