Not dishwasher safe: These 15 things should never be put in the dishwasher!

Dishwashers are magical devices and a real oneSaving time in the kitchen, but they can damage certain items, and some of them are quite expensive to repair or replace. Which things should never go in the dishwasher? To be on the safe side, you should hand wash these pans and utensils here.

Wooden spoons, bowls and cutting boards

The harshness of dishwasher cleaners can remove the natural oils that keep wooden utensils and cutting boards from drying out. When these oils are removed, the wood becomes cracked. Wooden items should be quickly hand washed with a mild detergent in warm water. Just like wood, pizza stones should be hand washed to avoid cracking and damage from harsh cleaning products.

Can kitchen knives go in the dishwasher?

You should never put knives in the dishwasher for three reasons. First, they can damage the protective coating on racks and baskets, causing rust to form. Secondly, the sharp edges are dangerous when unloading the dishwasher, especially if children help. Finally, dishwashing detergent can dull the knife blade and cause wooden handles to loosen and splinter. It is best to hand wash all types of kitchen knives.

Graters and sieves

All kitchen appliances with sharp edges should not be put in the dishwasher. Graters and strainers can damage the dishwasher's plastic coating and cause rusting. And if you put items with small holes in the dishwasher, it will be almost impossible for the water jet to remove all the food particles. Here too, you will achieve the best results if you wash by hand.

Cast iron cookware

Cast iron pans and pots have been around for centuries and can last almost forever,if you care for them properly. To prevent cast iron from rusting and food from sticking, it must be seasoned with oil. This protective oil layer seals the material and protects it from rust.

When you put cast iron pans in the dishwasher, the detergent and excess water dissolve the oil. They then have to be burned in again. This also applies to enameled cast iron pans.

Aluminum pans and cookware

If you've ever put a shiny disposable aluminum dish in the dishwasher, you know what happens. It becomes dull and darkens. The same thing can happen with your aluminum pots, pans, and baking sheets. If the aluminum has not been anodized, the cleaning agent can cause pitting and corrosion. You may also see white spots on the surface caused by the alkalinity of the dishwashing detergent. Even if the baking tray is marked as “dishwasher safe”, it is better to wash it by hand.

Copper pans and cups

Copper pots and mugs, such as the Moscow Mule copper mugs, are classic and beautiful, but require special effort to keep them shiny. Don't complicate the task by putting it in the dishwasher. The harsh chemicals in dishwasher tablets immediately dull the surface and can attack the copper. Dimples cannot be removed afterwards, even with the best copper cleaner.

Pressure cooker lid

While a pressure cooker or the inner container of an Instant Pot can easily be cleaned in the dishwasher, you should never put pressure cooker lids in the dishwasher. The lid contains the valves that control how the pressure cooker works. Exposure to the dishwasher can allow small food particles to enter the valves and vents and cause the cooker to malfunction (explode). The harsh chemicals can also damage the lid's rubber or silicone seals.

Can non-stick pans go in the dishwasher?

Although many non-stick pans, such as Teflon pans, are labeled as dishwasher safe, harsh cleaning agents and drying temperatures that are too high can attack the non-stick coating. If you wash your pans in the dishwasher, do not use a drying cycle and let them air dry. At the first sign of damage to the surface, it's time for a new pan. If the nonstick coating is scratched, chipped, or peeled, it can release dangerous toxins into the food.

Ceramic pans and cookware

Ceramic pans and cookware are popular because of their nonstick surface. The name is a little misleading because not the entire pan is made of ceramic. Instead, it only has a ceramic coating. A ceramic coating can be applied to cast iron, aluminum, copper or stainless steel. Always hand wash ceramic cookware. Dishwasher cleaners may contain bleach and citric acids that are too harsh on the coating.

Acrylic or melamine tableware

Lightweight, shatterproof acrylic or melamine tableware is very popular because of its bright colors and patterns. Unfortunately, the high water and drying temperatures as well as harsh detergents can ruin the dishes. After several rinses, especially with cheaper sets, hairline cracks and color loss can occur. If you love the dishes and want them to last, you should wash them by hand.

Insulated cups and thermoses

Insulated cups and containers made of plastic and metal are ideal for keeping hot things hot and cold things cold. Most are made of two layers of material with an air space between the two. This air space provides insulation.

While some containers are labeled as dishwasher safe, many are not. It is best to hand wash both plastic and metal insulated containers. When placing a container in the dishwasher, choose the top shelf and avoid the high heat of the drying cycle, which attacks the rubber seal and therefore affects the insulating function. Here are some ways you canbe able to clean a thermos flask.

Printed or hand painted glassware

While commercial printing techniques on glassware have improved, they are not always dishwasher safe. The dishwasher salt and the power of the water spray can remove the paint in just one or two rinses. And what good is a glass measuring cup that doesn't have any lines?Hand painted glasses, even if fired with heat, should never be put in the dishwasher.

Jars with paper labels

Do you want to use an empty pickle jar for food storage? You can easily put the glasses in the dishwasher if you remove the paper labels first. Otherwise, the paper and glue can come loose and clog the dishwasher drain and food disposal system. Here are some of the bestMethods to remove stickers.

Gold cutlery and dishes with gold rims

Gold cutlery can become discolored in the dishwasher. Fine china dishes are dishwasher safe unless they have gold trim or gold trim. The harsh detergent and strong water action of the nozzles can cause the patterns and designs to flake off.

Silver cutlery

Can silver cutlery go in the dishwasher? Basically yes. The exception: Many sterling silver knives have a hollow handle, and the heat from the dishwasher can cause the adhesive that holds the blade to the handle to melt and come loose. This happens regardless of whether the blade is made of sterling silver or stainless steel. Instead, it's better to wash them by hand.
