What household products can I use to polish silver?

i've heard you can use toothpaste. though i've never tried it.

I've actually used toothpaste and it works initially, but the oxidation will come back.

Oh. Try this: Line the bottom of the pan with aluminum foil or use a disposable aluminum pan. Place silver object on top of the aluminum, making sure the silver touches the aluminum. Pour boiling water into the pan until the object is completely covered. Add about baking soda. (about 1/4 cup per liter or 1 cup per gallon of water).

Wright's Silver Cream is the best silver polish out there! It is CHEAP and in the grocery store! My mother used it for years and years...I use it and now my kids use it. I would love to pass this 'tip' along to my nieces and nephews as well!! :))

from Martha Stewart's Good Things (Homekeeping area) "Removing Tarnish A simple chemical reaction causes tarnish to disappear naturally. Place sterling or plated silver in an aluminum pan%u2014it must be aluminum. Sprinkle 1/2 to 1 cup baking soda over the silverware. Keeping the pan in the sink to minimize splashing, pour enough boiling water to cover the utensils. When the tarnish disappears, remove the silverware, and buff with a soft cotton cloth. "

White toothpaste is great, and it works for all types of jewelry as well
