Have your copper pots, measuring cups and beer mugs lost their luster? If your copper kitchen gadgets are looking dull, it might be time to polish it to restore its original beauty. Here's everything you need to know about how to clean and polish copper to keep it looking great for years to come.

How to Clean Copper Cookware?
The best way to clean copper pots and pans is with warm water and dish soap. Use a soft, gentle cloth, brush or sponge to wipe away any residue. To remove stuck-on food, soak the pan in hot, soapy water for 15 minutes and scrub again.
It's important to avoid using harsh, abrasive cleaning tools or harsh cleaners like Bon Ami on your copper pots and pans. After washing, always hand dry your copper pots and pans immediately. Allowing them to air dry will leave water spots and cause the metal to tarnish faster.
Can you put copper cookware in the dishwasher?
Copper cooking gadgets should be hand washed and never in the dishwasher.
The exception is copper-colored cutlery and other kitchen utensils. They are made of stainless steel that has been coated with a copper-colored coating, but do not actually contain copper. It's best to double-check the manufacturer's instructions, but generally, these items are dishwasher safe.
How to tell if copper is lacquered?
Some copper cookware is prized for how its material interacts with what's inside. For example, a copper mixing bowl helps keep egg whites steady while you're beating them, and a copper pot's smooth surface and ability to conduct heat are great for making jam.
However, some copper cookware is lacquered to give it a shiny, reflective finish, rather than the subtle sheen of unlacquered copper. Lacquering also prevents copper from tarnishing, so if the cookware doesn't develop a slight patina over time, it's most likely lacquered. You can always check the packaging or check with the manufacturer to make sure.

How to Clean Lacquered Copper?
To clean lacquered copper cookware, simply wash it in warm, soapy water, rinse well, and hand-dry it with a soft, clean cloth.
How to Clean Lined Copper?
Some copper cookware is lined with tin or stainless steel on the inside to provide a non-reactive cooking surface. These items should be thoroughly cleaned and dried by hand. You can polish the copper exterior of these items, but don't polish the tin or stainless steel lining.
Be aware that copper cookware that is lined with tin may darken and develop a patina over time. These items may also need to be re-tinned after years of use. Exposure of copper flakes through the tin lining indicates a need for re-tinning.
How to Remove Rust from Copper Pans Without Chemicals?
Over time, even clean, unpainted copper can develop a slight rust from interaction with oxygen, moisture, dust, sunlight, heat, and the oils on our hands. If left unchecked, metals will corrode over time. Rust will look like brown or black spots or dark areas, rather than a shiny, even surface.
For items that don't come in contact with food, if you find this patina attractive, you can keep it. But if you plan to use the item in your kitchen, you will need to polish off the rust. Be aware that because copper is reactive, it is recommended to avoid cooking acidic foods like tomatoes and lemons in unlined copper pans. Doing so can cause the copper to leach into the food and make you sick.
You don't need to invest in harsh chemical cleaners. The basic recipe for cleaning copper requires acid and salt.
How to Clean Copper with Ketchup or Tomato Paste?
One way to treat light tarnish on copper is to apply a mixture of two parts ketchup or tomato paste and one part coarse salt to the copper surface. Let the paste sit for a few minutes, then rinse and hand dry the pan.
How to Clean Copper with Lemon and Salt?
For stubborn copper tarnish, you can try dipping a cut lemon in coarse salt and then rubbing the cut surface over the surface of the pan. After a few minutes, you should see the copper regain its luster. Once it reaches the brightness you like, wash the item with dish soap and water, then hand dry thoroughly.
How to Clean Copper with Vinegar?
Really tarnished items can benefit from heat in addition to acid and salt. This method works well for items that can fit in a larger pot on the stove.
Place one cup of white vinegar, three cups of water, and one tablespoon of salt in a large, non-reactive pot and heat over high heat. Place the tarnished item in the pot, submerge it in the liquid, and bring to a boil. When you see the tarnish on the copperware come off, turn off the heat and let the pot cool. Remove the item and use another method to remove any remaining tarnish.
