Certified Hardwood Floor Cleaning Technician (NWFA) The NWFA exam goes far beyond basic vacuuming. You’ll navigate wood species identification, pH-sensitive cleaning chemistry, moisture meter readings, and finishing techniques that separate surface damage from legitimate wear patterns. Trap moisture behavior incorrectly, and you risk structural damage claims that dwarf your profit margins.
