There are many people who believe that vinegar is an effective home remedy for treating toenail fungus. But this requires soaking the feet for 20 minutes a day for 3 – 6 months to be effective. Many people find this to be inconvenient and very difficult to maintain. Even TV’s famous Dr. Oz has recommended the use of a combination of vinegar and a mouthwash (containing thymol) for improving the appearance of toenails due to fungus. Both vinegar and thymol are ingredients in Piggy Paste.
