The Taguchi method of statistical analysis was used to study the parameters used for estimating the effectiveness of cleaning procedures for removing biofilms from stainless steel surfaces. Bacillus subtilis, Listeria monocytogenes, Pediococcus inopinatus and Pseudomonas fragi were used in the tests. The results showed that the surface roughness of the stainless steel was the most important parameter affecting the cleanability of the surface.
