According to this article in Popular Science magazine. You can take all your household metallic items and dip them in Muriatic acid to reveal neat crystalline patterns. Problem is muriatic fumes stain just about anything and the smell is worse than a bottle of sudsy ammonia on the other hand you can process your gold scrap with it and it's also good for getting rid of pesky yellowjackets, enjoy.
