Yes, they are, according to researchers at the University of North Carolina Health Care System and University of North Carolina School of Medicine, Chapel Hill, NC.


According to the authors of a study published in the American Journal of Infection Control, microfiber mops removed or inactivated far more microbes than cotton string mops (95% versus 68%) when used with standard detergent. Testing those same mops with a disinfectant did not improve results with microfiber (it still removed or inactivated 95% of germs) but significantly improved results with the cotton mop (microbe removal or inactivation went from 68% to 95%).


Researchers Rutala, Gergen, and Weber conducted tests in 24 rooms, and RODAC plates were used to determine before and after microbe levels.

It was "inactivation" with disinfectant added not "removal". Bill Rutala

Mr. Smith,

Thanks for your query. I have put the question to Dr. Rutala, and await a response.

Curious. Why did adding a disinfectant to the cotton string mop improve its "removal" percentage? Removal is a mechanical action. Does disinfectant make the string mop "stickier", but not so with the microfiber mop?
