Hi sol, well one reason why peroxide would not clean tarnish off is that. On pure silver the tarnish might be silver oxide, so adding more oxygen from peroxide would not do anything. you want to add something that combines with the oxygen in the silver to remove it. Like the vinegar which is an acid and a proton donor.
when you are dealing with sterling silver however it is a different story because most of the tarnish on sterling silver comes from the copper oxidizing. silver polish usually contains soem thing that will remove that esily. In both case it is due to oxides on the metal and sometimes also sulfurs on the metal. peroxide provides more oxygen so would not work well to remove metal oxides. You need something that combines with oxygen to remove the oxides not provide more oxygen for making oxides. peroxide works good for bleaching colors because it oxidzes certain substances that are colored. It might be more involved than this in some details but that is basically it.
