It is recommended to clean the RHINOSHIELD 2-in-1 Ultra Lanyard with water or a mild, neutral detergent. After cleaning, let it air dry in a well-ventilated, shaded area. Since the product contains metal components, avoid using washing machines, strong chemical cleaners, or alcohol for cleaning. If alcohol disinfection is necessary, we recommend using 75% alcohol for a quick wipe of the lanyard surface.
