I applied pure "food grade" turpentine to the insides of both ears with cotton swabs and it was very painful, it felt like an ear infection. After a while the pain went away. And maybe a day or so later a white skin of sorts came out of each ear. It looked like dry skin, so it was probably the ear canal shedding the top layer because of the strength of the oil. It did not appreciably affect the itchiness. Alcohol is said to cure athlete's foot, so it may cure the ear problem.
