Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
The irrigation solution flows out of the canal along its floor, taking wax and debris with it. The solution used to irrigate the ear canal is usually warm water, [37] normal saline, [38] sodium bicarbonate solution, [39] or a solution of water and vinegar to help prevent secondary infection. [37]
Saline solution normally contains 0.9% sodium chloride. This article walks you through application instructions based on the intended use.
The types of intravenous fluids used in fluid replacement are generally within the class of volume expanders. Physiologic saline solution, or 0.9% sodium chloride solution, is often used because it is isotonic, and therefore will not cause potentially dangerous fluid shifts. Also, if it is anticipated that blood will be given, normal saline is ...

[3] [4] Generally, the use of a cerumenolytic involves instilling several drops of the product into the affected ear once or twice daily for a treatment duration of 3 to 5 days. [ 1 ] [ 4 ] Each instillation is relatively quick (less than 5 minutes) and can be done either at home or in a clinical setting.
The water should not be tap water, which may contain small amounts of bacteria that are safe to drink but may be dangerous in the nose. The water should be sterile or filtered for micro-organisms; if tap water is used it should be boiled and cooled. [4] Saline solution is also sometimes used. [2]
