Question: how many times a day can you soak in apple cider vinegar?
Answer: “Since apple cider vinegar is acidic, it works to create an unfriendly environment for the fungus without being so strong as to damage the surrounding area of skin and nails,” he explains. To do, soak the affected toe in a 50:50 mix of ACV and warm water for 15 to 30 minutes, twice daily.
