Dry silver is best - chemicals and contaminants in swimming pools and hot tubs can tarnish or dull your cuff.  Simply dry off your cuff after exposure to this type of water.  

Polish to return to luster - silver is delicate, and despite our best efforts, it can still get dirty. Sterling silver care is easy.  Use a typical microfiber cloth in long up-and-down strokes to clean your cuff.
