Car Wash Service SOP for Work Training

I am seeking assistance revising and improving the Standard Operating Procedures (SOP) for our Car Wash Service, which is part of our program. This service provides work training opportunities for individuals with intellectual and developmental disabilities. Please revise, expand, and organize the existing SOP to ensure it is clear, professional, and suitable for operational use, staff training, and supervision. The document should read like a professional workplace SOP, not an academic paper. The procedures should include clear sections such as purpose, scope, roles and responsibilities, safety procedures, equipment and supplies, vehicle wash procedures, quality control, incident reporting, and training expectations. The service may operate at fixed locations or as a mobile car wash, and individuals work alongside staff supervisors (Instructors). The SOP should emphasize safety, clear step-by-step procedures, and supervision expectations.
