For stainless steel and other alternative metal jewelry (such as titanium, tungsten and cobalt), the cleaning process is quite simple. If it has a colored coating or enamel on it, you can use a soft dampened (with slightly soapy water) microfiber cloth, followed by a cloth with clean water to remove soapy residue, followed by a dry one to remove moisture. If it does not have a coating or enamel, you can use the softest brush you can find (think a toddler’s or infant’s toothbrush softness) to remove any grime or dirt, rinse with clear warm to cool water then dry with a soft cloth. We do not recommend using sponges or regular-to-firm bristled brushes. Even though these metals are very hard, they can be easily prone to scratching.
