For topical application only. General cleansing: Use generously to remove dirt, grit, coagulum etc. The residual solution will promote sloughing of de-vitalised tissues. Otitis Externa: Use liberally to clean the ear canal. When wax is hard the solution may be left in-situ to soften the wax, allowing easy removal next day. This process can be repeated 2-3 times daily if necessary.
