Cleaning a restaurant hood is two different jobs. Your team handles the parts built to be removed and wiped, on a daily or weekly routine. The parts behind walls, in ceilings and on the roof need equipment, power isolation and a professional crew. This guide covers what your staff can do safely, which products to use on which surfaces, the Dubai rules on cleaning chemicals, and where the professional job begins.
What is the best way to clean a kitchen hood?
Split the work in two. Staff clean the filters, grease cups and canopy surfaces daily to weekly, and a professional cleans the duct, fan and any ESP unit on a schedule set by how much you cook.
The split follows how hoods are built. Dubai Municipality's Food Code requires hood filters to be easily removable for cleaning (section 2.11), so those parts are designed for your team to take out and wash. The ductwork and fan are not designed for that, and grease that gets past the filters collects there.
Most restaurant guides use the same rhythm. FoodDocs splits hood care into daily exterior wiping, weekly filter soaking, and a professional full-system clean. For the professional part, the widely used benchmark is the NFPA 96 inspection schedule, which ranges from monthly for solid-fuel cooking to annually for low-volume kitchens.
Which parts of a kitchen hood can restaurant staff clean themselves?
The baffle or mesh filters, grease cups and troughs, the canopy inside and out, and the light covers. These parts can be reached from the kitchen floor and removed without tools.
The Dubai Food Code expects filters and other grease-extracting parts to come out for cleaning unless they are built to be cleaned in place. Filters and grease cups need the most frequent attention because they catch grease first. The canopy's inside surfaces come next, especially above fryers and grills.
Keep the routine within reach. If a part needs a ladder over hot equipment, a screwdriver or the power switched off at the panel, it belongs to the professional visit.
Which parts of a kitchen exhaust system need a professional?
The ductwork, the exhaust fan, any ESP or ecology unit, and the roof outlet. They sit out of reach, need power isolation and special tools, and hold the grease that filters miss.
Grease in a duct is a fire load. The U.S. Fire Administration found that cooking materials such as grease and oil were the items most often first ignited in restaurant fires. Its report also describes a restaurant fire that spread through a hood and chimney three months overdue for cleaning.
A professional kitchen exhaust cleaning crew reaches the duct through access panels (exhaust duct cleaning), cleans the fan with the power isolated, and services ESP collector cells (ESP unit cleaning). That is why the NFPA 96 frequency table sets a schedule for the whole system and not only the hood.
How do you deep clean a kitchen hood step by step?
Switch off the hood and let it cool, put on gloves and goggles, soak the filters, then degrease the canopy from top to bottom. Empty the grease cups, rinse, dry and refit, always after service and never with burners on.
- Stop cooking and let everything cool. Parts Town's commercial hood guide says to unplug the unit, let it cool and clean during off-hours.
- Put on protective gear. OSHA's restaurant clean-up guidance calls for gloves, goggles and splash aprons when staff handle cleaning chemicals, and for reading the product's Safety Data Sheet first.
- Cover the equipment below with plastic sheeting so drips don't land on cooking surfaces.
- Remove the filters and grease cups and put them in a soak sink (see the next section for which solution).
- Degrease the canopy, inside first, top to bottom. Apply the degreaser at the label dilution, leave it for the time on the label, then scrub with a non-abrasive pad.
- Empty the grease cups and troughs into a sealed container for your used-oil collector, not down the drain.
- Rinse with clean water and dry every surface, so no chemical residue is left near food areas.
- Refit the dry filters with the baffles facing the right way, and check the lights and fan before service.
How do you clean kitchen hood filters (baffle vs mesh)?
Stainless steel baffle filters can soak in a hot alkaline degreaser. Aluminium mesh filters need a mild detergent, because strong caustic cleaners attack aluminium.
Check what your filters are made of before you choose a product. Strong caustic degreasers are based on sodium hydroxide, and sodium hydroxide reacts with aluminium, dissolving the metal and releasing hydrogen gas. Repeated soaks weaken mesh filters and leave them dull and pitted. Stainless steel baffles tolerate alkaline degreasers well.
For the soak itself, HoodMart recommends very hot water, a 10 to 15 minute soak and a non-abrasive brush. Heavier build-up needs longer: Parts Town suggests 2 to 3 hours or overnight in warm water with degreaser. HoodMart's suggested interval of every 6 to 8 weeks is too long for a busy fryer or grill line, where weekly is more realistic.
The Dubai Food Code requires filters that can be removed for cleaning or replacement. If a filter is bent, torn or no longer seats tightly, replace it, because grease will bypass it into the duct.
How do you remove sticky grease from a stainless steel hood without streaks?
Degrease first, then rinse with clean water and dry along the grain with a microfibre cloth. Streaks are usually leftover cleaner or hard water, not grease.
Sticky grease needs an alkaline degreaser and some dwell time before you wipe. Wiping too soon smears it into a thin film. Once the grease is off, rinse with clean water to lift any cleaner residue.
