What to expect from your grease exhaust cleaners. A picture guide.
This is what you should expect and demand from your cleaning company, do not acceptexcuses for anything less. Also check behind the fan blades and filters thoroughly and inspect or demand clear pictures from both directions at every access plate. If you do not have adequate access to visuallyinspect the entire duct, hire a competent contractor to install them for you. What you do not see could burn down your restaurant!!!
