What dishes can not be washed in the dishwasher

The problem is that some types of dishes and kitchen utensils should not be washed in an automatic car, due to the fact that quite extreme conditions are created in the washing chamber to achieve absolute cleanliness. The cookware is exposed to prolonged exposure to very hot water with the addition of strong chemicals, and at the end of the cycle is subjected to forced drying with a stream of hot air. Not every material or coating can withstand such an intense impact without unpleasant consequences. To know which one is not recommended to wash in automatic mode, before using it is required to carefully study the instructions for the dishwasher.

Metal utensils

Not all metal utensils can be washed in the dishwasher, it depends on the type of material from which it is made. It is necessary to completely eliminate those kitchen items that need to be washed at a low temperature using non-aggressive detergents:

• Aluminum - an active oxidation of this metal occurs in the dishwasher. This is due to both exposure to very high temperatures, and the use of alkali, which is part of the detergent. If you take aluminum dishes from the dishwasher, then black spots will remain on your hands - this is aluminum oxide.
• Silver - after processing in the dishwasher, dark spots appear on their surface, the appliances themselves become dull and faded. Silver is generally recommended to be washed separately, avoiding contact with other metal utensils, oils, and acids.
• Cast Iron - a negative effect will manifest itself over time, especially - if we are talking about large massive pans. Already after the third or fourth washing, the surface will show signs of corrosion, and the food during cooking will stick, sticking to the surface of the frying pan.
• Copper - prolonged contact with detergents and hot water is contraindicated. In a fairly aggressive environment, copper begins to darken, losing the warm golden tint of
• Melchior, characteristic of it, because of the prolonged exposure to hot water, it loses its luster, darkens, and the coating begins to peel.

Wooden utensils

Kitchen utensils made of wood is highly undesirable dishwasher safe. This is due to the peculiarities of the structure of the tree. With a long stay in the water, the wood fibers begin to absorb moisture, the wooden product begins to swell, increasing in size. In order for wooden dishes to be saturated with moisture, even in cold water it will take about 30-40 minutes( for reference, one cycle in the dishwasher can last up to 3 hours).

In warm water, this time is significantly reduced, moisture absorption is much more intense. When drying( processing dishes with hot air), there is a sharp and uneven decrease in the moisture content of the fibers, they begin to shrink. As a result, cracks appear on the wooden object, it is deformed, loses its attractiveness and aesthetics. Therefore, to ensure the safety and long-term operation of kitchen utensils made of wood, it is better to rinse it with your hands in warm( not hot) water.

Important:

Do not wash dishes that contain wooden elements in the dishwasher, for example, pans or chopping( cooking) knives with wooden handles.

Plastic Tableware

It is allowed to load into the dishwasher only the dishes made from special heat-resistant plastic. Usually it has a special sign indicating the possibility of automatic washing. If there is no such sign, you should not risk it and use a dishwasher to wash plastic dishes. In addition, you can not put all disposable dishes, as well as plastic objects that have glued objects. Another sign that indicates the unsuitability of plastic dishes for washing in an automatic machine is a sharp characteristic "plastic" smell.

What else is not worth washing in the dishwasher

Note additionally, what kind of dishes can not be washed in the dishwasher:

• gold-plated objects - wash only with your hands, this will preserve their presentable appearance. For gilding the aggressive environment in the dishwasher is absolutely not suitable, detergents literally wash away a thin layer of precious metal. This rule also applies to porcelain cups with a gilded pattern.
• crystal is very sensitive to sudden temperature changes that can lead to the formation of cracks. In addition, small vibration can cause almost invisible scratches. Over time, when these scratches become quite a lot, this will cause the surface of the crystal to become turbid, losing its special, unique luster
• fine china - does not tolerate sharp temperature drops, and when it is processed with hot steam, its surface can simply crack.
• sharp knives -the knives themselves will have nothing, but they will lose their sharpening. Experience shows that even if just holding the knife in hot water for 5-8 minutes, it will become noticeably dumber. After washing in the dishwasher, the knives will have to constantly sharpen
• utensils with a teflon coating - by itself it does not require much effort when washing, because with proper use, the food does not stick to the bottom of the pan or frying pan. Therefore, such dishes must be washed manually with warm water, using a minimal amount of non-aggressive detergent. In the dishwasher, due to a fairly intense exposure, the Teflon coating wears out quickly, which leads to a significant reduction in the life of such dishes.
• vacuum dishes - plastic pans and containers, the lids of which allow air to be pumped out to ensure long-term storage of food. Due to the treatment with very hot water in an automatic car wash, plastic may slightly deform. And although these changes are almost imperceptible to the human eye, the lid will no longer be completely tight against the walls, so the tightness of the dishes will be lost.

Automatic washing of thermo mugs and thermo mugs is allowed only in cases where the manufacturer has indicated such a possibility. Otherwise, they should be washed by hand.
