Why don’t you wash your knives in the dishwasher

What Dishwashers are Dishwashers forbidden??

Buying a dishwasher can be a problem for those who don’t know what they can and cannot wash in a dishwasher. Of course, it’s best to change all your dishes to be dishwasher-safe, and then you won’t have any problems.

But if there is no such a possibility, then, one way or another, some items will still have to be washed by hand. About what you can not put in the dishwasher and will go further narration.

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 section for washing knives. When washed with other dishes, the knife not only blunts but also scratches neighboring items.

High water temperature and pressure

Another reason is excessive water pressure. As a rule, there is no prohibition against washing sharp kitchen utensils. But it’s better to wash the knives separately in the sink under running water. Also, knife blades become deformed due to elevated temperatures. In addition, the knife is no longer sharp and corrosion eventually forms on the surface. In addition to the blade, washing in a household appliance also negatively affects the knife handle. The wooden handle will swell and crack in hot water. Plastic deforms already after 12 washes. Housewives become frustrated if an expensive set of knives is ruined.

Using detergents with abrasive compositions

Special aluminum rivets are used to join the handle and blade. When washed in a household appliance with detergents, they stop bonding. Substances in detergents negatively affect the rivets of knives.

Can I Wash Knives in the Dishwasher?

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

After the dishwasher the meat grinder is blackened: what to do?

I train appliance repairmen! Salary from 80,000 !

Almost all kitchen utensils can be washed in the dishwasher. It is not recommended to load in it unless the products from plastic and wood. And what about the meat grinder. is it possible to wash this useful thing in the dishwasher?? If pots, bowls and other metal dishes can be washed in the dishwasher, then why the meat grinder becomes black after being processed in it??

The causes of damage to metal knives

Most housewives use kitchen knives with blades made of steel. How can the dishwasher harm such a cooking tool?

No compartment for sharp objects

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

Can I wash my Knifes in the Dishwasher?

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 water temperature

Another reason why the blade quickly becomes blunt from washing in the dishwasher is due to too much water pressure in the chamber. Although the instructions do not generally prohibit washing appliances with blades in the dishwasher, it is better to refrain from doing so. This way you get a much longer life.

The thin blade of a kitchen knife can become deformed from exposure to hot water. The metal quickly becomes unusable.

Especially expensive professional dishwashers are a shame.

Aggressive detergents

Aluminum rivets are often used to fasten the handle of a kitchen knife. If they are exposed to an alkaline detergent solution for a long time, they lose their oxide film which protects them from oxidation. After a few washes, the rivets may no longer hold the handle and blade together at all.

Tips for proper care

For the knives to last a long time, it is worth keeping in mind the following rules for use and care:

  • Use a separate tool for each application. Knife for cutting meat fillets can be spoiled by cutting the bones. And a butter knife will be permanently ruined by cutting fish.
  • Store the knife in a box, wrapped in paper or cardboard. So it will absorb the excess water, and the blade will not be damaged by other appliances.
  • It is better to use wooden or plastic cutting boards. Ceramic, glass, marble boards wear down and deteriorate the blade very quickly. The best choice is a flattened paper or soft cardboard.
  • It’s easy and convenient to store sharp utensils on a magnetic holder that can be mounted right on the kitchen wall.

So, it’s better not to wash neither expensive profs nor cheap Chinese knives in the dishwasher. Brutal environment in the car will soon spoil any blade and handle. It’s easier, safer, and sharper to simply rinse the knife, wipe it down with a dry rag, and put it away until later use.

A stainless steel cutting board. Does it dull knives? Is it worth buying? Can I Wash Knives in the Dishwasher? Let’s get this straight.

People who are familiar with my “creativity” on Muskie, probably think that I’m out of my mind, and as a result I bought myself an “iron” cutting board. To blunt your knives against it and then sharpen them in misery. But it’s not all that bad, really. As it often happens, the Комментарии и мнения владельцев under my big last year review on cutting boards incited me to buy such a board. I bought it just for the sake of the experiment. Let’s see what happened. So, here it is. In the Комментарии и мнения владельцев I started writing about the marble and stainless steel cutting boards. And like these boards do not stain knives and in general they are very good. Marble board I certainly have not seen on sale, but the boards of stainless steel first began to appear on Taobao, and after a while and Ali. I figured why not give it a try, so I ordered a medium size board. And here it is. Arrived well, no damage. It was packed in shrink wrap.

The board is shrink-wrapped. The back is also covered in shipping film. We sell small sheets of stainless steel in our construction store with such a film. Peeling the board of all unnecessary things

There’s an engraving with steel grade on it, I guess

Let’s start by washing the board. Water on it gathers in droplets (does not get wet). The board is pretty marky and leaves traces from your fingers or a damp towel

It begs the question. What to do next with this board? And how to test it? The way I see it. You need to take some other board as a counterbalance and cut on them one by one, revealing the negative moments in the operation. For comparison, I chose the most used polypropylene board in my kitchen, bought on Tao and described in the board review. And yes, this very board, one of our colleagues from Moosek “trashed” in half a year just in the trash)))) And wrote a review about it.

Now I need the knives. And preferably they should have the same characteristics. To make the tests equal. This is how I solved this problem

These are three identical knives Tramontina Profissional Master 6″ 24620/086. They are brand new, have never cut anything with them, and were purchased specifically for the review.

