Can clay pots be washed in the dishwasher?

What materials should not be put in the dishwasher

Since machine detergents are much more aggressive than handwashing, and the water temperature reaches 90 degrees, you cannot put porous, fragile and easily rusted items in the device.

What pans can’t be washed in the dishwasher:

DO INDIAN VESSELS WORK IN A DISHWASHER? Aluminium, Iron, Stainless Steel, Melamine in Dishwasher

  • Salad and soup bowls in the form of pots (made of thin faora or glass, majolica, in the technique of Gzhel, Khokhloma, etc.). п.). Brittle materials tend to crack, turn cloudy or lose their glaze because of vibrations and overly hot water.
  • Clay and ceramic baking pans, but without a glaze. these materials absorb detergent intensively and are reluctant to give it away when rinsed, so that the dishes will be toxic at the end.
  • Teflon-, ceramic- and other non-stick coated saucepans without a special protective layer. after several washes such saucepans will “peel off” to the aluminum or steel base and lose their key properties. Bowls from multicookers fall into this category. they require only manual cleaning.
  • Aluminum bowls. usually cleaning in the dishwasher is a disaster. Detergents strip away the protective oxide film, the metal reacts with the water. The result: tarnishing and no longer suitable for food use.
  • Cast-iron cauldrons and pans. this cookware is too heavy and easily injures the fixtures, but most importantly. the material rusts from prolonged moisture, and in the dishwasher, the tab is usually left until morning.
  • Any pots with wooden or plastic handles, not designed for high heat.

A separate word about the enameled crockery. If it’s iron and chipped, it will rust in the dishwasher. If the enamel is old or cheap, it cracks quickly. But expensive, high-quality enamel over cast iron is one of the best solutions. It won’t come off and keep the metal from oxidizing. The only limitation is the weight. You can still put a small 2-liter saucepan in the tray, but you shouldn’t put a 5-liter cauldron.

Tip Even a very good enamel will last longer if you don’t abuse it with too aggressive detergents. Therefore, cleaning in the washing machine is acceptable, but not desirable.

Which pots can be washed in the dishwasher without restriction:

  • stainless steel;
  • Small cast-iron with high-quality enamel;
  • Glassware for baking and microwave cooking (designed for high temperatures);
  • modern (and usually not cheap) pots with a protective layer over ceramic or non-stick coating, preferably steel, not aluminum in the base.

Tip The information on whether the pot is allowed automatic washing, be sure to be on the bottom or in the instructions to the pot. Pay attention to the icons before buying.

Advantages and disadvantages

Over the long history of the use of clay as a material for creating cookware, the technology of its manufacture has improved significantly. Ceramic cookware has become more durable and has acquired a modern look.

Among the unambiguous advantages of the material are the following facts:

  • environmentally friendly material, natural raw materials in the composition, which is relevant for kitchen utensils;
  • resistance to high temperatures;
  • porous structure that allows air to pass through;
  • The ability to hold a certain temperature for a long time;
  • does not change the taste of cooked food;
  • moisture resistance and the ability to withstand chemical attack.

Pots can have any style of design, and from the wide range of presented products you can choose the variant that will satisfy the taste of almost everyone. Clay products are better than ceramic ones in that they are more functional and do not block the red clay pores. Often used in everyday life, in the kitchen (used for cooking dishes in a variety of recipes on steam).

However, the traditional pottery has some shortcomings, due to which this material is inferior to other materials for the manufacture of dishes:

  • Brittleness and the need for care;
  • difficulty in the maintenance process, caused by the need for careful cleaning of the pot to avoid damage to the glazed coating;
  • special requirements in the operating environment: clay crockery should not be subjected to too rapid cooling or heating, it is also not recommended to cook in pots on an open fire;
  • Unglazed pots have the ability to strongly absorb moisture, which in conditions of low temperatures can provoke the formation of cracks on the walls;
  • property to absorb unpleasant odors, which is very difficult to remove, so that clay dishes are not suitable for storing strong smelling products;
  • the great weight of the product, which makes the process of transportation much more difficult.

