Exhaust system cleaning is not only recommended but is required by law for all commercial cooking establishments.
The principle function of a Commercial Cooking Ventilation System is to exhaust smoke, fumes and grease-laden vapors out of the building. These exhaust gases leave a grease residue on the inside of the system, which if not properly cleaned can cause dangerous conditions. A basic commercial kitchen exhaust system is composed of an exhaust hood, filters, ducts, fan and a fire suppression system. Other components may include a precipitator and make-up air systems.
The removal of accumulated grease residue is a continually evolving practice, which can be achieve by properly implementing various cleaning methods, regardless of which method is utilized the final result has to be the complete elimination to bare metal of all grease residue accumulated on the system, as mandated by City and State laws and NFPA guidelines.
The most common methods utilized in the cleaning of commercial exhaust systems include; scrape and/or wipe clean, steam clean and power washing. After many years of hands-on field experience, we have developed our unique American hydro cleaning method.
Scrape and Wipe Method “utilizes manual cleaning using hand tools such as scrapers, wire brushes, steel wool and rags. This method is visually effective but inefficient in cleaning hard to reach areas. Companies that only utilize this method have a minimum investment in equipment and personnel training. This approach is often referred in the industry as the rag and tag method.”
Steam Clean Method “utilizes a low-pressure hi-temperature power washing machine. This method is effective but very time consuming and costly. This is the least utilized method in the industry.”
Power Wash Method “utilizes a hi-pressure, hi-temperature power washing machine. The means to control and properly dispose of wash/waste water by funneling into a container thru plastic tarps attached to the exterior of the exhaust hood. This method is affective and recommended by industry certification entities. Companies utilizing this method have a considerable investment in equipment and personnel training.”
