What can and cannot be washed in a dishwasher?

A dishwasher is bought at home for various reasons. The main reasons for its acquisition - saving time, effort and water. Anyway, the dishwasher is an extremely useful appliance in the household. But with all its positive qualities, manual washing cannot be avoided, since not every type of dish can be washed in this miracle of technology.

What kind of dishes in the dishwasher can not be washed, including the device itself. In each model of technology, there may be certain functions that allow the washing of material that is inadmissible in another model. However, there are general rules for washing dishes in the dishwasher.

What are the differences in washing methods?

Manual washing and automatic differ fundamentally. The point is not only that in the first case you have to work with your hands. Unlike manual washing in a dishwasher, there are such components dangerous for dishes as:

• High temperatures created by both water and steam, air;
• Strong heads, jets of water;
• Chemistry contained in the detergent;
• Long stay in such extreme conditions.

Thanks to these parameters, it becomes clear that a number of materials simply can not withstand such conditions.

What utensils should not be washed?

The first thing when buying a dishwasher is to forget about aluminum utensils. This metal behaves extremely poorly in extreme washing conditions. Aluminum dishes after washing in a dishwasher are overgrown with a dark coating, which subsequently is not easy to remove. The alkaline compounds contained in the tablets for washing are to blame. They negatively affect aluminum utensils. If we talk about such dishes of the Soviet years, then irreparable consequences can occur with it - through rusting.

Modern utensils made of this metal are more protected from adverse factors, because after a dishwasher it simply darkens, although this is enough to send it to the trash bin. Spoiling dishes made from this element is very easy. The same fate can be expected from cutlery or kitchen utensils that partially contain aluminum.

Aluminum does not end with the list of metals that will suffer if they are placed in the dishwasher. Silver and copper are also forbidden to be washed in a sink, due to a negative reaction with the chemical composition. Upon contact with the product, silver will darken, like aluminum, and copper will become coated with black spots on the surface. Cupronickel spoons, forks, cup holders and other components of sets are subject to the same effect.

The list of prohibited dishes for placing in an automatic dishwasher is continued by the multicooker bowl. Such a universal “pan” is a complex dish. It is not just made of metal. The multifaceted functionality of such a bowl is achieved by a special surface that does not withstand the environment of the washing chamber. If you neglect this, then very quickly such a bowl will be unsuitable for further use.

Wood products, whether it be a cutting board or a knife with a wooden handle, should not come in contact with water that has the same temperature as in a dishwasher. Water with prolonged contact is detrimental to a tree that swells and further cracks when dried. And in the case of very hot water with alkali content, this process will occur several times faster.

It is extremely persistently forbidden to wash clay pots in the machine. The reason lies in the porosity of such a material. The pot will not be destroyed, but its walls will absorb detergent from time to time. Subsequently, the pots will get an unpleasant odor.

Also, do not wash enamel pans in the dishwasher. Under certain conditions, far from ideal, enamel will quickly crack and such dishes cannot be used for their intended purpose.

Closes the list of dishes prohibited from washing in a dishwasher antique porcelain. Although there is much where you can find information that porcelain is allowed to be placed in the dishwasher - this is about modern porcelain. Currently, this material is much more protected from external factors. In dishes made of porcelain, painting on it is often important. It is she who can suffer primarily from an aggressive environment. When the porcelain service was passed down from generation to generation, it is very sad to put an end to this due to the use of modern technology.

What is undesirable to wash?

In addition to utensils that are strictly forbidden to be washed in a machine, there are several types of kitchen utensils that are undesirable to wash in it. This means that most likely there will be no serious consequences from one time, but the risk of spoiling both the dishes and the dishwasher itself remains.

Crystal. In general, crystal is suitable for cleaning it in a car, but in this case we are talking about thin crystal. Typically, dishes made of thin crystal are made abroad. In this case, it is necessary to use an operating temperature of no higher than 50 degrees. The second important condition is the need for free placement of such dishes in a niche so that the crystal does not come into contact with anything else.

Thermos is a sealed container, and this is the main danger during automatic washing. If the thermos is made of stainless steel, then it is possible to wash it without using the product. Otherwise, there is a possibility of loss of tightness, which will lead to the futility of the thermos, as such.

Kitchen knives in the dishwasher can be washed. But the undesirability of such actions is the danger of damaging the device itself. The blades will also be harmed - they will become dull. Therefore, if there is no wooden parts in the knife, and sharpening is planned ahead, then, as a one-time event, the knives have the right to be washed in the dishwasher.

It is undesirable to wash and cast-iron utensils in the machine. The fact is that after several sinks, it will begin to rust, previously covered with white coating. For this reason, it is advisable to wash the cast iron by hand.

If there is a desire to wash a baking sheet in a dishwasher, then there are no questions to the material, but there is another problem. As a rule, you do not want to wash a baking sheet when it is all hopelessly stained with fat. This thick consistency will certainly be washed off, but with frequent such an event, the filter itself or the filter of the machine itself is inevitable. But it, in turn, is not cheap, it is much cheaper to wash a baking sheet or other greasy dishes with your hands.

What is allowed to wash?

Having understood that it is impossible to wash in the dishwasher, it is necessary to determine what washing is allowed in it. Based on this, it is advisable in the future to use mainly dishes from this list so that the dishwasher does not stand idle most of the time.

It was previously said about crystal. But around almost everyone is washing glasses, glasses, glasses, glasses of this glass in the car. So is it possible to wash crystal glass dishes in the dishwasher? Mostly yes. The ban applies only to thin crystal. In this case, it will not be superfluous to familiarize yourself with the pictograms on the packaging and find the permit icon there. If the box does not exist for a long time, then evaluate the quality of production on your own and make an appropriate decision.

Stainless steel is absolutely indifferent to detergent and temperatures, therefore, dishes from it can be operated in the machine without restrictions.

Ceramic products. Apart from special modern dishes made from the calculation of washing in a machine, ceramics better than all other materials endures the difficult conditions of the machine. The only thing that needs to be done is to make sure that the plates do not touch each other.

Plastic dishes. Today it is she who occupies the lion's share of all the dishes in the kitchen. It can be plates, mugs, containers, shapes. You can relate to a material such as plastic, but it is just perfect for washing in a car. Perfectly able to withstand temperature and chemistry, such utensils will also remain unharmed from bumps and touches.

Baby bottles made of plastic, namely most of them today, can be washed under one condition. It is necessary to take into account that this is children's dishes. And this means that it should be washed with minimal use of chemistry. This can be achieved either simply without adding the product, or using a special tool designed for children's dishes.

It is allowed to wash and pans in the dishwasher. They most often do not want to be washed with hands. However, it is better to make sure that there is an appropriate pictogram on the packaging of the pan. A too oily pan is better to rinse in the sink beforehand, since fat adversely affects the filter of the machine.

As advice

As it became clear, the dishwasher, although a great invention, still remains far from a universal remedy. It is impossible to wash everything that is desired in it, since the rules contain a small list of restrictions. But over time, all the nuances become clear and taken into account, leading to a partial replacement of the dishes in the kitchen.

For a better understanding, below is a list of materials, divided into categories, depending on tolerance to the extreme environment of the dishwasher.
