Homemade Swimmers’ ear drops !!! I even use this for my dogs

Mix equal parts of white vinegar and rubbing alcohol in a small, clean dropper bottle.
Before use, make sure to shake the bottle well.
For humans: Tilt your head and place 3-4 drops into the affected ear, then let it sit for about 30 seconds before tilting your head to allow the drops to drain.
For dogs: Gently place a few drops into the dog’s ear, then massage the base of the ear to allow the solution to clean the ear canal.
This combination works because vinegar helps restore the ear’s natural acidic environment, while rubbing alcohol helps dry out any moisture trapped in the ear.

However, always make sure that there’s no eardrum damage before using these drops. If there’s any pain, discharge, or uncertainty, consult a veterinarian or doctor before using these drops.
