Why should you not clean a copper saucepan with vinegar?

Here's why:

* Corrosion: Vinegar reacts with copper, forming a green patina (verdigris). This patina is not only unsightly but also toxic.

* Dullness: The reaction with vinegar can also dull the copper's shine, making it look old and worn.

* Weakening: Over time, the repeated use of vinegar can weaken the copper, leading to potential damage and leaks.

Instead of using vinegar, here are some safe and effective ways to clean your copper cookware:

* Salt and lemon: Sprinkle salt on the copper surface and rub it with a cut lemon.

* Baking soda paste: Mix baking soda with water to form a paste, apply it to the copper, and scrub gently.

* Commercial copper cleaner: Use a specially formulated cleaner designed for copper.

Remember to always rinse your copper cookware thoroughly after cleaning and dry it completely to prevent water spots.
