C. difficile spore removal from surfaces using spray only versus spray and wipe cleaning processes. The data presented in A) represents "spray" only with no wiping of the surface prior to sampling with Rodac plates, whereas the data presented in B) represents a combination of "spraying" followed by "wiping" (single pass of the cloth) after 3 minutes of contact time. Those bars indicated by "*" represent all three samples where the number of colonies on the Rodac plate was too high to count, therefore, the samples were assumed to have ≥4log₁₀ cfu/site for graphing purposes.
