Homemade Swimmers ear drops...From the original pinner: "Recipe provided to me by my childrens' pediatrician. Alcohol dries out the ear and vinegar kills bacteria. It works!" it really does work! i had cronic ear infections and used these drops for YEARS as a kid on advice of the family doctor. would prevent ear infections when used after a shower, and if i forgot to use them and i started to get one it would stop it before it could get a real start.
