Metal Cleaners - Copper, Brass, Cast Iron

• Brass cleaner
  2 tablespoons (36g) salt
  2 tablespoons (16g) flour
  1 to 2 teaspoons (5 to 10ml) vinegar
  
  In lieu of a toxic brass polisher, combine equal parts of flour and salt in a small bowl and ass just enough vinegar to make a paste. Use a soft cloth to apply the mixture to the brass item (wear rubber gloves, as this can be a dirty process if the item is heavily tarnished). Rinse thoroughly with water and dry with a clean, soft cloth. This formula can be easily doubled for larger items. TIP: Before attempting to clean a tarnished nrass item, hold a magnet up to see if it really is brass. If the magnet sticks, the object is likely brass-plated and could be easily damaged by the abrasivness of salt.

  1 teaspoon (6g) salt
  1/2 lemon

• Copper Pot Cleaner
  1/4 Cup Vinegar
  1 Tablespoon Salt
  
  
  Soak a clean cloth in the vinegar and sprinkle with salt. Rub over tarnished pots. Rinse thoroughly with water and dry with a soft cloth. 

• tarnished copper
  If you have heavily tarnished copper or copper alloy object to be cleaned up, use a paste made of salt and vinegar. 
  
  
  

• Cast Iron Cleaner
  1/2 Cup Salt
  1/4 Cup Vegetable Oil
  Cast Iron will last and last and last and can be handed down from generation to generation if properly cared for. And cast iron will not leach dangerous 'non-stick surface' coatings into your food.
  
  Never use dish soap in your cast iron cookware. If properly cared for and treated, cast iron can be better then most non-stick pots and pans, a bit heavier however.
  
  Rinse the cast iron skillet with water and scrape out any residue using only wooded spoons or plastic spatulas. Warm the skillet over medium heat for 30 seconds, once dry, remove from heat. Add vinegar and salt mixture and scrub entire surface with wadded up papertowels until clean. Rinse again with plain water and dry over medium heat.
