Even if you have tarnished silver things, like silver(-plated) cutlery etc. the "un-tarnishing" is stupid easy and cheap to do:
- take some container and put warm/hot water and a large helping of (table) salt into it
- put some scrunched up Al foil into the water
- submerge the objects to be untarnished in the water so that the silver touches the Al foil
- leave for a while in a well ventilated area (since it will smell of rotten eggs)
- rinse well
- done.
recipe from a kid's chemistry set I had a looooong while ago, used it successfully quite a few times on my parents' silver-plated cutlery they've had and used regularly since their wedding decades ago.
