Where there is cooking there is usualy cleaning, RIGHT? These days that often means a automatic diswasher.
Keep items of different metals separated in the silverware basket of the dishwasher. Knives, forks spoons or whatever cutlery and other metallic objects can become discolored or pitted if dissimilar metals (stainless steel, silver, etc.) are touching when washed. The water-soap solution can allow electrolysis to occur that blackens or pits the surface of the metal utensils.
Not a problem for obects of the same material but silver plate against a carbon steel butcher knife or stainless spoon could cause a problem.
Want to test the electrolysis effect? take a couple utensils made of different metals like silver and steel or whatever, touch them to each other and then stick your tongue so that it touches both metal objects (careful with sharp knives and such!) and you will detect an acid or odd taste. This is the electric current being generated by the battery formed by the different metals in contact with the electrolyte (your saliva) that flows through the closed circuit provided by your conductive tongue. As kids, we used to "taste" a copper penny touching a silver dime or aq nickel ... moms of the world really hate that... oooooooh putting dirty money in your mouth!
Folks with "silver" fillings sometimes can get this "odd" taste when they put something metallic in their mouth. It is due to the battery formed between the fillings and the other "different" metal. Actual silver, silverware, doesn't do this unless your fillings are a different metal, say stainless steel if you went to a Soviet dentist, komrad.
