NEW YORK — The National Advertising Division (NAD) of the Council of Better Business Bureaus has recommended that Tennant Company discontinue certain claims promoting the superior performance of the company''s "ec-H20" technology, according to a press release.

The claims at issue were challenged before NAD, the advertising industry''s self-regulatory forum, by Nilfisk-Advance Inc., a competing manufacturer of commercial floor cleaning equipment, the release stated.

According to the release, claims at issue included:

• ec-H20 "electrically converts water into a superior cleaning solution."
• "Independent studies show that ec-H20 outperforms [many] conventional chemicals."
• "ec-H20 technology makes water perform like a powerful detergent."
• "Tennant ec-H20 is proven to reduce environmental impact by up to 98 percent."

In reviewing the advertiser''s testing, NAD acknowledged that the scientific analysis and collective testing evidence provided a foundation for the utility of the ec-H20 technology in commercial scrubbers and for its general efficacy as a cleaner, the release noted.

NAD determined, however, that the advertising communicated a message of superior cleaning performance, which was not supported by the evidence of comparative testing in the record, the release added.

Shortly after the NAD recommendation came down, Nilfisk-Advance issued a press release of their own regarding the ruling, which can be read in its entirety here.
