By using the washing balls, you can use less detergent, avoid using fabric softeners, and save 30% on power consumption. By reproducing the washerwoman's technique, the laundry is beaten, as when it was by hand. The advantage of washing balls is that the fibers in your clothes are spared and that they last longer. In addition, for down jackets or other bulging clothing, the balls prevent the feathers from sticking together and from becoming flattened. The balls are to be put with the laundry in the drum of your washing machine. They work for all garments except lace and tights. Once the washing machine is running, the balls will beat, move and knead the wet laundry without damaging it. The balls are strong and durable. You can put on average 30% less detergent and above all you can spin less quickly. The cycles can also be shorter! Your laundry is then washed in a more ecological way. Washing can be done at low temperature and will allow you to save water and electricity. In addition, the wash balls can prevent the formation of limescale in your pipes and damage the engine. A ball contains an electromagnet which produces magnetic fields when it is in motion to destroy the structure of the limestone and prevent its formation! The must for green maintenance and washing.
