Keeping things clean is uber-important. We've already covered sanitation, but cleanliness is different. On the Servsafe Sanitation test, one question is always to distinguish between the two. Clean is defined as the absence of visual soil, sanitized focuses on non-visible microbial contaminants. The gist of all of this is to use your soapy water to keep things clean and then the sanitizer to disinfect once the surface is clean. Make sense?
