For an at-home pedicure treatment, Brenner advises soaking your feet for 10 to 15 minutes two to three times a week in an Epsom salt solution, made of two cups of Epsom salt per gallon of tepid water.

At that point, you've done most of the leg work, so to speak, and you can leave the polish to the professionals.
Warning signs. Infections from the nail salon can often look like bug bites, which worsen and enlarge and can cause pus and scarring, according to the EPA and CDC. Yellowed nails or scaling skin around the base of the foot indicate fungal infections, while anything "red and angry looking" is likely a bacterial infection, Brenner says. Determining the existence of hepatitis requires a blood test.
