Things should look fresh after washing, and stains should be washed off. If the stains are in place, and the things have an unpresentable appearance, then most likely the washing powder was selected incorrectly.
What are the types of laundry products?
There are powders for hand washing — they have a gentle composition and strong foaming. The powder does not cause irritation on human skin. You can not use such a powder for washing in a machine. There will be too much foam, and it can disable the equipment.
Machine wash powders are more aggressive to things (and, accordingly, the skin of your hands) and less foaming.
There are also gels, capsules, and machine wash plates. They do not replace each other, but are designed for different types of fabrics, for different washing modes and even for different degrees of contamination.
The powders can be for colored or white linen. Chlorine and other bleaches may be present in the powder for white fabrics.
Why can’t hand-washing powder be used in a washing machine?
“The fundamental difference between hand wash and machine wash powder is their ability to form foam. When hand washing, it is important that the powder foams well. After all, the foam facilitates the process of hand washing itself. In the foam solution, things are better washed, because the foam helps to “pull out” dirt from the tissues. Powder for automatic machines, on the contrary, should not form an abundant foam, since it will worsen the washing mechanism. The fact is that in cars, the drum lifts the laundry to the topmost position, from where it falls down, hitting the water. Too much foam will not allow him to flutter so freely in the drum, which means that the laundry will be worse to wash,” explained process chemist Tatyana Mikhailova.
