Bananas provide several health and household benefits including whitening teeth by rubbing the inside of the peel on teeth for 2 weeks, soothing skin irritations by applying the peel to affected areas due to its acids and minerals, and improving complexion by massaging the peel on the face a few times a week to exfoliate and nourish skin. Banana peels can also shine leather shoes and polish silverware by rubbing the inside of the peel on surfaces, and speed the ripening of other fruits by placing banana peels in a sealed bag with the fruits.
