"A laundry ball or washing ball is a product promoted as a substitute for laundry detergent. Producers of laundry balls often make pseudoscientific claims about how these balls work and exaggerate the extent of their benefits.[1][2]
In the United States, laundry balls have been sold on home shopping channels or by participants in multilevel marketing,[1][3] although this is not the case in all countries.
Washing with laundry balls is as effective or less effective than washing without detergent.[4][5] The effect can largely be attributed to the mechanical effect of the ball or to using hot water instead of cold water.[4][6]
The Federal Trade Commission has taken action against manufacturers for making misleading claims,[7] while consumer organizations have recommended against buying this type of product."
