4 oz. zinc oxide powder
4 oz. boric acid powder
1/2 oz. Iodoform powder
Mix well. Keep in a sealed jar in a cool dry place.
Place a large pinch of powder in each ear, and use your finger to work it down. Wait five or ten minutes (I cut toenails) then pluck the hair out of the ears, being sure to get all the way down. Allow the dog to shake, but leave the excess powder in the ears. Repeat monthly.

Treatment of an existing infection:
Use as described for maintenance, then apply a fresh pinch of powder to each ear. Wait twenty-four hours, then use a dry q-tip to remove all the powder and the balls of dried gunk. Put a fresh pinch of powder in each ear. Repeat daily until the ears are no longer runny. At this point, repeat every other day, until there is no more runnyness, then three times a week, then twice, then weekly, then every other week, etc. When the ears remain dry for three weeks, go to the monthly maintenance routine.
The reason this works so well is that the iodoform powder kills anaerobic bacteria and fungi which flourish in warm, moist, airless places, like the inside of a poodle's ear. The zinc oxide and boric acid keep the ear dry, which prevents further infections. In the days before antibiotics, iodoform was frequently used in human medicine to pack puncture wounds where anaerobic bacteria also grow. It may be hard to find because it isn't used much any more.