A dishwasher makes housework much easier, saves time and water. Unfortunately, it is impossible to refuse completely to wash dishes by hand, because there are items for which the dishwasher is contraindicated.

Wood is best not subjected to aggressive cleaning with a lot of water.

Hand wash with a damp sponge and baking soda or dishwashing gel. Do not soak wooden dishes, otherwise they will swell and crack. Use table vinegar for disinfecting. After rinsing, wipe dry and leave outdoors.

Dishwasher use, which dishes must not be washed in it

The dishwasher is a big asset to the modern housewife’s kitchen. To ensure that the smart appliance copes with its assigned functions and works smoothly, it is worth observing the rules of operation prescribed by the manufacturer. The first thing that the user should clearly understand, what dishes should not be washed in the dishwasher, and what is suitable for cleaning with this device. If you load forbidden kitchen utensils into it, you can ruin the appliance.

What kind of ceramics tolerates automatic washing better?

The manufacturer must place a sign on the packaging, explaining whether the product can be washed in the dishwasher or not. If there is no such image, it is better not to give preference to such sets of dishes.

It is best to choose ceramics that have a layer of glaze. This kind of coating is a good protection against chemicals, water and heat. Thanks to it, pots and plates are more likely to last longer and won’t ruin your appliances. In addition, the protective layer prevents the porous clay from absorbing chemicals, so eating from such dishes is much safer, in addition, it will not begin to smell unpleasant.

It is better to choose such ceramic products, which were made not more than 15-20 years ago. Old cookware is generally not as strong.

Certain brands show better washability in the machine:

  • Nikko. Japanese faora ceramics, well protected by a durable layer of glaze.
  • Narumi. handmade ceramics that is resistant to high temperatures.
  • Royal Bone and Fine China. sturdy ceramic cookware that contains aluminum.

The right cookware is unlikely to break during automatic cleaning.

Sharp objects are contraindicated in the dishwasher. First, you can forget or just not know about the cutting objects, if the dirty dishes were not laid by you, and severely injured.

Second, such washing can ruin good appliances. Strong detergents with frequent use eventually dull the sharp edges of expensive knives. This is especially true for regular housewives, who don’t often bother to sharpen their dishes. Knife handles and carbon steel blades can get damaged in the dishwasher. rust over time.

Thirdly, carelessly placed knives can simply damage parts of the dishwasher, leading to breakage.

All this, of course, does not apply to common cutlery knives, but their steel inevitably tarnishes with time from frequent washing.

What dishes should not be washed in the dishwasher?

Almost all classic tableware can be washed in the dishwasher (stainless steel, glass, ceramic). These materials are not afraid of high temperatures or aggressive household chemicals.

If there are doubts about any dishes, you should pay attention to the icon that permits the use of the dishwasher.

The badge may not be present on all products. You need to remember what kind of dishes you definitely can’t wash in the dishwasher:

  • containing glue;
  • wooden;
  • Antique;
  • Expensive, ornamented with mother-of-pearl or gilding;
  • cast iron;
  • Aluminum;
  • of noble metals. silver and gold.


Above all, a strict restriction applies to wooden dishes. Prolonged exposure to water and high temperatures will cause the wood to warp. Chemicals are absorbed into the fibers and make the dishes unsafe for health.

Accidentally putting a wooden item in the dishwasher could be the end of it.

Plastic food containers, various lids, bowls, cups and glasses can be washed in the dishwasher. Dishware is not damaged if the condition is met:

Look for the mark on the bottom and judge the thickness of the walls. dishwashers usually specify another temperature at which the dishes can be washed. Do not load thin plastics into the machine which are easily deformed by pushing them with your fingers.

Tip. Clamp the plastic dishes with clamps so that they do not “wiggle” around during washing.

