What factor determines our choice when buying detergent? Personal experience, advice from friends, advertising? If the tool is proven, has long been positively proven, then there are no questions. Considering how to choose washing powder, experts advise first of all to consider the safety and quality of the product.
The main selection criteria for washing powder
Washing powder is 100% chemical, so it is originally non-ecological. But modern man is so adapted to the overwhelming influence of chemicals in everyday life, that we are only puzzled by the question of which of them is the least dangerous for health. Powders for washing machines must pass the certification procedure, as evidenced by a special icon on the package. But the presence of the badge does not guarantee the impossibility of forgery. You need to be careful when choosing detergents in the stores of economy class, where prices are below the average market. Laundry detergent for automatic machines is often produced in plastic containers of various sizes. Counterfeit products are easy to pack into such containers;It is difficult to identify a fake, so it’s worth comparing the price and appearance of the powder in different stores and not acting according to the “miser pays twice” rule.
The automatic machine safe for health is not necessarily the best for quality. These two criteria are not related. The choice of powder for the washing machine empirically produces the buyer himself, using in turn several equally safe means. The primary choice is affected by advertising, aggressively invading the consciousness of people. In practice, a little-known powder often launders laundry better than the “hero” of the advertising story. Buyers choose the product not only according to the main criteria - safety and quality, but also according to subjective ones: cost effectiveness, pleasant fragrance, etc.

The quality of the powder for automatic washing machines is determined by careful selection and combination of its constituent substances. It is important for the consumer that the information on the packaging of the detergent matches the reality. To verify this, manufacturers( less often consumers) order verification at independent laboratories.
If two powders are checked, a control wash is performed simultaneously on two identical machines. Measure the same amount of detergent, in the drum of automatic machines lay two identical in composition, size, shape and degree of contamination of a piece of cloth. Moreover, contaminated samples are produced in a special way at European enterprises, since their Russian counterparts are not recognized at the world level. For the purity of the experiment, contaminated samples are even placed in the drum machine in the same way. Starting, ending and all washing processes, the amount and temperature of water, energy spent - all these indicators are carefully recorded with special devices. At the end of the wash, the samples are removed from automatic machines and tested on optical equipment: the technique determines invisible differences in the color spectrum of the fabric.

Powder: recommendations for choosing
Detergents are selected according to the types of washing machines, types of fabrics and peculiarities of contaminants on them. Information about the appointment of the powder contained on the package.
Powders with low foaming are used for automatic washing machines. On the packaging of the detergent is the word "machine", depicted a round door or a drawing of a washing machine with front loading. Sometimes the matic prefix is indicated next to the name. In no case can not use powders for hand washing - they will damage the machine-gun.
Instructions for use of detergent tells in detail how much powder is designed for one wash. If too much product is poured into the dispenser, copious foam is formed, which is dangerous for automatic washing machines. When washing 2-3 things, use a smaller amount of powder.
The use of liquid laundry detergent is limited to low temperatures.
If the washing program is running in cold water, the powder is used less than usual: at a low temperature, it is poorly soluble, which means that some amount of the product will be wasted.
Experts advise thin air conditioner for laundry to be diluted with water, so that it can be used without any residue when it is washed, without settling on the walls of the dispenser. Some powders are placed directly in the washing machine drum, and not in a special container. By following these recommendations, consumers will be able to successfully select and economically use detergents, as well as extend the life of their household appliances.