Dry immediately, wiping in the direction of the steel's brushed grain. Dubai's tap water leaves mineral spots if it air-dries on steel, so a dry microfibre cloth makes the biggest difference to the finish.
What chemical should I use to clean my kitchen hood?
Use an alkaline kitchen degreaser registered for sale in Dubai, at the dilution on its label. Match its strength to the surface: caustic products on stainless steel only, mild detergent on aluminium and painted parts.
Grease is fat, and alkaline cleaners break fat down, which is why nearly every commercial kitchen degreaser is alkaline. The question is how strong. OSHA warns that oven and grill cleaners can be caustic and cause skin burns and eye irritation, so the strongest product is not automatically the right one.
In Dubai the product also has to be legal. Dubai Municipality's Technical Guidelines for Detergents say no detergent may be sold or distributed in Dubai unless it is registered in the Montaji system. Labels must carry GHS hazard warnings in English and/or Arabic, which is also where your staff find the dilution and protective gear for each product.
| Cleaner | What it does to grease | Safe on | Avoid on | Best used for |
|---|---|---|---|---|
| Hot water and dish detergent | Lifts light, fresh grease | All surfaces | Nothing | Daily wipe of the canopy and light covers |
| Baking soda paste | Mild scrub for sticky spots | Stainless steel, aluminium | Brushed steel if rubbed hard | Spot cleaning between deep cleans (HoodMart's method) |
| White vinegar | Little effect on grease | Stainless steel | Natural stone nearby | Water spots and mineral marks |
| Alkaline kitchen degreaser | Breaks down set grease | Stainless steel; most products also aluminium at weaker dilution (check the label) | Painted or coated parts at strong dilution | Weekly filter soaks and canopy deep cleans |
| Caustic oven or grill cleaner (sodium hydroxide) | Strongest common degreaser | Stainless steel baffles | Aluminium mesh (reacts with the metal), skin and eyes (OSHA) | Heavy build-up on steel, with gloves and goggles |
| Solvent or citrus degreaser | Dissolves sticky residue | Most metals | Hot surfaces and open flames | Small spots of tacky residue |
Only use products registered in Dubai Municipality's Montaji system, and follow each label's dilution and protective gear.
What is the best degreaser for a kitchen exhaust fan or extractor hood?
For the hood canopy and steel baffle filters, a commercial alkaline degreaser. The exhaust fan itself is a professional job, because it has to be isolated from power and opened up.
On the canopy, a food-service alkaline degreaser at the label dilution handles most build-up. Use the protective gear OSHA lists for caustic cleaners: gloves, goggles and a splash apron.
The fan usually sits on the roof or in a ceiling void, with blades and a motor that must be locked off before anyone touches them. It is part of the full-system clean in the NFPA 96 schedule, not the staff routine.
Can I use oven cleaner on kitchen hood filters?
On stainless steel baffle filters, yes, with gloves and goggles. On aluminium mesh filters, no: sodium hydroxide reacts with aluminium and weakens the filter.
Most heavy-duty oven cleaners are caustic. On steel baffles they cut through baked-on grease quickly. On aluminium, sodium hydroxide dissolves the metal and gives off hydrogen gas, so mesh filters corrode and stop sealing properly.
Whichever filter you have, spray in a ventilated area, never near a hot surface, and follow OSHA's advice to read the Safety Data Sheet before use.
What is the most powerful degreaser, and is stronger always better?
Caustic (sodium hydroxide) cleaners are the strongest degreasers commonly available. They are also the most likely to burn skin and damage aluminium, so use the mildest product that does the job.
Strength comes with risk. OSHA lists caustic oven and grill cleaners among the chemicals that cause skin burns in restaurant clean-up, and caustic solutions attack aluminium.
A weekly routine with a standard alkaline degreaser stops grease from building up to the point where caustics are needed. If staff need the strongest product every week, the hood or duct is probably overdue for a professional clean.
What dissolves thick grease?
Heat, an alkaline cleaner and enough time on the surface. Thick or carbonised grease, the kind that builds up in ducts, usually needs mechanical scraping or brushing as well as chemicals.
On the canopy and filters, warm the solution, let it sit for the full time on the label, then agitate. Most failed cleans come from wiping too soon, not from a weak product.
Old grease in a duct is different. Heat from the cooking line bakes it into a hard layer that chemicals soften only on the surface. That layer is also what makes duct fires dangerous: the U.S. Fire Administration found that grease and cooking oil were the materials most often first ignited in restaurant fires. Removing it takes access panels, scrapers and rotary brushes, which is professional work. If that's your situation, see our kitchen hood cleaning in Dubai service.
What is a good homemade grease remover?
Hot water with dish detergent handles light daily grease, and a baking soda paste helps with sticky spots. Neither replaces a commercial degreaser for weekly filter soaks in a busy kitchen.
For the daily wipe, hot water and a squeeze of dish detergent is enough on fresh grease. For a mild scrub, HoodMart's filter method mixes about half a cup of baking soda with dish soap into a paste and pairs it with a hot soak.
