Claimed Mechanisms of Action
Manufacturers rarely agree on why their laundry balls work, hinting that these claims are just made up by each individual manufacturer. Some claims are not backed by science, while others are an exaggeration of benefits. Balls that contain detergents may offer more cleaning power than water alone because their ingredients are comparable to normal washing powder, but in smaller quantities. It is claimed that conventional washing powder manufacturers recommend using more powder than is necessary, and that these powders contain unnecessary fillers or fragrances.
The effect of the laundry balls may be explained by simple mechanical action and by the usage of hotter water. Some manufacturers claim that their products reduce energy consumption, but their pamphlets recommend using hot water. Hot water will clean some types of spots better than cold water, leading some people to conclude that the balls worked. The mechanical action of the laundry balls can help clean some types of spots, but a golf ball will achieve the same effect for much less money.

Famous quotes containing the words claimed and/or action:
“In contrast with envy, which usually occurs between two people and is focused upon another person’s qualities or possessions, jealousy occurs when a third person becomes a threat to a dyad. Jealousy involves the loss or the impending loss of a relationship that one wants to hold onto, a relationship that is vital to personal fulfillment and claimed as one’s own.”
—Carol S. Becker (b. 1942)
“Without our being especially conscious of the transition, the word “parent” has gradually come to be used as much as a verb as a noun. Whereas we formerly thought mainly about “being a parent,” we now find ourselves talking about learning how “to parent.” . . . It suggests that we may now be concentrating on action rather than status, on what we do rather than what or who we are.”
—Bettye M. Caldwell (20th century)
