Put the tin foil wrapped in silver ornaments into a bowl, and then pour hot water into the bowl (slowly pour it around the tin foil, not all at once into the tin paper bag).
After soaking for 30 minutes, open the foil paper, take out your silver ornaments, wash off the excess salt, and dry until it shines.
Because the salt melts, it also takes away the dirt on the silver ornaments and will not scratch the surface.
