The main idea is to follow a sequence that ensures soils are removed first, then the surface is properly sanitized and finally allowed to dry so it won’t be recontaminated. Start with washing to physically remove dirt and food residues from the surface. If you skip this step or don’t wash thoroughly, soil can shield microorganisms and reduce sanitizer effectiveness. Next, rinse to remove the soap, loosened debris, and any remaining soil so the surface is clean before sanitizing. Applying sanitizer on a dirty surface wastes the sanitizing step and can leave microbes protected by soils. Then sanitize so that microorganisms are killed or greatly reduced; sanitizer needs to contact a clean, wet surface for the required contact time. If you rinse again or dry before sanitizing, you undermine this step. Finally, air-dry the surface; leaving it to dry prevents recontamination and completes the process because many sanitizers require the surface to remain wet for their stated contact time, and moisture after sanitizing is part of the effective cleaning routine.
