Can I wash knives in the dishwasher?

What dishes are exposed to in the dishwasher

Why some dishes can be put in the machine without any problems, while the other dishes should not even be tried in the dishwasher? The fact is that inside the washing chamber there are certain conditions that affect the dishwashing material. These conditions include:

  • Heat the zucchini mixture over high heat;
  • Strong chemicals;
  • Being in contact with water for a long time;
  • forced drying with hot air.

Today, dishes are made from a variety of materials, including: glass, faora, iron, silver, aluminum, melchior, plastic, cast iron, crystal, earthenware, ceramics, Teflon and others. But even cookware made of aluminum reacts differently to hot water and detergents. Let’s find out what you shouldn’t put in the dishwasher.

Alumina products have no place in the dishwasher

Aluminum cookware is the number 1 dishwasher safe. Aluminum is a metal that reacts with many substances, including water, if certain conditions are met. Under the influence of detergents and high temperatures, aluminum products acquire a dark grayish patina, and this patina smears, leaving traces on the hands.

Dozens of people have already ruined their dishes in the dishwasher through ignorance:

  • aluminium parts from a meat grinder;
  • garlic grinders;
  • spoons;
  • bowls;
  • ladles;
  • trays;
  • pans;
  • saucepans.

For your information! Aluminum cookware is better to replace in general, it is harmful to the human body. At least, you should use such utensils as little as possible.

Some aluminum cookware is already darker after one wash, some only after several washes. That is why there are those who wash everything in a row and say that nothing will happen. If you spoil your aluminum cookware, then in this article Why You Can’t Wash Aluminum Cookware, you will find tips on how to clean it.

Kitchen knives in the dishwasher? Can or can’t? Recommendations!

Today we’re going to talk about kitchen knives and the dishwasher. In general, there are a number of opinions on the subject of washing kitchen knives and, more often than not, these opinions are somewhat divergent. On one side there are outspoken opponents of washing kitchen knives in a dishwasher, like it’s barbaric, but on the other side there is the opposite point of view. All kitchen knives can be safely washed in the dishwasher and there’s no problem. There are, of course, nuances. So let’s find out.

This article is based on many years of personal experience in sharpening all kinds of kitchen knives and from observations there is a clear picture that I want to share with you. I will demonstrate all this including personal experience. And yet I would like to start exactly from the point of view of a conventional manufacturer. Or rather his official position. Of course, there are different manufacturers. Some are bigger, some are smaller, and so on. But more often than not, the recommendation will be plus or minus the following. do not wash knives in the dishwasher. This recommendation is unlikely to be categorical at this time, but it is quite specific. Kitchen knives after work should be rinsed in warm water, do not use abrasive detergents, then wiped dry and put in a proper stand. And, it would seem, this is the end of the article, the manufacturer has said its word and they know better. And in general, you know. all right. And one more important note, if the manufacturer has prohibited the use of a dishwasher, and you used it, you can be deprived of warranty. But this will need to prove, there is a law on the protection of consumer rights and it is always a good idea to remember that.

In my opinion, there can be many reasons why manufacturers do not recommend using a dishwasher. We can’t know everything even in theory, but let’s try to understand the main ones and base our recommendations on them. Which ones you can wash in the dishwasher and which ones you shouldn’t?

And now let’s go into a little bit more detail. The first reason manufacturers don’t recommend washing knives in the dishwasher is trivial. Despite the fact that the vast majority of steels in modern kitchen knives are called stainless, in fact stainless steels are actually used on kitchen utensils, for example, such steels are used to make pans. Really stainless steel is very poorly thermo-mechanically treated. Simply put, it’s hard to harden, and that’s why such steels aren’t usually used on knives. Steels that are used on knives are only conventionally stainless. Such steels resist corrosion and here the degree of this resistance is different for everybody. The overall resistance to rust is determined not only by the steel itself, but also by the production cycle, the nuances of knife manufacturing and, among other things, the coating of the blade. For example, classic damascus on Japanese knives is, first of all, corrosion protection, and then everything else. And, of course, hot water together with a powerful cleaner increases the chances of corrosion. But this kind of damage can already be a reason for a complaint. That’s why manufacturers don’t hasten to recommend you a dishwasher for their knives.

Based on the steel on the knife blades, the first recommendation is as follows: knives made in Europe are 99 percent made of steel that has no problem with the dishwasher. Japanese knives made of vg-10 steel are just as good at resisting corrosion as knives made of g2 steel. In theory, Japanese steels can and will rust with negligence, but in practice there is plenty of common sense. But for Japanese zdp-189, a dishwasher would probably be a problem. This is a very serious steel with incredible characteristics, but far from the most comfortable in normal handling.

Also a general recommendation for steel: if the blade or the description says carbon steel and does not say stainless, such knives should not be washed in the dishwasher. Note: different dishwashers have different modes, but most often there are three. is an intensive mode at a temperature around 70 degrees. it’s a light or rinse mode at a temperature around forty-five degrees and a normal or eco mode around 55 degrees. That’s the one in question and that’s the mode with a temperature around 55 degrees Celsius that I recommend using for knives.

The second reason why knife manufacturers do not recommend using dishwashers is a little more complicated. In the twenty-first century, a satisfied customer should come again, bring his friends, girlfriends and mother. Hence, the manufacturer is very important next point. it is the external perception, it is the first impression and in general all that forms the image. Of course, comfort is also important, but comfort is a matter of habit, isn’t it? I repeat, there are different manufacturers. approaches are different. Everything can be very different, but the essence is somewhere near. In such a cut, a knife that is washed in the dishwasher has a great risk of damaging the cutting edge by hitting the pot or plate. There may be some minor rust spots or streaks on the blade. As a result, the external perception and the impression of the knife will be blurred and the user is likely to contact the producer of the knife.

