Impregnate your Uggs regularly so they withstand moisture better and you reduce the risk of stains. Avoid getting in the snow with your suede eyes and keep in mind that road salt can give dull salt streaks. If you get a salt stripe, do this: first rub gently on the stain with a suede brush / stone. Soak the entire shoe with a damp sponge and clean with shoe shampoo intended for suede. Fill the shoe with newspaper and let it air dry. Do not place the shoe near a heat source such as an element or fireplace.
