Ear Wax Removal: Current Solutions & Problems WASH-ONLY SOLUTIONS Ear Irrigation performed by physicians with water and syringe is time consuming, associated with as much as 38% complications (such as eardrum perforation or canal laceration). Ear Irrigation performed by physicians with water and syringe is time consuming, associated with as much as 38% complications (such as eardrum perforation or canal laceration). DISSOLVE-ONLY SOLUTIONS Cerumenolytic preparations Ear drop application, requires head tilting for 5-10 minutes, is uncomfortable, with occasional leak out of the ear, bad odor, soiling of bed sheets or cloths.

CleanEars Ingredients & Mechanism of Action CleanEars is based on physical - mechanical logic. CleanEars is based on physical - mechanical logic. The active ingredient is natural squalan extracted from olive oil. The active ingredient is natural squalan extracted from olive oil. Squalan has similar composition, structure and character as of ear wax but is in liquid form. Squalan has similar composition, structure and character as of ear wax but is in liquid form. When applied into the ear canal as a spray, squalan particles slam into the slow moving wax particles. As in any collision, some of the kinetic energy is transferred to the wax solid particles, enabling their transformation into liquid wax material.
