Copper cooking ware is like the royal ensemble for kitchen utensils, people flock to it because of its regal and classy aesthetic. Not only will food look better prepared in copper pots and pans, but some claim that it also tastes better. Of course, no one thing is perfect. If copper pots and pans are not maintained well, they can get damaged easily as copper is a very brittle metal. For instance, what most people do not know is that dishwashers are not friendly to copper cooking ware. As such, it is important to be careful when handling copper and not put it into the dishwasher. Read on to find out why!



Tarnishing and discolorations

While it seems tempting to simply toss all the used pots and pans together into the dishwasher, you might want to consider washing the copper ones with your own hands. While some copper can still be placed into dishwashers as they are dishwasher safe. The only downside is that dishwashers have no limit on the strength used to clean which could cause damage to copper cookware. By putting it in the dishwasher, you risk the utensils becoming tarnished or discolored. Plus, scratches can easily form which means that the copper utensils are no longer as flawless as they should be.

When you place a copper pot or pan into a dishwasher, it becomes exposed to pressurized water and harsh chemicals which will cause the wear and tear of the cooking ware. As such, copper cookery should be washed by hand as you will be able to control the strength that you use and also the detergent.

Food might remain on the bottom

While copper pans may make your food taste better, when the ingredients you cook get burnt, they tend to really stick to the pan, which can cause mold problems. If you get it on the bottom, it sticks even more. Putting it in a dishwasher will not focus on the problem area since the dishwasher does an overall cleaning of the utensils. In fact, most stains like that are rarely removed completely in a dishwasher.

Some people suggest that you can turn up the pressure but as mentioned above, this tends to cause more damage to your copper cookery. You risk tarnishing and discoloring the pan while the stain still remains stuck on stubbornly.

Inner lining gets removed

Every metal reacts to natural elements in our environment, this applies to copper in particular. This is why manufacturers include an inner silver lining that prevents the copper from reacting to the food. If food were to absorb too much copper, consuming it could be a major health risk. People can be adversely affected by this.

So, washing your copper pots and pans in a dishwasher is not safe because the pressure of the dishwasher not only washes away the surface, it could penetrate through the silver lining as well. So, every time you cook, you might unknowingly make a highly toxic metal. The health hazards that copper poses to the inner workings of our body are extremely undesirable like liver failure and in worst-case scenarios, death. The protective silver lining itself is very thin which is why it is susceptible to getting washed away by the dishwasher.

Shape deformation

If you are unaware, copper is one of the softest metals out there which means that it is more malleable than its steel or iron counterparts. Plus, metals are heated in order for their shape to be changed. Imagine putting a copper pot or pan under high heat and pressurized water in a dishwasher. The results would be very different-looking cookware as compared to when you first placed it in the dishwasher.

This would not be a problem if you have an artistic flair and enjoy that but it would also be more advisable to buy a canvas for that. Copper pots and pans are rarely inexpensive, one of them can easily cost up in the high tens. It would not be worth it financially to pay for a utensil that ends up doing what you do not want it to do. You want to cook proper food with the copper cookery but the deformed shape of it would certainly make that a challenge.

Best Ways To Clean Copper

We hope you are convinced by now that the dishwasher is the last way you should be washing your copperware. The best method is still to do it by hand yourself. Of course, there are times when washing by hand alone might not work but there are various other home remedies that can work that out.

For example, if your pot has burnt food stuck to the bottom of it that is difficult to wash off, do not just increase the strength you are using as you could risk scratching your pots and pans too. You can just soak the affected area in hot water to loosen up the food and remove it with greater ease after that.

Otherwise, you can also try the lemon juice-baking soda trick or vinegar and salt solution too. These are solutions that you can leave on the affected area which will make the stains easier to clean. Just let the solution rest on it before rinsing and scrubbing it off.

Lastly, when you are done washing the cookware, do not just leave it out in the open to dry. Use a dry cloth or towel to dab it dry so that it does not leave any water stains. These are stains that form as a result of pans being air-dried. These stains can be quite unsightly so it is advisable to go the extra mile to prevent this staining from happening.


In conclusion, dishwashers are definitely not the friendliest to copper pots and pans. Tarnishing, discolorations, the release of toxic elements, and shape deformation are things that can happen to your copper cookery which you would want to avoid. As such, if you can, just use your hands to delicately clean it up instead of the dishwasher.
