Got the ear fungus when I was on a family vacation when I was 9. Ever since when I bathe I have to swab out the ears with H202 or ethyl rubbing alcohol or I will get an earache. Sometimes used the olive oil also. I am 66 now and have used Qtip every day since age 9. Olive oil is the ONLY kind of oil to place in your ears. I never put Isopropyl in my ears. I do keep 91% Isop. around to clean electronics. Sometimes I buy everclear and dilute it to use that as 'rubbing alcohol to avoid denaturants.