In the end it is important that common sense and accuracy solves all issues. There is now an abundance of racks, baskets and other systems that allow you to conveniently and safely place spoons and forks, lids, knives in the dishwasher. This also excludes damage to the cutting edge, it excludes cuts, adds comfort.

The third reason: the most important thing is the handle. Roughly speaking, it is the handle of the kitchen knife that will divide all kitchen knives into those that can be washed in the dishwasher and those that should not. There are many kinds of handles, they differ in type of blade mounting, type of material used, how the bolster is mounted and so on.

There is only one almost 100 percent reason not to wash knives in the dishwasher. it is the presence of wood on the handle of the knife. Natural wood is a great material, no doubt about it, and there are species that are very easy to tolerate high humidity, but combined with the hard and precise fit of the knife handle, the wood becomes unfit for the dishwasher. Such a knife is likely to lose not only its aesthetics, but also its performance characteristics over time.

The all-metal handle of a kitchen knife is almost always a guarantee of complete dishwasher washability. Almost always, because there are roughly three types, first, it’s an all-metal handle made of a single blank of steel without any solder or glue, and second, it’s a handle made of two parts connected by soldering. And finally, the same handle, but with glued joints. What exactly is on your knife you can ask the manufacturer or your dealer. Here are the first two types withstand the dishwasher without question, the 3 with the glued connection differently.

Indeed, some kitchen knives are highly undesirable to wash in the dishwasher. And it’s important to know this because the comfort of use is not less important than the quality and durability of the cut. On the other hand, a huge number of knives, with proper care and common sense, will safely wash in the dishwasher for years, greatly simplifying kitchen life.

According to experts, you should not put knives in the dishwasher. There are many reasons for this prohibition.

No special compartment for sharp objects

Most dishwashers don’t have a knife-washing compartment. When washed with other dishes, the knife not only gets blunt, but also scratches neighboring objects.

High water temperature and pressure

Another reason is the high water pressure. As a rule, there is no prohibition against washing sharp kitchen utensils. But it is better to wash knives separately in the sink under running water. Also, knife blades become deformed due to heat. In addition, the knife will no longer be sharp and corrosion will eventually form on the surface. In addition to the blade, washing in a household appliance also negatively affects the handle of the knife. The wooden handle will swell and crack in hot water. Plastic ones deform after as little as 12 washes. Housewives get upset if an expensive knife set goes bad.

Use of abrasive detergents

Special aluminum rivets are used in manufacturing to fasten the handle and blade together. When washing in a household appliance with detergents, they cease to bind. Substances in the products have a negative effect on knife rivets.

Can I wash knives in the dishwasher?

Today’s housewives are used to washing everything in the dishwasher. As a result, some crockery as well as cutlery fails prematurely. This is because the hostesses do not take into account the restrictions on the use of the washing machine, which we will partly touch, considering this topic. This time we are interested in the question: can we wash knives in the dishwasher?? Are there any restrictions on knives or not?? Let’s find out.

A strainer and garlic press

The dishwasher can’t handle these kitchen accessories.

Both the strainer and garlic press are the type of kitchen accessories that are very difficult to clean with your own hands. We have to stock up not only with toothpicks, but also with patience. Still, it’s better to spend an extra 10 minutes cleaning them than shifting the job to the dishwasher. The thing is that even strong jets of water are not able to push the garlic particles out, so strongly they get stuck in the sieve.

As for the sieve, it is also not easy to wash, because in contact with water, the flour becomes one solid sticky mass. As a result, it gets clogged in small holes and you have to spend at least half an hour to wash the sieve.

Causes of damage to metal knives

Most housewives use kitchen knives with blades made of steel. How can the dishwasher damage such a chef’s tool?

No compartment for sharp objects

Many dishwashers do not have a special compartment for washing knives. If they come into contact with other metal utensils and phrases, they can not only get damaged and blunted, but also leave scratches on neighboring items.

Some dishwashers have such a compartment. It is most often located at the top of the machine, where no hot water enters.

High-pressure and high-temperature water

Another reason the blade becomes blunt quickly after washing in the dishwasher is that the water pressure in the chamber is too high. And although, according to the instructions, most often it is not forbidden to wash appliances with blades in the dishwasher, it is better to refuse to do so. This way, they last much longer.

The thin blade of a kitchen knife can become deformed by the hot water. Metal quickly becomes unusable.

It’s especially a shame to ruin high-end professional appliances in the dishwasher.

Aggressive detergents

To fasten the handle of a kitchen knife are often used rivets made of aluminum. They lose the oxide film that protects them from oxidation when exposed to an alkaline cleaning solution for a long time. After a few washes, the rivets may completely stop binding the handle and blade.

Tips for good care

To ensure a long life for your knives, it is worth remembering the following rules for use and care:

  • Use a separate appliance for each purpose. A filet cutter can be ruined by cutting through bones. A butter knife will be permanently ruined by cutting fish.
  • Store the knife in a box, but wrap it in paper or cardboard. That way it will absorb excess moisture, and the blade will not be damaged by other devices.
  • It’s best to use wooden and plastic cutting boards. Ceramic, glass, marble boards wear out and damage the blade very quickly. It’s ideal if you use thick paper or soft cardboard.
  • It’s simple and practical to store sharp instruments on a magnetic holder that can be mounted directly on the kitchen wall.
