How to Maintain Copper’s Shine?
Maintaining copper’s shine requires regular care. Here are some tips to keep your copper looking its best:
- Avoid Dishwashers: Always wash copper items by hand to prevent tarnishing.

These practices help in preserving the copper’s natural beauty and prolonging its life.
Why Does Copper Tarnish?
Copper tarnishes due to a chemical reaction with oxygen and moisture in the air, forming a layer of copper oxide. This tarnish can appear as a dull, dark surface on the copper. While some people appreciate the aged look of tarnished copper, others prefer it to be shiny and bright.
How to Remove Tarnish from Copper?
To remove tarnish effectively, you can use a variety of methods. Here are a few options:
- Ketchup Method: Apply a thin layer of ketchup on the copper, let it sit for 10-15 minutes, then rinse and buff.
- Baking Soda Paste: Mix baking soda with lemon juice to form a paste, apply it to the copper, then rinse and dry.
These methods utilize everyday household items to restore copper’s shine without damaging the surface.