Remember that plastic is very lightweight. To prevent it from deforming from high temperatures, the top tray is used for loading. It is far enough away from the heating element.

Both faience and faience are dishwasher safe. You could say they’re made for each other. Dishware becomes bright and shiny after washing. Yellowing and tarnishing are gone. But there are some restrictions:

Faora patterned crockery without a glaze can be washed in the dishwasher using gentle chlorine-free detergents on a delicate setting.


There is a risk that luxurious crystal could fade in the dishwasher. Micro-scratches from abrasive particles in the detergent can remain on the walls. It is correct to wash crystal by hand at a temperature no higher than 40 degrees. If the machine has a gentle cycle, you can use it.

Noble and base metals

Using a dishwasher is much more convenient than washing dishes by hand. Especially one that has old plaque and hard-to-reach recesses. Don’t be tempted to wash items quickly and well.

Dishwashers can wash away the gilding and niello along with the dirt. Silverware will look like cheap aluminum.

This prohibition applies to base metals:

Cauldrons, duck pans, and pans made of these materials tend to darken and lose their luster when washed in the dishwasher. Cast iron will deteriorate.

You can wash stainless steel and melchior cookware without any glued parts or wooden handles.


A detailed list of what not to wash in the dishwasher can be found in the instruction booklet. Especially important to remember:

  • Small objects can fall through the bars of the basket. Properly wash them in a sealed container.
  • Teflon-coated pans and molds cannot be loaded into the dishwasher. Aggressive chemicals and heat are likely to destroy the top layer. There are exceptions. Some manufacturers allow machine washing of Teflon frying pans in a delicate mode. Study the icons on the bottom.
  • Clay pots can be washed in the dishwasher only if the clay is fired and glazed.

Taking care of earthenware dishes

Earthenware is an eco-friendly material and has served man for centuries. And today such dishes are very popular. Dishes cooked in clay pots have a unique taste and aroma. Clay dishes are indispensable for storing honey, jams, cereals, and milk in a clay jug can be stored without souring for up to three days. On hot days, drinks stay cold longer. The advantage of earthenware is that it is non-toxic and completely safe and does not react with the food, thus it does not change its taste. Even small children can be fed from earthenware plates and cups.

Clay dishes are used for cooking various dishes in stoves, ovens and microwaves. Thick-walled earthenware retains heat for a long time, the food in it as if languishes, preserving its useful substances. When cooking dishes in earthenware, you should always remember that, when taking the hot earthenware out of the oven or stove, you should not put it on the cold surface. Preferably you should put it on a wooden surface or a cutting board. It should cool gradually, so as to avoid micro cracks. If the products are glazed, then you should put such cookware in a minimally heated oven, and only then gradually heat it to the right temperature, because you can not allow sudden temperature drops. Do not recommend to put the product made of clay and the open fire, such contact is fraught with the appearance of cracks for earthenware. When using a clay teapot it is necessary to give the teapot hot water, before pouring the brew and pouring it with boiling water. Ceramics should be well dried after use. For preventive purposes, about once a month, you can bake the pans in the oven at the maximum temperature.

clay, pots, washed, dishwasher

It is better to wash earthenware immediately after use, in hot water with baking soda or mustard, or with a soap solution, then rinse with clean water. Aggressive substances should not be used. The porous surface of clay can trap chemicals which are then released into the food. Vinegar can be used for an extra thorough wash. Add a little white table vinegar to a bowl full of cold water and place it in a cold oven, gradually heating the oven until the water comes to a boil. After half an hour, turn off the oven, and let the water and dishes cool. Then wash the dishes with soap and rinse. Also, you can wash the clay pot the old-fashioned way with sand or ash. To avoid small scratches on the surface of the products, it is not recommended to use a hard sponge when washing. It is better to choose soft sponges.

