So next time you have a banana, don't toss the peel.
Cut off both hard ends and toss them out, then stick the peels in the blender. Puree it and then using a soft cloth rub your silver with it. Rinse the mush off and then buff your silver to a shine.
For spots of tarnish you can just use the inside of the peel.
