As you know, deep cleaning your restaurant and the commercial kitchen does not just give it a beautiful, sparkling appearance, it also keeps your customers and employees safe! During the COVID-19 pandemic, this level of safety is more important than ever.
The COVID-19 pandemic has ushered in a new reality for the restaurant industry: social distancing, altered operating standards, and the need for intense cleaning. Keeping your kitchen sanitary will help keep your customers both safe and happy, as well as more likely to return to your establishment.
Having a professionally cleaned restaurant implies a high level of care for your customers. So here is all you need to know about maintaining your commercial kitchen during the COVID-19 pandemic, straight from the professionals themselves.
Cleaning During COVID-19
Why is it so important to keep your kitchen clean and sanitized during the COVID-19 pandemic? The viral outbreak caused by COVID-19 was declared a global pandemic on March 11, 2020. With over 4.5 million cases worldwide, and over 350,000 reported deaths due to the virus, it has caused devastation on a global scale.
COVID-19 can cause severe respiratory problems including trouble breathing, fever, loss of smell and taste, and even blood clots. Unfortunately, COVID-19 has had a major impact on the restaurant industry, with restaurants either forced to close or operate at a lower capacity. It has been connected to incidents at many restaurants, eateries, and coffee shops, including Starbucks, Panera, and Waffle House.
Gaining customer trust as restaurant limitations are raised depends on more than just handling food safely. Having your restaurant cleaned and sanitized by a professional company is a prime way to show your customers that you are taking this seriously. This entails cleaning your kitchen appliances, walls, floors, dumpsters, ceilings, vents, grease ducts, hoods, and fans.

The front of the house gives off the first impression that your customers will get of your restaurant. Taking the following steps will ensure that their first impression is a good one and that you are taking the sanitization of your restaurant seriously.
Sanitizing tables, countertops, registers, floors, walls, and bathrooms. This will mitigate the risk of transmitting or contracting COVID-19. The virus can live on surfaces for hours. Wiping down surfaces and continually participating in restaurant cleaning help stop the spread of the virus.
Make sure you are using cleaning solutions that are proven to eliminate COVID-19. Not all cleaning solutions are effective in killing the COVID-19 virus. Make sure you use cleaning solutions that are certified to be effective in eliminating COVID-19.
Back of the House
The back of the house is where you are making the magic happen! Because there is so much going on, the back of the house also gets dirty. Food is being made; dishes are being taken out, and messy plates are being brought back in. Even now, while many restaurants are not fully open, the back of the house remains busy. Below are some steps that your restaurant can take for the back of the house cleanliness.
Sanitizing countertops, prep areas, cooking equipment, refrigerators, walk-in coolers, food storage areas, sink areas, floors, walls, and ceilings. These are the areas and surfaces where food is handled and prepared. It is imperative that they clean and sanitized regularly, especially during the COVID-19 pandemic.
Ensure there is soap, clean towels (or paper towels), and accessible sinks. Your staff is working hard to make sure that your restaurant stays open, safe, and profitable. Make sure that they also have the tools needed to stay safe in the kitchen!

Restaurant Equipment – Denver, CO: Commercial kitchen restaurants should be cleaned and inspected regularly, which includes appliances. For best results, a schedule should be devised so that all stoves, fridges, deep fryers, ovens, and ventilation hoods are assessed for defects and damages. Those appliances should also be put on a regular cleaning schedule. This keeps your commercial kitchen operating as it should, no matter how busy you get. All it takes is for one component to shutting down or malfunction and you could have a big and expensive mess on your hands. Restaurants that have a plan in place for repairs, for example, tend to spend half as much as other restaurant owners who don’t plan ahead. To help you save, we’ve devised a list of ten things to think about when determining how often to maintain and clean your commercial kitchen appliances.
