What dishes should not be washed in the dishwasher?

Buying a dishwasher can turn into a whole problem for those who do not know what can be washed in a dishwasher and what cannot. Of course, it is best to replace all dishes with a suitable dishwasher, and then no problems.

But if this is not possible, then, one way or another, some items still have to be washed with your hands. The fact that you can not put in the dishwasher and further narration will go.

What is the dishwasher exposed to

Why can one put dishes into a car without problems, and the other way around is not even worth trying to wash in a dishwasher? The fact is that inside the washing chamber certain conditions are created that affect the material for making dishes. These conditions include:

• high temperature
• strong chemicals;
• long stay in contact with water;
• forced drying with hot air.

Today, dishes are made from a variety of materials, these include: glass, porcelain, iron, silver, aluminum, nickel silver, plastic, cast iron, crystal, earthenware, ceramics, teflon and others. But even porcelain dishes are different and react differently to hot water and detergents. We will deal with what cannot be put in the dishwasher.

Aluminum products do not fit in the dishwasher

Aluminum cookware is the number 1 cookware that should never be placed in the dishwasher. Aluminum is a metal that reacts with many substances, including water, if certain conditions are created. Under the influence of detergent and high temperature, aluminum products acquire a dark gray coating, and this coating is smeared, leaving marks on the hands.

Out of ignorance, not a dozen people have spoiled in the dishwasher:

• aluminum parts from a meat grinder;
• garlic presses;
• spoons;
• bowls;
• ladles;
• baking sheets;
• pans
• pots.

Note! It is better to replace aluminum utensils altogether, it harms the human body. At the very least, you should use such utensils to a minimum.

Some aluminum dishes are darker after just washing, some only after a few sinks. Therefore, there are those who wash everything and say that nothing will happen. If you ruined aluminum dishes, then in the article Why you can not wash aluminum dishes, you will find tips on how to clean it.

Wood and plastic dishes

What kind of wooden objects and utensils do people shove into a dishwasher, and then clutch their heads, not understanding what happened to their favorite cutting board, rolling pin or wooden spoon. Meanwhile, everything is explained simply. A tree has the property of swelling from prolonged exposure to water, wood fibers are saturated with moisture and increase in size, respectively, the wooden product itself increases in size. When a wooden object dries, the fibers shrink sharply, and the strong bond between them breaks down.

What is the result? But in the end, a wooden object is deformed, ugly cracks appear on it, it loses its appearance and “begins to ask for garbage.” Wooden utensils can be saturated with moisture, being in the water for only 30-40 minutes, and in cold water, and if the water hot time is greatly reduced. In a dishwasher, washing programs can last up to 210 minutes, and what do you think will happen to a wooden object that is poured with hot water and chemistry for more than 3 hours? True, it will become completely worthless when it dries.

In a dishwasher, as a rule, they try to wash different objects from wood, and not necessarily it will be dishes, but in most cases this is it, for example:

• rolling pins;
• cutting boards;
• pestles;
• blades for pancakes;
• wooden Toys;
• spoons;
• bowls and stuff.

Plastic dishes can only be washed in a dishwasher under certain conditions. In particular, if the dishes are made of heat-resistant plastic and there is a mark on it that allows automatic washing. Otherwise, plastic dishes and other plastic items cannot be shoved into the dishwasher. In particular:

1. disposable plastic cups, plates, forks, spoons;
2. plastic plates without any marks;
3. sharp-smelling chemistry plastic toys;
4. plastic items with glued elements.

What else should not be put in the dishwasher

Automatic washing restrictions apply not only to aluminum, plastic and wood items. What dishes and other items should not be put in the dishwasher, especially if the machine has a limited choice of washing modes?

• Fine porcelain items. In general, it is not worthwhile to automatically wash products from any other porcelain, but especially from fine porcelain. Porcelain from hot water can crack quite quickly, and if you still turn on the turbo dryer, it will definitely come to an end.
• Cast iron cookware. After the first wash, the cast-iron products may not be anything, especially if the products are large. But after the second or third wash you will see why it had to be washed with your hands. Cast iron cookware will become corroded and lose its appearance.
• Crystal dishes and souvenirs. Crystal also does not tolerate a “date with a dishwasher." Not only that, during the washing process, micro-scratches can remain on it, so it still cracks from the temperature difference.
  
• Dishes with a vacuum lid. Plastic containers, mugs, pans with a lid capable of pumping air, creating a vacuum inside, also can not be put in the dishwasher. The fact is that from automatic washing, plastic containers undergo some deformation, the eye may not notice it, but this leads to the fact that vacuum dishes lose their tightness and air penetrates into it.
• Sharp kitchen knives. As a general rule, so that the knife does not become dull for a long time, it must be washed very quickly under a stream of cool water. If you hold it for 5-7 minutes in hot water, sharpening will become noticeably worse, and if you constantly wash it in hot water, you will have to sharpen it once every 2 days. It is clear that in a dishwasher, where the dishes are rinsed for a long time in hot water, there is nothing to do with a sharp knife.

Note! Besides knives in the dishwasher it is better not to wash any sharp objects at all - they will become dull!

• Copper items. Copper does not tolerate prolonged contact with hot water and detergent powder. From such an aggressive environment, a copper object darkens and loses sight.
• Thermomugs and thermoses. If the manufacturer of a thermo mug or a thermos directly admits washing its products in a dishwasher, you can safely wash it. In all other cases, wash the thermos and thermomug manually.

As part of the article, we tried to answer the question of which dishes should not be washed in the dishwasher. Of course, the list of “prohibited” items is really much wider, but the main thing is to understand the principle and not make mistakes fatal for things in the future. Thanks for attention!
