Washing powder washes visually residue and the washing result is very compelling. After the wash cycle, the laundry is clean, but it's no longer a smell in the fibers of any fragrances. The laundry smells not neutral or basic. Thus, in our view, a really compelling product. Since we know of no comparable and cheaper product, we subtract no star for the fairly high price. However, a price reduction (perhaps by selling in a larger packaging unit) us seems helpful and would therefore our suggestion for improvement. The powder itself deserves 5 stars. So a washing powder should be designed, in our view.
