IMO it not only did nothing, but "ruined" what would have been a very good washing action, especially on westinghouse machines with the swirly agitator.similar activator (forgot the name of it).
In the franklin, Wizard, western auto whatever machines the counterproductive indexing effect was slightly mitigated by the upper round vanes of their agitator styles.
Really a pity.[this post was last edited: 8/22/2014-11:02]
