8 Things You Should Never Put in the Dishwasher

Things You Should Never Put in the Dishwasher

A dishwasher is a household appliance used to clean dishes and kitchenware. They come in various sizes and can be portable or built-in. They are often luxury items, but they can save you time and energy when cleaning dishes. Like most people, you probably put many things in it. After all, it’s easy to pop everything in and let the machine do its thing. However, there are some things that you should never put in the dishwasher. If you want your dishes to come out clean, then avoid putting these ten items in there: 

Here is a list of ten things you should never put in your dishwasher.

1. Cast iron pans:
Cast iron pans coated with a layer of oil or seasoning that helps to protect the pan and prevent food from sticking to it. When you put a cast iron pan in the dishwasher, this coating is stripped away, leaving the pan vulnerable to rust and corrosion. Additionally, the high temperatures and harsh detergents used in dishwashers can damage the finish of your cast iron pan.

2. Delicate china or glassware:
Dishes like fine china or crystal glassware are damaged by the high temperatures and harsh chemicals in dishwashers. They’re best washed by hand as well.

3. Non-stick cookware:
You might think that since your dishwasher gets hot, putting your non-stick cookware in will be okay. However, this is not the case. High temperatures and harsh detergents can damage the cookware’s non-stick coating. That means that food will start sticking to it and will be harder to clean. So, it’s best to wash your non-stick cookware by hand.

4. Silverware:
If you have any particularly valuable or sentimental silverware, it’s best to hand wash it. Silver is a precious metal; over time, it can discolor and even tarnish from the chemicals in dishwashing detergent. If you must put your silver in the dishwasher, use a mild detergent and the lowest temperature setting. 

5. Dishes with grease:
Dishes with a lot of greases should be washed by hand. The dishwasher can’t effectively remove all of the grease, and it can end up costing other dishes in the cycle.

6. Plastic containers:
Plastic is a porous material that can absorb water and other liquids. If you put your plastic containers in the dishwasher, they will warp and crack.

7. Stainless steel cookware:
Stainless steel cookware is fantastic because it’s virtually indestructible. But the harsh chemicals in dishwashing detergent can damage your stainless steel finish. So it’s best to hand wash it.

8. Wooden cutting boards:
Wooden cutting boards are porous, which means they can absorb water and retain bacteria. Dishwashers use high temperatures and harsh chemicals to clean dishes, which can damage the wood and cause it to crack. It’s essential to clean your wooden cutting board after each use, but you should never put it in the dishwasher.

How to Give Your Dishwasher a Deep Clean

You can do a few things if you want your dishwasher to stay clean. First, ensure that you scrape off any food from your dishes before putting them in the dishwasher. That will prevent food from building up and becoming difficult to remove. Run hot water in your sink before starting your dishwasher. That will help to remove any grease or food that may be on your dishes. Finally, regularly clean your dishwasher itself. That is done by running a cycle with vinegar or using a commercial dishwasher cleaner. By following these tips, you can ensure that your dishwasher stays clean and runs efficiently.
