A cotton bud dipped in Povidone Ointment and then lightly dipped in Boric Acid powder. Gently place cotton bud just a very small way into the ear and then remove the cotton bud from ear. Gently massage back of ear. 2 or 3 applications a day. The Povidone ointment/Iodine clears infection and the Boric acid powder dries water.
