In 1914 Congress officially made the second Sunday in May "Mother's Day." Ever since, grown sons and daughters been doing something special for Mom like visiting, taking her out or having her over for dinner. This year, if your plan is the latter, and the family silverware is looking tarnished from non-use and storage, we have a simple solution. When your silver's shine has gone away, there's an easy way to save the day. First cover the bottom of a heat-resistant glass dish with aluminum foil, shiny-side-up. That's important. Place the tarnished silver on the foil; add 1 teaspoon of baking soda and pour in enough boiling hot water to cover it. In no time at all the tarnish will be on the foil. Mom will be impressed! And that's the On The House tip for today.
