The biggest benefit of washing the ears is to clean out the secretions in the ear canal, but if the secretions in the ear canal are relatively small or minor, there is usually no need to deal with them because they will be discharged on their own through swallowing and chewing. If the water temperature is too low during rinsing, it may lead to transient vertigo, so it is also not recommended to do ear canal rinsing frequently. If the cerumen in the ear canal is too large, the ear canal rinse alone may not clean the cerumen in the ear canal. It is necessary to use sodium bicarbonate drops in the ear canal to soften the large cerumen and then do the rinse to clean the ear canal secretions. It is not recommended to clean the ear canal often because water in the ear may cause eczema in the ear canal. It is recommended not to go to private non-medical places for ear canal rinsing and it is better to get a doctor to do this treatment. It is recommended that you do not go to a private, non-medical facility to have your ear canal flushed, because if you flush at a non-medical facility, it may not clean your ear or may cause damage to the ear canal.
