"The Hood Service does not include scouring, or the use of power tools and does not including the cleaning of inaccessible areas or removal of pre-existing carbon deposits, baked on deposits, or stains, cleaning of back-splash panels, roofs, parking lots, or other building interior or exterior areas"
A cleaning company claiming to clean to NFPA96 standards actually has this in their contract and also on their web site. Make sure to read the entire contract when hiring kitchen exhaust cleaning companies so the something like this is NOT in the contract. A company doing proper and thorough cleaning would never have this in their contract as they can clean everything. Unscrupulous companies could claim anything they leave is either "Baked on", Pre-existing", or "inaccessible". NFPA96 requires ALL combustible material to be removed!! I wonder what they actually do clean? Believe it or not, this is actual words from their work order.:
