We recommend removing all jewelry before sleeping, swimming, showering, mountain climbing etc. 

To clean, wash with warm soapy water. Gold jewelry can also be cleaned lightly using a soft cloth. For a more thorough cleaning, soak your gold jewelry in a glass of warm water with a drop or two of non-detergent soap to remove any oils and loosen buildup. Remove after a few minutes and pat dry with a soft cloth. To clean further, use a very soft, worn toothbrush to carefully remove any dirt particles or debris from more intricate components and settings. 

Sterling Silver jewelry can also be cleaned with a watery paste of baking powder and water or toothpaste to remove tarnish. Rub gently and rinse with water.
