Cleaning a Home Kitchen Like a Commercial Kitchen
Ontario's commercial food service regulations — enforced through local public health authorities under the Health Protection and Promotion Act — require commercial kitchens to meet sanitizing and cleaning standards that far exceed what most Ontario homeowners apply at home. Some of those commercial practices translate directly and usefully to residential kitchens.
Clean, Rinse, Sanitize
Commercial kitchens use a three-step sequence for all food contact surfaces: clean (remove visible soils with soap and hot water), rinse (remove soap residue), sanitize (apply a sanitizing solution to kill bacteria). Most Ontario home kitchen cleaning stops at step one (clean) or two (rinse). Adding step three — a food-safe sanitizer spray (hydrogen peroxide-based sanitizers are available at Ontario grocery stores) left on for 30 seconds before wiping — on cutting boards, counters, and sink surfaces after food preparation brings commercial-grade hygiene to the home kitchen.
Cross-Contamination Prevention
Commercial kitchens use colour-coded cutting boards for different food types (red for raw meat, green for vegetables, etc.) to prevent cross-contamination. This practice is worth adopting at home — different cutting boards for raw meat vs. ready-to-eat foods, washed with hot soapy water and sanitized between uses.
Temperature
Commercial kitchen cleaners use water as hot as 80°C for sanitizing dishwasher cycles. Home dishwashers in Ontario typically run at 55–65°C — hot enough for sanitizing if the "sanitary" or "heavy" wash cycle is used. For manual dishwashing, as-hot-as-tolerable water (with rubber gloves) and allowing dishes to air dry (rather than towel drying) reduces recontamination.
