Yes you can use apple cider vinegar to make natural ear drops for clearing out earwax and for even treating ear infections.
Take some apple cider vinegar and mix it with some warm water and then use an ear dropper to apply a few drops of the apple cider vinegar to your ear and let it sit to clear the earwax.
If you're treating an ear infection with the apple cider vinegar just apply the apple cider vinegar ear drops to your ears like you would any other ear drops and let it sit in your ear for awhile.
Then clean your ear out after 15 to 20 minutes.
