Remove baked-on crud from pots and pans. Combine hydrogen peroxide with enough baking soda to make a paste, then rub onto the dirty pan and let it sit for a while. Come back later with a scrubby sponge and some warm water, and the baked-on stains will lift right off.
De-tarnish ALL your silver ALL at once... line your sink with aluminum foil, add 1/2 c table salt, 1/2 c. baking soda, fill with hot water, then dump in all your silver! Let sit for about 30 min. The tarnish all transfers to the foil.
