Nilfisk-Advance has released ‘a third set of independent test results related to Tennant’s ec-H2O cleaning performance (electrically-activated water used in today’s professional floor scrubbers).’
According to a mid-March press release, the latest set of independent tests measured the cleaning performance of ec-H2O relative to plain tap water using Hucker’s soil, said to be an industry-recognised soil containing no petroleum products and used to test the performance of surface cleaners.
‘The Hucker’s soil testing showed no performance difference between a Tennant scrubber using ec-H2O and the same scrubber using only plain tap water,’ stated Nilfisk-Advance.
“These current test results complete the scientific picture showing that ec-H2O performs no better and no different than plain tap water when used in a commercial floor scrubber,” said Michael Fenger, general manager, product marketing, EMEA/APAC for Nilfisk-Advance. “Nothing in the comprehensive data, collected under controlled and repeatable testing conditions, supports Tennant’s continued claims that ec-H2O acts like a ‘powerful cleansing agent/detergent’.”
Nilfisk-Advance previously commissioned two separate independent tests to measure Tennant’s claims regarding ec-H2O’s performance.
‘The first test used ASTM D4488 soil and showed that ec-H2O water performed no better than when the same scrubber cleaned with plain tap water. Those results also indicated that when cleaning with ec-H2O, the scrubber did not clean as effectively as when the scrubber cleaned with tap water and detergent. The second independent test measured the performance of ec-H2O relative to plain tap water to reduce ATP (adenosine triphosphate). That testing showed that a floor scrubber using ec-H2O reduced ATP to the same level as plain tap water,’ noted Nilfisk-Advance.
“In light of the cumulative, independent industry testing by Nilfisk-Advance and others, we expect that Tennant will cease its unfounded claims that ec-H20 acts like a ‘powerful cleansing agent/detergent’ when used in a commercial floor scrubber,” stated Anders Terkildsen, executive vice president, EMEA sales for Nilfisk-Advance. “These independent test results show that, while ec-H2O may clean floors, it cleans no differently than if the same scrubber used plain tap water. Given the compelling scientific data and the importance of scientifically-proven products, it is rather surprising that Tennant claims to have ‘set the record straight’ and yet has not stopped misstating the performance of ec-H2O.”
