I use Weimans silver polish. Never ever use Tarnex, it will cloud up and ruin your silver. Some people use white toothpaste.
Marian, here are a few good ways to get silver-plate clean and shiny.
HI Marian - This is the most effective and all-natural silver cleaning and polishing method that we use. It's also been featured by Hometalk. Hope this helps! Hugs, Holly
PS - I'm getting ready to release a FREE eBook with recipes for all of my homemade and all-natural cleaners. If you want to know when it's released, you can get it here --> https://pinkfortitude.com/thank/
Silver polish or garnet works well
