The sporicidal effect of excess liquid from sporicidal wipes was evaluated in comparison to sodium hypochlorite against the spores of three strains of Clostridioides difficile under dirty (3.0 g/L albumin plus 3.0mL/L sheep erythrocytes) conditions. The wipes were soaked in 20 mL distilled water for 4 min. The excess liquid from the soaked wipes was subsequently used in the experiment. Sodium hypochlorite of 0.1% (1,000 ppm) did not exhibit adequate sporicidal activity even after 10 min of contact, whereas sporicidal wipes killed the spores within 5 min. Our results suggest that using sporicidal wipes is effective for disinfecting environments contaminated with C. difficile spores.
