Assessment of Accelerated Hydrogen Peroxide for Sanitizing Carpet

Daniel Price and Brandi Morris. Microbiology, Interface Research Corporation, 1603 Executive Drive, Lagrange, GA 30240

Carpet is a three dimensional porous flooring surface that accumulates both settled and tracked in soil and biocontaminants.  Biocontaminants that accumulate on and in the pile of carpet typically consist of soil-borne bacteria or mold spores.  When carpet becomes damp following a moisture event such as a spill, these accumulated spores may germinate and grow producing offensive odors and stains.  A stabilized and accelerated hydrogen peroxide technology was assessed for the ability to sanitize soiled carpeting.   Sections of soiled carpet were sprayed with the peroxide based cleaner-sanitizer followed by brush agitation.   Following fifteen minutes of dwell time the carpet was vacuum extracted using hot water only.  Enrichment cultures prior to cleaning-santizing and following cleaning-santizing demonstrated effective kill and physical removal of the viable biocontaminants.   The value of sanitizing cleaning of carpet has received little focus.   Most carpet cleaning product claims today center around appearance and allergen removal.   Identification of chemistries that effectively sanitize carpet could help this known indoor biocontaminant sink be more hygienic.
