Janitorial work varies enormously by environment — a 10,000 sq. ft. retail store and a 200,000 sq. ft. hospital have very different cleaning standards. Always state the facility type (healthcare, commercial office, educational, industrial) and square footage you were responsible for. This context tells the reader exactly what level of complexity you can handle.

Professional janitorial contracts are governed by inspection schedules and quality benchmarks. If you've consistently scored 90%+ on facility inspections, include those numbers. Passing scheduled audits is a measurable proof of professionalism that most janitorial resumes neglect — yours will stand out by including it.

Knowledge of GHS labeling, SDS sheets, correct chemical dilution, and OSHA hazard communication is legally required for professional cleaning roles. List every piece of power equipment you've operated (ride-on scrubbers, high-speed burnishers, carpet extractors) to demonstrate that you go beyond mops and brooms. This technical depth signals a career professional, not a temporary hire.
