Tarnish does occur since surface elements of the silver react with sulphur from the air, or certain foods including eggs, to make a compound called silver sulphide. When you polish it off, you're actually removing several of the magic. For silver plated products, this means that with repeated polishing over a long time there is a threat of carrying com-pletely through the plating and exposing the bottom metal. The sole solution then would be to have them re-plated. Therefore an improved idea is to remove the tarnish by changing the silver sulphide back in silver.

The electric current causes a chemical reaction between the aluminium and the sulphur than gold has because aluminium has a higher affinity with sulphur. The sulphur in the tarnish is drawn to the solution and towards the aluminium, making the silver behind, where it belongs. The reaction occurs faster once the solution is warm.
