Silver cutlery becomes dark after some time and sometimes even black. Since this does not look very nice, there are several ways to clean it. In contrast to the use of "silver cleaning cloths", the variant described here is less labor-intensive, but you must pay attention: Wear protective goggles, as soda is alkaline! Please do not use scouring powder or soda, as this will cause scratches or hydrogen sulfide formation!
