If you have some metal in need of polishing but you're not a fan of using noxious-smelling commercial metal polishes, this simple DIY recipe is surprisingly effective.
DIY and design blog Pancakes and Fries shares this terribly simple recipe:
In a glass or plastic bowl (never metal) mix 2/3 cup distilled white vinegar with 2/3 cup flour. All I had was whole wheat flour, so my cleanser is for heart-healthy tarnish. Once the mixture is smooth, add 1/2 cup of salt and stir until mixed in. This isn't the sort of thing that keeps well, so make this polish on an as-needed basis.
Slather all the brass pieces with it, leave them overnight so the mix can dry onto the metal, and in the morning throw them in a sink of hot water to rinse off the mixture. You'll have sparkling metal without having to use stinky and toxic polish — and the enormous amount of elbow grease required to really polish up a well-tarnished item.
