Welcome to the Professional Shower & Bathtub Cleaning Certification Course. Showers and bathtubs are high-moisture environments that accumulate soap scum, hard water buildup, mold, mildew, and body oils. Proper cleaning requires structured workflow, correct chemical usage, surface awareness, and attention to detail. This course teaches you how to professionally clean, disinfect, and restore showers and bathtubs to certification-level standards while protecting surfaces from damage.
