How To Clean Vintage Metal Kitchen Cabinet
Kitchen exhaust cleaning (frequently referred to as hood cleaning) is the process of removing grease that has accumulated inside the ducts, hoods, fans and vents of exhaust systems of commercial kitchens. Left uncleaned, kitchen frazzle systems somewhen accumulate enough grease to become extreme fire hazards.[ane] [2] Exhaust systems must exist inspected regularly, at intervals consistent with usage, to determine whether cleaning is needed earlier a unsafe amount of grease has accumulated.
Cleaning processes [edit]
The exhaust organisation is beginning scraped make clean; sometimes scraping isn't necessary if the grease exhaust arrangement has been maintained properly chemical and hot water, and then done clean with food-safe caustic chemicals and hot water pressure-washing where possible to safely collect the dissolved grease and h2o. The actual commercial kitchen exhaust organisation cleaning guidelines are outlined in the National Fire Protection Association (NFPA). The cleaning frequency depends on the type of food existence cooked and volume of grease laden vapors drawn upwards through hood plenum. For example, one church may require less servicing because they apply the arrangement 10 times a year, while another church would crave more frequent attention because they have a weekly Friday dark fish fry. Typical cleaning intervals are monthly, every two months, quarterly, semiannually and annual.
Caustic chemicals [edit]
Caustic chemicals tin can be applied to suspension downward the grease. After that, hot water can be used to rinse away the residue. Chemicals are generally applied with either a garden-type sprayer, downstream injection through a force per unit area washer or with a chemical foamer.[3]
Once the chemicals are applied, they are allowed to dwell on the surface of the grease for a menses of fourth dimension, before being washed off of the surface with hot water. In extreme situations, where grease buildup is also heavy for a chemical application and a rinse, scrapers may be used to remove excess buildup from the contaminated surfaces, before chemicals are applied.[iv]
Hot water pressure-washing [edit]
Machines can be used that both boil water and and so apply this water under pressures upward to 2,000 pounds per square inch (14,000 kPa). In a common method of preparation, heavy-duty tarps are first clipped to the hoods and then angled into plastic garbage cans to take hold of the run-off. As the cans are filled the contents are tending of successively. The grease should be removed rather than just emptied into the local drains to avoid clogging. Some problems that tin arise from improper horizontal duct cleaning include excessive grease buildup up in inaccessible ductwork. Steam cleaners tend to move the grease further in to the grease duct work, which tin can crusade massive grease accumulations in areas of the duct work betwixt the hood and fan on the roof. Companies using hot water methods should be using a caustic chemical degreaser to break downwardly grease, so that the build upward in inaccessible areas becomes removed by flushing the system with both hot water and caustic degreaser agents.
Finishing [edit]
Cleaners oft shine hoods for easier cleaning and improved appearance. Cleaners apply a certification sticker to the hood of each cleaned kitchen exhaust system to enable the authority having jurisdiction as well equally insurance adjusters and health inspectors to check for compliance with the local, county and state fire codes. Vinegar and warm water can be used to remove any white residue left from the commercial kitchen grease cleaning process.
Regulation [edit]
Many jurisdictions have adopted this nations minimum available standard, National Burn Protection Association Standard 96, Standard for Ventilation Command and Fire Protection of Commercial Cooking Operations,[5] [half dozen] and crave compliance to it past Kitchen Frazzle Hood Cleaners and operators of commercial kitchens.
Industry instruction [edit]

Several associations accept been formed to educate kitchen exhaust cleaners on the provisions of NFPA 96 standard and on the all-time standards and practices for kitchen frazzle cleaning. Among these are:
- International Kitchen Exhaust Cleaners Clan
- Power Washers of North America
- Certified Hood and Duct Cleaners Association
