Yes, vinegar will definitely clean copper especially if you mix it with salt. Vinegar and salt are great for cleaning copper because acidic vinegar strips oxidized tarnish and the abrasive salt help to remove any of the built-up grime.
Clean copper surfaces by boiling a mixture of three cups water, one cup distilled white vinegar and one tbsp. salt. Soak a cotton rag in the hot solution and apply it over the copper surface. Let it cool, and then wipe the area clean.
Tip! Copper is found in many fine household items, such as jewelry and pots. Over time, though, the surrounding air causes the metal to tarnish, and who wants to display tarnished copper?
Tarnishing is a natural process, so it makes sense to use natural items to eliminate the dark, grimy appearance. Commercial copper cleaners often contain harsh chemicals, but you can naturally clean copper with materials usually already found in your home, learn more at MNN.com.
