The peusaect wash in two variants

Everyone knows that disinfection is a set of measures that aim to destroy micro organisms: bacteria, viruses, fungi, bacilli. Everyone is intolerant of these harmful microbes, but cleanliness is especially important for infants, allergic people and people with skin diseases and infectious diseases.

Our clothes lose their freshness in many ways because organic dirt breeds germs and bacteria, but getting rid of them makes the laundry fresh and comfortable. It turns out that disinfecting is a very useful thing!

And it has its own rules – let’s divide them into two groups: physical exposure to high temperatures and chemical treatment with special agents .

Boiling – time to kill?

European housewives have long since given up on cupping, because it’s so time-consuming and energy-consuming. Laundry machine and laundry detergent manufacturers say with one voice that you don’t need to boil it, because you can get great washing results at lower temperatures. But when one of my housemates fell ill, the doctor’s verdict was simple: “linen and towels should be boiled!”

Microorganisms killed by boiling – some die instantly like dysentery bacillus , others take time, for example, hepatitis viruses B and C will last about an hour, and tetanus spores – up to three hours.

But not all things take kindly to high temperatures, as the signs on the labels remind us. Textiles wear out quicker, colors lose juicy shades, rubber bands deform, clasps get spoiled by boiling, etc. d.

For most American housewives, boiling is still a necessary attribute of hand washing. But for us it is important that at the same time as removing dirt and many stains, the fabric is reliably sterilized.

Automatic washing machines have the highest available temperature – 90-95 ° C. No higher temperature: because the active process with the formation of bubbling bubbles and the release of large amounts of steam is unlikely to be to the liking of electronics.

Why heat more??

Not only frugal housewives, but some washing-machine manufacturers think so. For example, Whirlpool has created a special program called Antibacterial, where the water is heated to 80°C. This level of temperature is maintained precisely for 15 minutes, which, according to the developers, is enough for ordinary situations.

Miele washing machines have a Hygiene-Cotton programme, with a working temperature of 60°C for one hour – as we remember, this is the pasteurization temperature, which kills active micro-organisms and kills dust mites. The machine has special programs for washing pillows at 60-90°C and delicate fabrics 30-95°C .

You can use water heated to 60 or 80 ° C in other machines, but you should keep in mind that the water is brought to the desired temperature only at the beginning of the cycle, and during the washing its gradual cooling takes place for this reason it is important how “holds” the heat material in the tank of the machine .

Let’s rejoice at !

Things can also be disinfected by steam, which is especially convenient directly in the washing machine.

The tiny steam particles penetrate deep into the fibers of the fabric and the steam, like a gas, has a large surface area: at 100 °C it takes up 1,600 times the volume of water at 25 °C. It means that not just part of the garment say, dipped in water , but the whole thing is treated. That’s why things are disinfected both on the surface and inside the hair.

The water in washing machines is heated by heating elements, and the steam generator fills the drum with steam.

The steam circulates freely inside the washing cycle, comes into contact with the fabric and kills micro-organisms. Hot water at 60 degrees or more can be very useful in disinfecting the steam.

In the first case, pasteurization will occur in the solution, and in the cooler water, the powder enzymes will be able to show their activity. These enzymes protein compounds are able to dissolve some allergens mites, animal hair, pollen .

Steam for disinfection can be used separately, in modes like “Freshen”, where water is not added at all.

Steam washing machines are available from only a few manufacturers – LG, Daewoo, Whirlpool and Kuppersbusch, but so far it’s an innovation. I think that over time there will be more of them just like, for example, the steam cookers in different manufacturers’ ranges .

And the fact that steam is quite effective as a disinfectant is confirmed by research – for example, LG have had their steam washing machines certified by the British Allergy Foundation BAF .

A tip for the road

Disinfection in washing machines has an important advantage: the inner parts of the device are also treated, which prevents repopulation of flora from previously laundered items, stops the growth of bacteria and fungi eg mold on the machine parts.

By the way, mold in the washer is a commonplace and constant headache for hosts. It occurs most often in powder cuvettes especially after continuous use of viscous gels , tubes and cuffs.

