What is a jewelry cleaner?
<|assistant|>
A jewelry cleaner is a product or device used to remove dirt, grease, dust, and other contaminants from gold and silver jewelry. They can come in the form of solutions, sprays, wipes, brushes, and foams. The most common types of cleaners are warm water solutions with mild detergents, baking-soda-based powders, and ultrasonic cleaners. 

The key to selecting the right jewelry cleaner is to find one that is safe for the type of metal used in the jewelry and that removes dirt and residue without damaging the surface of the jewelry. Regular use of cleaners can help keep jewelry bright and shiny.
