Metal steps bars, nerf bars and running boards can become unsafe when wet. Even though some types of steps come with either a tread strip or may be designed to minimize the accidental slip, some do not perform as intended. Generally, these steps and running boards very easy to clean, but can become very slick, too, especially if they do have the tread strip. Never use a wax or polish on any plastic surface, this will give a chalky and dry look to the plastic and is very hard to remove.
