How do I clean my jewelry?

In the rush of packing up on move out day at the end of the spring semester, I stupidly put my swiffer mop wipes package upside down and on top on my jewelry organizer 🤦🏼‍♀️

I can’t even wear the necklaces without it hurting my skin. How do I clean these pieces without ruining them? Most of it is stainless steel and I have a few pieces of costume jewelry. But I do have actual silver pieces as well as some pearls.
