Homemade Swimmers ear drops !!! I even use this for my dogs Materials: Vinegar Everclear or vodka ethyl alcohol or 70% rubbing alcohol eye drop container or anything with the ability to distribute drops Directions: 1. Fill container you have selected with equal parts vinegar and alcohol. Mix thoroughly. 2. Put 4 drops in each ear after swimming. The alcohol dries out the ear and the vinegar kills bacteria.
