Buy some Dial antibacterial bar soap and a good, new, nail brush. Soak the foot in warm water for one minute. Then scrub gently with the Dial soap and the brush for 3 minutes.

Keep a sock on the foot at all times, so you don't get any dirt in there.

Do this AT LEAST 3 times per day, 4 if you can work it into your schedule.

10 days to 2 weeks "should" do it, although I don't know how deep your warts have gotten.

Once the wart is GONE, keep doing this for 3 more days.

This worked for me when I had one, on the bottom of the foot, about 35 years ago.

Dad's foot doctor is also a foot surgeon and he is strongly angainst the use of those freeze and acid over the counter methods.
