Let this simple solution of cream of tartar and hydrogen peroxide do the hard work of removing a bathtub stain for you. Fill a small, shallow cup or dish with cream of tartar and add hydrogen peroxide drop by drop until you have a thick paste. Apply to the stain and let it dry. When you remove the dried paste, you’ll find that the stain is gone too.
Discolored aluminum pots will sparkle again if you clean them with a mixture of 2 tablespoons cream of tartar dissolved into 1 quart (1 liter) water. Bring the mixture to a boil inside the pot and boil for 10 minutes.

Here’s a recipe for fun dough that’s like the famous commercial stuff: Add together 2 tablespoons cream of tartar, 1 cup salt, 4 cups plain flour (without rising agents), and 1-2 tablespoons cooking oil. Stir well with a wooden spoon to mix together, then slowly stir while adding 4 cups water. Cook the mixture in a saucepan over a medium flame, stirring occasionally until it thickens. It’s ready when it forms a ball that is not sticky. Work in food coloring, if you want. Let it cool, then let the kids get creative. It dries out quicker than the commercial variety, so store it in an airtight container in the fridge.
