A very aggressive way to treat the feet is to soak them in warm water for 15 minutes. This will soften the dead skin on the surface, which can be scraped off with a loofah. Now the skin is ready and open for the gel to be applied to the entire foot. There are some sea salt scrubs that seem to help scrape the dead skin off with much more aggression. Silver kills the bacteria that causes odor and can be used to deodorize armpits, feet, breath and has been used for hunters to neutralize their odor while hunting.
