Schematic diagram of the Formica surface used for wipe testing. Two meters of Formica were delineated into 0.5 m2 sections. Approximately 2.5 × 107 log10 CFU of S. aureus or P. aeruginosa were spotted onto the i-zone (red dots). The surface was wiped in an up and down pattern as indicated by black outlined arrows from left to right. Light grey squares 10 cm × 10 cm (100 cm2) were sampled to recover potentially cross-contaminated S. aureus or P. aeruginosa
