Characteristics of swabs and swab surfaces were analyzed. For recovery from bacterial biofilms, the swab efficiency was 40% lower than those of wet surfaces. Our team has years of experience working with commercial property owners to keep their building safe and healthy for anyone working or visiting the area.
