What shouldn't be washed in the dishwasher?

Cast iron cookware

Cast iron pans and cauldrons cannot be kept in water for a long time, this will wash off the protective fat layer, which the material absorbs during cooking. As a result, the metal begins to rust.

It is better to wash dishes made of cast iron by hand immediately after cooking and wipe dry with a towel.

Aluminum and Silver

Cutlery made from these metals tend to blacken and leave dark marks. This happens under the influence of high temperature and synthetic detergents. It is almost impossible to clean dark stains from spoons, forks and knives, as well as dishwasher walls.

Be sure to look how to clean the oven from fat.

Copper and brass

After the dishwasher, copper or brass cookware will lose its luster. Moreover, from aggressive detergents, the metal will oxidize and stains will appear on the surface, which cannot be eliminated.

Natural wood items

Wooden boards and paddles do not tolerate temperature extremes and prolonged exposure to water. After a couple of loads in the dishwasher, they will dry out and crack.

AND the main problem not that they will lose their aesthetic appearance, but that bacteria multiply in the cracks.

Thermos

If you want the thermos not to lose its heat-retaining properties, always wash it by hand. The heat-insulating layer is washed off from the intense exposure to hot water and the thermos will not keep the temperature.

Sharp objects

It is better to wash knives, graters and peelers by hand. Firstly, in the dishwasher, they blunt several times faster. Secondly, sharp edges can damage parts of household appliances. And thirdly, often the handles of knives are made of wood, for which automatic washing is also contraindicated.

Non-stick cookware

Plastic utensils

Whether or not to wash food containers in the dishwasher is a controversial issue. The appearance of plastic dishes does not deteriorate, but if you purchased a budget container, then, under the influence of hot steam, harmful substances can be released from the material.

In addition, plastic tends to absorb substances, including those found in dishwasher tablets. Therefore, it is safer to rinse the container under the tap.

Porcelain

Some porcelain items bear a sign stating that washing in a car is prohibited. As a rule, these are dishes with glaze and gilded elements on the walls. Over time, they can become thinner and ruin the exquisite appearance of the product.

Crystal

Fine crystal products are easily damaged. Hot water makes them cloudy, and shaking causes cracks.

After washing, the crystal should be immediately removed and wiped dry.
