Microwave sterilization of cans

Procurement of conservation is a rather laborious process. In addition, it takes a lot of time not only to prepare blanks, but also to prepare containers. To speed up this process, many different ways have been invented. Some sterilize jars in the oven, others in a multicooker. But the fastest method is to sterilize the cans in the microwave. In this article, we will talk in detail about how to do it correctly.

Why sterilize jars

Sterilization of cans and lids is an essential step in the canning process. Without it, all efforts can go down the drain. It is sterilization that guarantees the safety of the workpieces for a long time. Why can't you just wash the containers well? Even with very thorough washing, it is impossible to get rid of all microorganisms. They can be completely harmless to human health and life. But over time, the waste products of such microorganisms can be very dangerous.

Accumulating in closed banks, they become a real poison for humans. It can be difficult to notice the presence of such bacteria, as the blank may appear to be quite usable at first sight. Surely everyone has heard such a terrible word as botulism. This infection can be fatal. And the source of this toxin is precisely the preservation, which has been improperly stored.

Therefore, glass containers for blanks must be sterilized. This is the only way to protect yourself and your family from harmful microorganisms. You can read about how to do it correctly and quickly below. In addition, you can see a photo of this process, as well as a video.

How is sterilization of cans in the microwave

First of all, you need to thoroughly wash each jar. Don't skip this step, even if the cans look clean. It is recommended to use regular baking soda. Then the containers are dried, leaving upside down on a towel.

Attention! Be sure to check if there is any damage to the banks. Such dishes can burst during sterilization.

It can be difficult to find time for procurement, as it usually takes a lot of time. Housewives have to prepare fruits and vegetables for hours. So you also need to boil each jar. But I really want to prepare as many goodies as possible for the winter. In this case, microwave sterilization is a real salvation.

In addition to being time-consuming, sterilization also creates some inconvenience that makes the whole process unbearable. In the beginning, all the jars are boiled in water for a long time, which is why the kitchen is filled with steam. Then they must be carefully removed from the pan so as not to burn your fingers (which often fails). And sterilizing cans over a pot of steam is even more difficult.

Previously, many doubted that microwave sterilization of workpieces was safe. But over time, they became convinced of the practicality and harmlessness of this method. The main thing is not to put containers with lids in the microwave.

Sterilization of cans in a microwave oven is carried out in several ways:

  • without water;
  • with water;
  • immediately with the blank.

Sterilizing water cans

Most often, housewives sterilize jars in the microwave with the addition of water, thus, the same effect is obtained as after sterilization over steam. It happens as follows:

  1. The first thing to do is to wash the jars with the addition of soda and pour a small amount of water into them. The liquid should fill the jar by 2–3 cm. For these purposes, it is better to take filtered water, since ordinary tap water can leave a residue.
  2. The containers can now be placed in the microwave. Never cover the jars with lids.
  3. We put the microwave on maximum power.
  4. How many containers do you need to sterilize? We set a timer for 2 or 3 minutes, depending on the size of the can. Typically, this method is used to sterilize half-liter and liter containers. However, there are ovens that can easily fit a three-liter jar. In this case, sterilization will take longer, at least 5 minutes. Since microwaves can be of different power, it may take more or less time. In order not to be mistaken, you need to observe the water. After it boils, the jars are left in the oven for another couple of minutes and turned off.
  5. Use oven mitts or dry tea towels to remove the container from the microwave. The main thing is that the fabric is not wet. Because of this, a sharp jump in temperature will occur and the jar may simply burst. In order not to risk it, take out the container with both hands, and not by the neck.
  6. If water remains in the jar, then it must be poured out, after which the container is immediately filled with a blank. While you are rolling up one can, you can lay the rest upside down on the towel. Each subsequent can is turned over just before filling it with the finished product. Thus, the temperature will not drop as quickly.

Important! Remember that hot cans can only be filled with hot contents, and cold ones, respectively, with cold ones.

Usually, about 5 half-liter jars are placed in a microwave oven. If you need a larger container, for example, a three-liter can, then you can lay it on its side. In this case, be sure to put a cotton towel under it and pour some water inside the container.

Sterilization without water

If you need completely dry containers, then you can use the following method. Banks must be washed and dried on a towel. After they are completely dry, place the containers in the oven. Next to them, you must put a glass of water (2/3 full). If you pour a full glass of liquid, then during the boil it will pour over the edges.

Next, turn on the microwave and wait until the water has completely boiled away. Usually 5 minutes is enough for this. Then the cans are removed from the microwave, as in the previous method. Hot containers are immediately filled with jam or salad.

The advantages of this method

Although this method has some disadvantages, advantages prevail. It is not for nothing that many housewives have been using it for a long time. The main benefits include the following:

  1. It is quick and very convenient compared to the classic sterilization method.
  2. Several cans are placed in the microwave at once, due to which the preservation process is faster.
  3. The microwave does not increase the humidity and temperature in the room.

Attention! In addition to containers for blanks, bottles for children can be sterilized in the microwave.

You just need to put the disassembled bottle in any container with water. Then they turn on the microwave and wait about 7 minutes.


Experienced housewives have long been using microwave ovens for sterilizing cans with blanks. It is very easy to do this, and, most importantly, quickly. We are sure that the methods described above will facilitate your work, and you can prepare even more conservation for the winter.
