Answer: Stay away from jewelry cleaners and antibacterial soaps which may have certain components that will just make your gold plated grillz tarnish more quickly. To avoid scratches, wrap your grillz in a soft cloth after cleaning and/or keep it in the included storage box separate from other types of jewelry you have. Grills, also called “grillz” or “fronts,” are decorative covers often made of gold, silver or jewel-encrusted precious metals that snap over one or more of their teeth. They generally are removable but some grill wearers have had their teeth altered with gold crowns to permanently resemble a grill.