Separately, it is worth mentioning that clay products with organic coatings should not be washed in the dishwasher categorically. It is better to let them soak in warm water for some time and then wash them with a soft sponge.

Any unglazed earthenware should preferably be wiped dry after washing. Once/twice a month, wipe the cookware in which the organic coating was used with a cloth with linseed oil. It is best to store such tableware uncovered. Otherwise there is a risk of an unpleasant smell from the inside of the dishes, in order to avoid this, open the dishes before storing them. This will keep mold and other bacteria away. Organic coated dishes should not be left in the open sun, otherwise the protective coating of milk and/or wax will burn out.

What can be washed in the washing machine under certain conditions

There is a group of cutlery that can be washed in the dishwasher at a certain temperature setting, choosing the right detergent and neighbourhood. For example:

Melchiorated appliances should not be placed in the chamber with other metal objects, as this causes them to oxidize and darken. If there are decorative elements of other materials on the handles. it is better to wash the set by hand. Also read the detergent instructions carefully to see if it is compatible with the melchior.

  • Phaor is a delicate, sensitive and expensive material. Japanese and Chinese faora manufacturers do not recommend machine washing, but experienced hostesses have invented a safe way to wash the table set in the washing machine:
  • Choose a temperature not higher than 55 degrees. a high temperature has a bad effect on the faora.
  • Do not use aggressive detergents.
  • Use only the top part of the basket for loading.
  • Cups, saucers and other items should not touch each other.
  • Don’t wash faor at the same time as other materials.
  • Do not use gold-plated or glazed decorations in the washer-dryer.

If you follow these points, you will easily get a clean and whole set.

  • Thermos. Dishwashing detergents, hot water, high pressure. can ruin a thermos by damaging the bulb. So if you choose the low temperature cycle, a delicate, liquid detergent, you can successfully wash a thermos, a thermos mug.
  • Children’s toys. Many moms use the dishwasher to wash and disinfect children’s toys. You can wash toys made of durable, quality plastic, without small, detachable parts, rubber, silicone. Not desirable to wash dolls with artificial hair. the hair after such a “shower” can not save.
  • Zepter brand.

Zepter cookware is popular, quality cookware with high technology. Made of durable alloys and heat-resistant glass that can withstand dishwashing. But some technical elements (such as the thermal controller on the lid) can be damaged during washing. Therefore, such parts must be unscrewed before loading into the hopper.

  • Teflon pans, sauté pans, saucepans. If we’re talking about the original Teflon brand, the manufacturer gives permission for automated care of Teflon products. But quite often, salespeople call any nonstick coating Teflon. So make sure you read the instructions, look for the permissive and prohibitive labels before you load the dishes. If there is a “washable” sign, feel free to load and run the cycle. The symbols on the dishes will help you decide on the correct use, care, storage.
  • Knives. If your dishwasher has a special compartment for knives, you can wash them without any problems. In the opposite case. the sharp blades damage the metal of the grid, blunt, wooden handles are spoiled.
  • Trays can be washed in the lower compartment, if it is the right size, you must first remove any burnt food residues, grease, so as not to clog the pumps.
  • Cast iron, cast iron grates. Cast iron products deteriorate from aggressive detergents, high temperatures, prolonged exposure to water. Subject the cast iron to this test as a last resort, choosing the shortest mode, low water temperature, no detergent. This also applies to grill racks if they are not made of aluminum. Aluminum deteriorates in the machine.
  • Filter jug. Pitcher “Barrier”, “Aquaphor”, etc. can be washed in a washing machine at a temperature no higher than 40 degrees.
  • Hood filter. The choice of cleaning method depends on the material from which the hood mesh is made. If it is aluminum or aluminum alloy. choose manual care, otherwise the filter will blacken, deform.
  • Refrigerator shelves. Dense plastic shelves can be refreshed at low temperatures, without abrasive detergents. otherwise the material will be scratched.
  • Plastic containers. if there is a sign permitting this method.
