8 things you should never put in the dishwasher

A dishwasher is a universal device that many housewives dream of. Such a device can easily cope with washing all the dirty dishes left after a noisy feast, and no one needs to stand at the sink for hours. But not all materials are suitable for this method.

The American edition of Lifehacer told us what dishes should not be put in the dishwasher.

1. Dishes made of wood

Wooden boards, spoons and knives with wooden handles should not be washed in the dishwasher. Hot water contributes to the deformation of such material. And during the drying process provided by the dishwasher, the wood can crack. It is enough to simply wipe and wash such dishes by hand in warm soapy water, and then dry them.

2. Glass and crystal

These dishes are usually painted or gilded, and the dishwasher destroys such things. In addition, crystal and glass are very delicate materials, so they can easily crack or break.

3. Cast iron and copper

If the cookware produces well-seasoned, naturally non-stick, evenly distributed heat, you need to treat it properly. The potentially corrosive climate of the dishwasher is not suitable for such cookware and will cause rust. Plates or pots made of this material should simply be wiped with a soft cloth or washed in mild soapy water and dried well with a towel.

Copper provides excellent thermal conductivity and tends to tarnish. Therefore, do not put this high-quality material in the dishwasher, otherwise it will become dull and lose its color.

4. Non-stick pots and pans

The coating of nonstick pots and pans can easily peel off when exposed to high temperatures, water pressure, and repeated rotation. Harsh detergents can further damage the surface and render the cookware unusable.

5. Knives

The abrasiveness of the detergent will dull the blades of knives, and they will need to be sharpened more and more often. In addition, hot water weakens the handles and causes rust over time.

6. Graters.

First, just like with sharp knives, dozens of tiny blades can become dull in the dishwasher over time. Secondly, the small holes trap food particles that even strong gusts of dishwasher water may not remove. It is better to wash such dishes with a brush.

7. Thin plastic

The plastic of some containers (for example, for sour cream or margarine) is too thin and soft to withstand the heat of the dishwasher - many of them will melt, deform, and simply not close after one cycle.

8. Sticky labels

Particles of sticky paper labels can clog the filter or drain, causing a potential need for repairs in the future.
