I have what I am pretty sure are warts (I have had them many times before) that I am putting apple cider vinegar (ACV) on for the past 5 hours, so far they have not turned white but do look like they might be swelling a little. I have read on many sites that ACV will help remove the warts. Most recommend keeping it on while sleeping every night for a week, but there have been a few people who claim they soak a cotton ball in ACV and keep it taped with a band aid to the effective area for 24 hours, removing only to bathe, then cleaning the area with hydro peroxide and then reapplying a new soaked cotton ball. This is what I am trying because many have claimed that it cleared up the warts within a few days. From my understanding the warts will swell (stage I am at now), then dry out and scab off. Once I reach the dry stage I will soak in the bath and rub them gently with a wash cloth in hopes to speed up the process. Last time I had warts my doctor gave me an RX for Aldara and that did work, it took about a week and a half and caused the warts to become smoother and smoother until they were flat and then nothing but a reddish spot and then gone. Aldara is a cream that you put on daily, a lot of people don't like it but I had no problem with it =)