Not only does this phenomenon spoil the external or rather internal appearance of the appliance, mold produces an unpleasant smell and is simply a health hazard.

In addition to the disinfection methods listed in the article, the following method can also help: Use a cloth soaked in soda solution to scrub the mold from the surface, and then Dollars the spot with table vinegar.

Another option is to use citric acid, as in scale removal. You need to add 3 to 5 tablespoons of acid in the hot water wash mode, or by turning on a separate rinse cycle.

There are also ready-made remedies: Doctor Tan Antibacterial, Bisol, From Mildew, sprays Lion, Astonish Mould & Mildew Remover, Delu and others.

If it’s dry, it’s clean?

In the battle for microbiological purity dryers can also help. In the basic programs for cotton, the laundry is dried at an air temperature of about 60-70 ° C in the disinfection chambers it is of course higher: 80-105 ° C , and the items are intensively treated by the moving streams of hot air from all sides.

Of course, hot ironing is a very important part of the disinfecting process.

Dry cleaner at home

Physical methods of home disinfection are within the reach of every housewife. Of the latter, the easiest is the addition of bleach when washing.

We have repeatedly written in detail about these compounds that help us actively fight stains on things. Let me remind you that the removal of dirt with bleaching agents is due to the oxidation reaction. In oxygen-containing bleachers as the name implies , the working substance sodium perborate, sodium percarborate, potassium persulfate or sodium perphosphate , interacting in solution, releases oxygen.

Chlorine-containing solutions work like this: hydrochloric acid disintegrates to form atomic oxygen. Thus, an oxidizing reaction always accompanies the bleaching process, and as we know, oxidizing agents have a bactericidal, fungicidal t.e. antifungal , virulicidal anti-viral effects, and a strong antifungal anti-infective effect.

Not without reason chlorine is one of the most accessible and, probably, the most popular disinfectants in hospitals, swimming pools, it is used for drinking water treatment. Chlorine products are much more active against pathogenic flora than peroxide bleach, and chlorine works well at normal room temperature and does not need to be heated to start the oxidation process. However, chlorine is known to have an unpleasant odor, destroys fabrics, quickly deprives dyes of color, in addition, it is a poison. It is not recommended to use bleach in the home without a special need.

Most often bleach such as “Belizna” or “Ace” is used for soaking the laundry in a basin, but they can also be added to the washing machine, in the main wash cuvette they are poured as the machine is filled with water . But chlorine interferes with the enzymes in the powder. It can therefore be used at the end of the wash or in the first rinse phase.

Oxygen-containing bleaches are used in almost all detergents, but they cannot “widespread” disinfect. Although their whitening agents can help this process if the water temperature during washing exceeds 60°C. For reliable removal of microorganisms the concentration of the active substance must be several times higher, for comparison: washing powder contains from 5 to 15% of sodium perborate, while a special detergent contains 45.5%. And, therefore, it is worth adding a “horse dose” of bleach preferably non-surfactant, so as not to increase the amount of foam .

It is better to silver than to boil!

The noble metal was the basis for several unusual innovations in machine washing. Thus, Samsung developed the Silver Nano technology. Its point is to get silver ions into the detergent solution as well as into the rinse water. These ions are formed by passing an electric current through a pair of silver electrodes immersed in water. Then the water saturated with silver ions enters the tank of the machine and takes part in every step of the washing process.

The ions, being positively charged, are attracted to larger microorganisms and, penetrating through the shell, destroy them. The Silver Nano function is activated by the user by pressing a button on the control panel.

Daewoo washing machines have silver in every washing cycle throughout the life of the machine, and all this is due to a special coating: tiny silver particles are added to the basic elements of the washing machine. This ensures cleanliness and protects the laundry from pathogenic bacteria, and inhibits the growth of harmful microorganisms and fungi of all kinds.

Water chemistry

In the washing machine Haier Washer H20 B, which is not yet sold in our country, the disinfection is provided by ordinary water, more precisely, its ions that are formed in the process of electrolysis. Cations are positively charged particles H+ that become sterilizing agents that destroy microorganisms at an ordinary temperature, without additional chemical support. And the anions OH- fight the dirt on the fabric.