We found no independent test comparing homemade mixes with commercial degreasers on kitchen grease. So treat homemade options as a light-duty routine, not a replacement for a proper degreaser on a fryer or grill line.
What household cleaner removes grease?
Dish detergent is the most effective household option, because it is made to break up fat. Never mix cleaners, especially bleach with ammonia-based products.
Dish detergent is gentle on every hood surface and safe around food areas once rinsed. Multi-purpose sprays vary widely, so check the label before using one near food.
Mixing products is where household cleaning becomes dangerous. OSHA warns that chlorine bleach and ammonia together create a toxic gas. Use one product at a time and rinse between them.
Does vinegar remove kitchen grease?
Not well. Vinegar is an acid that works on mineral scale and water spots, while grease responds to alkaline cleaners, so save vinegar for the final shine on stainless steel.
Vinegar has a place in the routine: a diluted spray removes the white mineral marks Dubai's water leaves on steel. On grease itself it does little.
Don't mix vinegar with baking soda in the same step either. They neutralise each other, leaving mostly salty water with less cleaning power than either one alone.
Which cleaning products are allowed in Dubai restaurant kitchens?
Any detergent sold or used in Dubai must be registered in Dubai Municipality's Montaji system and carry GHS hazard labels in English and/or Arabic. Separately, Dubai Municipality bans acids, caustics, solvents, enzymes and emulsifiers when grease traps are cleaned.
Under Dubai Municipality's Technical Guidelines for Detergents (version 3.0, 2024), no detergent may be manufactured, imported, sold or distributed in Dubai unless it is registered in Montaji. Registration lasts five years. The guideline covers household, industrial and food-contact cleaning products, so it applies to kitchen degreasers. Before you reorder a product, ask your supplier to confirm its Montaji registration.
The second rule is about drains. Dubai Municipality's grease trap guideline states that "it is strictly forbidden to use acid, caustics, solvents, enzymes or emulsifying agent when cleaning grease traps." Don't pour caustic or enzyme products down the sink to shift grease in the trap. Leave the trap to your licensed grease trap contractor.
How often should a restaurant clean its kitchen hood?
Staff should clean filters and grease cups daily to weekly, depending on how much you fry and grill. The whole system needs a professional clean monthly for solid-fuel cooking, quarterly for high volume, twice a year for moderate volume and yearly for low volume.
The staff routine depends on what you cook. A fryer and grill line fills filters quickly, so weekly soaks are a sensible minimum, and FoodDocs recommends a daily exterior wipe and weekly filter soaks. A cafe that mostly bakes and reheats can stretch the soaks further apart. The Dubai Food Code requires hoods that stop grease collecting on walls and ceilings, which only works if the filters stay clean.
For the full system, the common benchmark is the NFPA 96 inspection schedule:
- Monthly: solid-fuel cooking such as charcoal or wood
- Quarterly: high-volume cooking, including 24-hour operations, charbroiling and wok cooking
- Every six months: moderate-volume cooking
- Yearly: low-volume cooking such as seasonal or occasional kitchens
NFPA 96 is a U.S. standard. We found no public UAE regulation that sets a fixed professional-cleaning interval for the whole exhaust system, so treat this table as the industry benchmark and confirm it with your inspection results. More on how often to clean your hood, and see our guide on how often to clean a commercial kitchen exhaust in the UAE.
What safety precautions should staff take when cleaning a hood?
Switch off and cool the hood, wear gloves, goggles and a splash apron, read the product's Safety Data Sheet, and never mix chemicals. Never climb onto cooking equipment to reach the canopy.
OSHA's restaurant clean-up guidance covers the essentials. Oven, grill and drain cleaners can be caustic and burn skin and eyes. Employers should provide gloves, goggles and splash aprons, and staff have a right to read the Safety Data Sheet for every product. Bleach and ammonia must never be mixed.
Add two kitchen-specific rules. Clean only after service with burners and fryers off and cooled, as Parts Town advises. Use a proper step platform, never a fryer or range top, to reach the canopy.
Frequently asked questions
Can I use bleach to clean a kitchen hood?
Bleach is a disinfectant, not a degreaser, so it does little to grease and is the wrong tool for a hood. Never use it alongside ammonia-based cleaners, because OSHA warns the mix creates a toxic gas.
How long should hood filters soak in degreaser?
For light grease, HoodMart suggests 10 to 15 minutes in very hot water, followed by a non-abrasive brush. For heavy build-up, Parts Town suggests 2 to 3 hours or overnight, using the dilution on your degreaser's label.
Can I put hood filters in a commercial dishwasher?
Many stainless steel baffle filters can go through a commercial dishwasher, but check the filter maker's instructions first. Aluminium mesh filters can discolour or corrode in strongly alkaline dishwasher detergent, so hand-wash them in a mild solution.
Is it safe to clean a kitchen hood during service hours?
No. Clean after service with the burners and fryers off and cooled, as Parts Town advises for commercial hoods, so staff aren't working above hot equipment and chemicals stay away from food being prepared.
