I have been reading about this for a while this morning because this was interesting to me. I started off with the site you mentioned. It sounded good. Then I typed in magnetic laundry con
into my search engine. To make a long story short, my findings are that it seems that these magnets do not do anything more than cleaning with plain water would have done. Here is a quote from this site http://www.consumersearch.com/laundry-detergent/review"There are many varieties of laundry balls that purport to replace laundry detergent by modifying the structure of water to make it clean better. The Life Miracle Laundry System (*est. $50) uses a "powerful, specially calibrated magnetism to help alter the basic nature of water and increase its natural solvency," (according to the manufacturer). The website lists dozens of testimonials from happy customers. However, in a test by Australia's Choice magazine, this product achieves similar results to washing with plain water. An informative website called "H2O dot con" is helmed by a former chemistry professor; Stephen Lower discusses the inaccuracies behind the scientific claims made by the manufacturers of these magnetic laundry products. The writer concludes that, "The best that can be said of magnetic laundry balls is that they help agitate the fabrics, but you can accomplish the same thing by dropping a rock into the washing machine. Otherwise, these devices are worthless."
Then I also found this site in which a man bought the magnets (from the same company listed above) and did some tests of his own. He posts an article, then the company posts a reply and this final one is his reply to the reply.
Some of it seems a little petty, but at the same time, he makes some interesting points. Might be worth a read. http://blog.kamens.brookline.ma.us/~jik/wordpress/2009/01/04/more-on-the-magnetic-laundry-scam/
Then there was another site that compared the comments made by these magnetic companies to actual facts or scientific data. That table was interesting to read. Just scroll down a little.http://www.chem1.com/CQ/magscams.html#MLA
All of that to say - that some of this research seems to be based on a different company than the one you mentioned, but the concept seems to be the same - magnets covered by a rubber coating that you leave in your washer to wash with the laundry.
I also typed in magnetic laundry pros
and could not find any websites that give any pros to these products that was not also trying to sell them.
I just thought I'd post what I read and found. I'm not really stating an opinion yet. Would like to do some more research - but am out of time now.
