LR of S. aureus, M. luteus, P. aeruginosa, E. coli and S. hominis after a simulated main wash cycle (60 min at 30 °C) in the Rotawash using liquid detergent. A washing cycle without addition of acetic acid, a wash cycle with addition of 0.3%L acetic acid and a wash cycle using 0.75% acetic acid. The different values for LR max [+] (indicating a complete reduction of the microbial load) were obtained due to different initial loads. (n = 3)
