Abstract Use of hydrogen peroxide against Escherichia coli on surfaces based on concentration and time using response surface methodology was studied. Models for E. coli reduction were developed for stainless steel, ceramic, plastic, glass, rubber, and wood treated at 1,100 ppm for 5 min. Reduction values of E. coli were 1.68, 1.33, 1.31, 1.28, 1.24, and 1.14 log CFU/cm2. All models were significant (p