Newspaper cut. But I wouldn’t say these are any super sharp knives out of the box. I’ve seen sharper ones. But in principle, for a kitchen knife, this is a good sharpening. The question is why there are three knives? I’ll explain. One knife I will cut on a polypropylene board. And I’ll mark it on the handle with the letter P. The second knife, respectively, on the metal board. And the letter on the handle will be H. The third knife is unmarked and will simply be washed in the dishwasher. Twenty times.

What does that have to do with the dishwasher?? It has nothing to do with the review. It’s just that underneath all my reviews of knives, there’s a discussion about whether you can wash knives in the washer and dryer. I believe that if the handle of the knife is not wooden and the knife is not made of hard steel, then you can wash it. But I don’t understand why. Why do people even wash their knives in the washer and dryer? What do you do with them and what do you smear them in that is necessary. I don’t know about people, but I run the machine every other day. Sometimes every day, but that’s mostly on the weekends. And okay, plates. I have a lot of them the same and they can gradually fill the washing machine. But knives aren’t plates. You need them all the time. How do I get them in the washer and dryer? And knives don’t get dirty, it takes three seconds to wash them. This is not a plate in buckwheat and sauce. So I don’t wash my knives in the washer and dryer. But someone’s washing. And someone does not wash and argues that knives in an aggressive environment in the washing machine lose sharpening. That’s a pretty interesting version, and that’s what I decided to test.

What do I even think about all of this tentatively. I think a metal board will dull knives faster than a polypropylene board. It’s hard to change my mind. Yes the stainless is soft and the bluntness will probably not be very fast, but because of this the board is clearly quickly covered with a grid of scratches. Let’s go

Potatoes. I need to cut it into slices. It’s kind of like a Mac’s rustic potato. I’ll cut my potatoes one at a time. One on one board, one on the other board. And so on. After the first potato, there were knife marks on the stainless steel board

What I can tell you from the feel of it. I began to feel pretty quickly that the knife after the metal board is already blunt. It’s just that the potatoes started to cut with such a crispy sound and you could feel the resistance of the knife. On the polypropylene board, on the other hand, the potatoes cut “like a knife through butter.”. As if it weren’t potatoes, but ripe avocados. Now the onion

I cut the onions in half and divided them equally between the boards

Once again, the second knife feels a little dull. So basically the dish I was making is done

Meanwhile, the third knife went in the dishwasher. I won’t even take it out of there. Only I will be placed differently when washing

I’m going to wash it in heavy soiling mode plus drying

And here I did not feel like a dull knife. And this is a really dull knife. It was very dull. I even thought I’d put up a picture for clarity

As you can see, the result is there. And I can already see visually that the knife is blunt at this stage. The cutting edge on the blade started to shine. And this is a clear sign of a blunted knife. I finally got the salad done

That would be the end of the review, if not for the third knife, which washes in the dishwasher. And he will be washing there for a very long time. And to reduce this time, I decided to run it every day. And after twenty washes, you can see what has become of the knives

Let’s get some newspaper. The first will be the knife used to cut the polypropylene board

I can’t say it’s as sharp as it was out of the box, but I got the newspaper cut up somehow. The knife that was used to cut through the metal board couldn’t cut the newspaper at all. The knife from the dishwasher shredded newspaper with no problem

Twenty washes in a row had no effect on the sharpening of this knife. So now I can assert that the PM does not dull the knives on a long distance. In any case, if it stalls, it is not very much, and you don’t have to take it into account at all. You will blunt on the board much faster. To evaluate the sharpness of the knives again, I took a thicker paper than a newspaper. The knife from the polypropylene board

I was able to make a couple of cuts, and that’s only because there was a spot on the knife blade, near the handle, that wasn’t blunted. Otherwise, the knife just crumpled or tore the paper.

The bottom line is. No stainless steel board, much less marble, will keep your knives sharp. Of course you can say that it’s bad Chinese stainless steel, but there are good boards and they don’t blunt knives. But. It’s all bullshit, if you ask me. Metal will get dull fast anyway. Unless it’s a lead board, of course. But I don’t think you’d want that in your kitchen. Yeah, restaurants have a practice of cutting food on stainless steel. Especially Asian food. Like tepanyaki dishes. Where the food is cut in front of you on a hot stainless steel surface. Or even a banal shawarma. When it is cooked, the meat is also shredded on a metal surface. But, there and the knives are not so sharpened and sharpen them every day and during the day. I sharpen my knives at home once a year, or even less. The rest of the time I straighten my knives on leather with GOI paste. That’s what I’m getting at. Metal cutting board is bullshit. And yes, another observation. My wife remarks. When you chop on this board, onions for example, the kitchen is filled with annoying noises. The knife makes a loud “clank” on the surface of the board every time. And it’s just not very nice to listen to. It’s certainly better than a glass board (and some people use them, too), but by and large, I don’t recommend it. Save your knives if you care about them.

Rule of thumb. choose the right wash mode

The standard dishwasher cycle includes prewashing (rinsing off food residue with cold water), washing (directly washing with hot water and detergent), rinsing (rinsing off detergent) and drying.

There are also such programs as intensive washing (very high temperature. up to 75 degrees), program for fragile dishes (water tº. 30 to 40 degrees), quick washing (when you need to rinse dishes after liquid foods and right after the meal) and others.

The program you choose (wash time and temperature) must be consistent with the type of dishes and the degree of dirt.

In addition, mid- and high-end dishwashers have a “pre-soak” function. But it’s much easier and more economical to remove the dried-on food residue by hand before loading plates into the machine. Same with “burned” pots and pans.
