Certified Commercial Cleaning Specialist (ISSA) The ISSA exam assumes you’re fluent in infection control protocols and understand EPA-registered disinfectant chemistry—not just surface-level cleaning. Expect detailed questions on microbial resistance, contact time requirements, and how dilution ratios affect efficacy. If your background lacks hands-on commercial facility experience, dedicate study time to OSHA bloodborne pathogen standards and the distinction between sanitizing and true disinfection. Gaps here compound quickly.
