Kitchen Exhaust Grease: Why It Returns After Cleaning Fast<\/p>\n\n\n\n

Have you ever spent an entire afternoon scrubbing your kitchen counters and\u2002still had a layer of grime on your stove hood? You clean it with a damp cloth but the\u2002sticky film comes back in a day or two. It’s so frustrating many homeowners in\u2002Australia have been battling this irritating issue during their weekly home-cleaning regime. The issue is rarely your effort rather it comes down to how vapourized cooking fats move through your home’s ventilation system.<\/p>\n\n\n\n

In this blog we will discuss why grease accumulates so quickly around cooking zones, how airborne oils behave and why professional kitchen exhaust cleaning is necessary to keep your home fresh, hygienic and completely safe from potential fire hazards.<\/p>\n\n\n\r\n

<\/div>\n\n\n

The Physics of Airborne Cooking Oils<\/strong><\/h2>\n\n\n\n

On cooking of sausages or searing of steaks, liquid fat turns into little vaporization droplets in the air. The resulting hot vapors rapidly rise up with water vapour and hot air from the cooking surface. When the air becomes cooler it results in oil fumes condensing into viscous liquid particles on any cold neighbouring surfaces. Removing the oil residue just by wiping the surface only gets rid of the fresh layer. Through each time you heat up and use your stove burners this stubborn film is going to be building up more and without regular, intensive cleaning it will just continue to accumulate on your stovetops.<\/p>\n\n\n\n

<\/span>Saturated Mesh and Baffle Filters<\/strong><\/h2>\n\n\n\n

Your range hood uses metal mesh or baffle filters to separate oil droplets from the air before they get into the internal ducting. These thin metal ducts are glazed with solidifying grease layers after weeks of daily cooking. Once the filter mesh is blocked entirely, it is unable to capture anymore the airborne oil which is entering. Keeping filters clean is one of the most effective ways to minimise grease buildup, according to relocation cleaning experts<\/a><\/strong>, and improve kitchen ventilation. Far from filtering and collecting the rising vapor, a clogged filter causes the great air to bounce back on the metal holder. The extra oil deposits on nearby cabinets,\u2002backsplashes and ceiling tiles. Routine range hood maintenance in cleaning the filter screens will help prevent them\u2002from becoming clogged and allow them to continue capturing airborne oil efficiently.\u00a0<\/p>\n\n\n\n

Poor Ventilation Airflow and Suction<\/strong><\/h2>\n\n\n\n

Poor ventilation fan performance or size leads to sticky film on all kitchen surfaces around the fan. If\u2002the power of your fan motor is not strong enough, the hot vapours of oil stay longer in the room they are not immediately taken out. The\u2002air they left behind helped grease coat the tops of high cabinets and adjacent walls. Also the use of incorrect duct sizes and the use\u2002of flexible ducts with sharp bends seriously restricts the overall airflow. When the air is starved for a smooth exit from your home, oily vapour is trapped and recirculated back\u2002into the room. The higher capacity fan with a clean ducting path will improve the efficiency of suction and keep your surrounding area cleaner for longer. <\/p>\n\n\n\n

Hidden Oil Build-Up in Internal Ducts<\/strong><\/h2>\n\n\n\n

If your range’s exterior stainless steel surfaces appear sparkling clean after you simply wipe them, the condition of internal ductwork is usually much different. In reality your cleaning filters take care of most oil vapours, a certain portion of it still reaches your internal vent pipes where you can see it as a layer of viscous flammable residue. The continuous flow of grease is also the reason why a freshly cleansed edge of the hood appears oily and sticky a few hours after being washed. Full kitchen exhaust cleaning concentrates on these hidden internal areas to halt oil from running back down onto your\u2002stovetop. <\/p>\n\n\n\n

Ineffective Household Cleaning Agents<\/strong><\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Employing ordinary all-purpose surface sprays or dish soaps\u2002in the mild end of the spectrum usually makes the sticky grease worse. Household cleaners are intended for\u2002light soil and spills that are water soluble, not heavy, polymerized lipids. When sprayed on thick layers of oil these mild products just spread the grease out, resulting in a large, blurry film\u2002on the surface of the stainless steel. To shatter stubborn oil bonds efficiently,\u2002you have either to use alkaline based degreasers or natural chemical reactions with warm water, baking soda and dishwashing liquid. Breaking down the chemical make-up of animal fats and vegetable oils properly ensures that grease is lifted out rather than being spread onto neighboring\u2002surfaces. <\/p>\n\n\n\n

Fire Hazards of Accumulated Fat Residue<\/strong><\/h2>\n\n\n\n

Built-up oil in vent systems is not just a nuisance to clean, it is a serious\u2002home fire risk. Cooking oils are combustible and when confined in a tight space such as an exhaust duct they can\u2002ignite if a flare-up in this space kitchen bottom happens on the cooktop below. Fire authorities around the country are saying that kitchen grease\u2002fires are travelling quickly through sooty ducts. Routine monitoring and hood cleaning help\u2002to prevent hazardous fuels from accumulating immediately above hot cooking surfaces. Having a clean and grease free canopy, filters and fans will\u2002keep your kitchen safe for your whole family. <\/p>\n\n\n\n
