Vinegar
Many kinds of vinegar, especially apple cider vinegar, contain acetic acid. This substance is able to kill the fungi that trigger an infection in your nails. All you need to do is to mix white vinegar with warm water and soak your nails in this solution for around 15 to 20 minutes before rinsing with clean water. Make sure to do it once per day in a few weeks to ensure the best results. [3]
