Sharp Knives

Sharp knives are an essential tool for many kinds of cooking; however, it is important to remember never to put them in the dishwasher. Not only can knives warp and become dull due to exposure to high temperatures, but they can also damage plates and other items in the dishwasher and pose a safety hazard if you ‘grab in the dark’ when unloading.
To help keep your knives sharp and clean, it is best to hand wash carefully using mild soap and water. Ensure that all cleaning products used will not rust or corrode the blade in any way before use, as this could cause damage to the knife and any food it comes into contact with later on. Cleaning knives by hand requires a little extra effort, but it is ultimately worth it for superior performance in your kitchen.
Copper Pots And Pans

Although throwing your favorite copper pots and pans into the dishwasher might seem convenient, this is a surefire way to damage them. Copper is a particularly soft material that can quickly lose shape and luster when exposed to high temperatures, like in a dishwasher.
Not only will this reduce the life of your cookware by dulling their appearance, but it could also make them unsafe to use, as the heat may warp them and make them uneven. Instead of attempting to clean copper cookware in the dishwasher, opt for hand-washing – simply soak them in warm soapy water and clean with a mild detergent or baking soda using a soft cloth, and they’ll maintain their vibrant luster far longer.
Crystal

Crystal is a type of precious glassware that consists of lead oxide, which helps make the glass strong and durable. Unfortunately, putting Crystal in a dishwasher can greatly damage the delicate glassware over time. The combination of excessive heat, detergents, and the intense cycle of a dishwasher can be very hard on Crystal and cause it to break or scratch.
Crystal also has an even higher risk of cracking when exposed to changing temperatures, so it’s best not to place it near hot and cold sources. Even if your Crystal is labeled as dishwasher safe, it is still far better to hand wash it as that is much less trying on the beautiful glass. In short, when washing and protecting your Crystal, take extra caution; hand washing is always best.
Pressure Cooker Lids

Pressure cookers are a great way to save time and energy when cooking, but the lid should never be put in the dishwasher. Running the lid through a hot water cycle in the dishwasher can cause deformation, affecting its ability to close properly. This is because pressure cooker lids must fit perfectly to create a good seal, allowing the food to cook correctly under high pressure.
Additionally, certain materials of pressure cooker lids will also erode much faster if they’re exposed to detergents or extreme temperature changes regularly. For these reasons, it’s best to hand wash all pressure cooker lids using warm water and non-abrasive soap. That way, you don’t have to worry about any adverse effects on your equipment, and you can still ensure that your food is cooked correctly every time!
