To preserve your badge's new look and shine, wash it occasionally with mild soap and warm water. Dry it with a clean, soft cloth.  

Smith & Warren badges do not tarnish.  If your badge appears to have lost its lustre, it is dirty (not tarnished).  You can clean it with mild soap and water, or use a mild, non-abrasive cleaner such as glass spray (windex). 

NEVER use jewelry polish, brass cleaner, toothpaste, or any other harsh abrasive or chemical cleaner.  These types of cleaners will damage the finish of your badge.
