Descale washing machine

Descale washing machine

Over time, lime deposits form in washing machines and become a problem in the long term can. They use the heating elements and ensure a higher power consumption. Highly calcified devices are more likely to break down than the machines that often receive the necessary care. It is therefore necessary to descale the machine regularly. But when asked how a washing machine is decalcified correctly, the ghosts divorced. In today's guide, you'll learn how often you should clear the washing machine of lime, which decalcifier is really suitable and which home remedies are suitable for descaling.

Why does the washing machine have to be descaled?

There are many reasons for that talk about regularly cleaning the washing machine with a descaler:

  • Calcified heating elements consume more electricity
  • A five-millimeter lime layer is enough to increase the amount of electricity in the wash cycle by 30 percent
  • Defective calcifications often cause defects
  • In a calcified washing machine, washing is often not really clean

In order to prevent technical problems and save energy, it is necessary to descale the washing machine at regular intervals.

How often should you descale the washing machine?

How often the washing machine is to be descaled depends primarily on the degree of hardness of the water. Depending on which region of Germany you live in, very different degrees of hardness are typical: While the water in some places contains a lot of lime, it is rather soft in other areas, so it is hardly calcareous. Of course, the decalcifying must be done more often if the water contains much lime, because then form faster lime deposits. In areas with soft water, descaling should not be completely abandoned, but it is usually less necessary. Regardless of the hardness of the water, we recommend that you descale the washing machine at least twice a year.

How to Determine the Water Hardness

If you want to find out how calcareous your own water is, you can contact your local water company or the Environmental Agency put in touch. The Internet also provides information about the degree of water hardness in certain regions. If the water is classified at level 4 or even lower, it is low in lime. In this case, it is sufficient to descale the washing machine once every six months. In some areas, however, the water hardness is above the level 7. The water is very calcareous there, so it is worthwhile to use a decalcifying bar every time you wash so that you can not even deposit so much lime. Nevertheless, a thorough decalcification is required at least once a year.

Descale the washing machine - this is how it works

In principle all acids are suitable for dissolving lime. However, you should make sure when choosing that the acid is not too aggressive. Otherwise, the hoses and metals will be in the washing machine.

What utensils are needed?

Depending on whether you want to remove the limescale with household detergents or with a conventional descaler, you will need different utensils.

  • Citric Acid
  • Essig
  • Essigessenz
  • Descalers-Tabs
  • Prowin Descalers
  • Amidosulfonic Acid
  • Dishwasher descaler
  • Dan Klorix

Of course you do not need all the listed products, you can decide which descaler you need

Home remedies or commercially available decalcifiers - What's better?

It's a matter of taste whether you descale with home remedies such as citric acid or vinegar essence. While the typical home remedies available in every household and therefore are inexpensive, the commercial products usually cost more money. But these articles have the advantage that they have been specially developed for descaling the washing machine and therefore certainly attack neither rubber nor silicone of the machine. Although they also contain acids, they are always dosed so that they gently remove the lime.

So-called water softeners are not suitable for descaling. These are tabs that are added to each wash. They serve to prevent limescale by lowering the lime content of the water. However, you can not remove existing calcifications.

When buying, be sure to buy real descaler products.

Descale washing machine with home remedies

If you decide to decalcify your washing machine on the fly, you can use proven Use home remedies to remove limescale deposits.

What home remedies are suitable for descaling?

The most common home remedies used to decalcify the washing machine are vinegar essence or citric acid. However, you should always use such acids with caution. The wrong acidity or too high a dosage can also attack and destroy the small parts of the machine.

We advise against decalcifying with vinegar or vinegar essence. If at all, you should only use this home remedy diluted with water to protect rubber seals and silicone components.

Always dilute the acids with plenty of water to avoid damage. In general: It is better to descale with a strong dilution than rarely with a high-dose acid.

In addition to citric acid and vinegar essence, it is often recommended to decalcify with soda on the Internet. However, we do not recommend that, because even if soaking dirty laundry in soda solution is a very effective home remedy for stubborn stains, soda is not suitable for decalcifying the washing machine.

Decalcifying with citric acid

When decalcifying with Citric acid is best prepared as follows:

Place about eight tablespoons of citric acid directly into the machine's drum.

  1. If you want to use lemon granules, they must first be dissolved in lukewarm water.
  2. Stop Run the program with the highest temperature and let the machine run.
  3. Stop the washing process as soon as the washing machine reaches its highest temperature.
  4. Wait two hours before restarting the washing process.
  5. During When decalcifying, there must be no laundry in the drum nor should you use detergent.

Descale the washing machine with commercially available products.

We If you look around in a drugstore like DM or Rossmann you will find many different descaler. The most commonly used are the special descaling tabs or liquid products such as the Prowin Descaler.

Some testers are convinced that machine descaling works well with Dan Klorix sanitizer. At the same time, it reliably kills germs and germs caused by frequent washing in the low temperature range.

It's best to try out the benefits of using the Dan Klorix Hygiene Cleaner to decalcify the machine. Alternatively you can buy amidosulfonic acid or dishwasher decalcifier. All the products you find in the trade are equally suitable for decalcifying your washing machine.

Liquid descaler or tabs - what is better?

Liquid decalcifier products are usually easier to dose. In contrast, the tabs are often easier to use because they do not have to be resolved first. However, descaler tabs can leave residues because they are optimized for the standard machine sizes. For smaller washing machines, we therefore recommend liquid descaler.

How to descale

Before descalering with commercially available products, you should thoroughly clean the detergent drawer and remove all detergent residues. Also the lint filter usually needs a cleaning. Then insert both again and descale the washing machine as indicated by the instructions for use enclosed with the selected product.

Use a cooking program without prewashing and start the washing process. If your washing machine has a program with a prolonged main wash, you should select this feature. In general, when decalcifying with a commercially available product, it is recommended to stop the wash cycle when the maximum temperature is reached.

How to prevent limescale deposits?

To prevent the formation of annoying limescale, you can consider a few tips. It is important that you do not overdose the detergent, but strictly according to the dosages that the detergent manufacturer indicates. In regions with very hard water, it is best to add a water softener with each wash. This will prevent stubborn calcium deposits from forming again after a short time. However, regular descaling is still on the agenda.