1- Make Cleaning a Priority
If your commercial kitchen isn’t cleaned adequately, your staff could get sick, customers could fall ill, and pests could pose as unwanted guests. While your staff may do most of your cleaning, especially during their night closing duties, it is very easy to forget about cleaning a deep fryer or meat slicer. For this, we recommend hiring a professional commercial kitchen company like APS-Hoods, which can ensure every appliance is adequately cleaned for bacteria and virus removal. And so that you can remain in the health inspector’s good graces.
Monthly cleaning would ensure that your kitchen appliances always remain sanitized for when the health inspector rolls through. Even quarterly deep cleaning services can keep grease from building up and appliances from getting too overloaded to work efficiently. At most, you should schedule a professional appliance cleaning service to come once yearly, as doing so will keep your restaurant and all your appliances in tip-top shape.
3- Hire a Cleaning Staff to Assess Appliance Damage & Defects
If you manage to hire a commercial kitchen appliance cleaning company, have that same company check your equipment for any and all problems. A wire that appears frayed on a vent hood fan, for instance, could cause acrid smoke to fill your restaurant, which can, in turn, taint your food and put your customers off. By having your cleaning crew also provide regular inspections, you can keep your appliance maintenance ongoing while saving money on costly repairs.
4- Wipe Down Your Appliances Nightly
All of your kitchen equipment should be wiped down inside and outside. Make sure you use a powerful degreaser that cuts down on any films left behind. Any amount of grease can cause a fire, so pay special attention to your ventilation hoods and other components that tend to collect grease over time. Make sure you get up any moisture around the sinks and faucets by using a soft, dry rag, as that will prevent rust from collecting on your kitchen appliances. While you’re at it, unassembled your beverage machine faucets and soak them to prevent buildup. Finally, make sure you get up any grease from off the floor. While this isn’t technically appliance cleanup, it can also help prevent deadly fires.
5- Check All Equipment Monthly
Every month, you and your staff should check the refrigerators and freezers for cold air leaks, as well as cracks or punctures. You will also want to check your refrigerators, as well as your ovens, for any cracks or leaks. Check the hinges on your cooler and freezer doors, as well as your ovens, and test the suction on your ventilation hoods to ensure they are pulling the right amount of bad air out of your kitchen. While you’re at it, ensure you clean all the fan blades, including your make-up air fans, vent fans, and any others your restaurant employs. A commercial kitchen can use tons of fans, and each one should be cleaned and inspected at least monthly to ensure all components are working as they should.
6- Outsource Your Restaurant Equipment Maintenance & Repairs
At least once a quarter, we recommend hiring a company like APS-Hoods to come to your restaurant and inspect your vent hoods, ovens, refrigerators, and all other commercial kitchen equipment. This inspection will check your components for wear, which can be an indication that they may need to be replaced. Regular maintenance of your equipment will extend its life, but sometimes replacements do become necessary. A professional commercial kitchen cleaning and repair service like APS-Hoods can ensure you are always notified when equipment is faulty and needs to be switched out with the latest brand.
7- Schedule Service & Repair at Least Every Two Years
If you don’t opt for monthly or quarterly commercial kitchen equipment cleaning and maintenance, consider having a service arrive on your property at least every two years. This check can be as thorough as you prefer, including inspecting all your HVAC systems and ducting to ensure it’s free of grease and debris, as well as taking apart your ice makers and cleaning every internal component. These checks, once again, can save you loads in future replacement costs.
8- Get Replacements Based on Professional Recommendations
For a restaurant that runs optimally, you never want to base your equipment replacements on the look of an appliance or the cost. Instead, get a professional’s opinion based on your kitchen layout, your normal levels of business, and other important factors.
9- Replace Your Ventilation System Exhaust Belt Each Year
So that your commercial kitchen is always clean and fresh smelling, ensure you change out the exhaust belts of your ventilation system every year. This is a minor investment that can save you loads in the future.
10- Call APS-Hoods for Regular Equipment Maintenance & Repairs
If you operate a commercial kitchen, you may not know where to turn for monthly, quarterly, or annual cleaning and maintenance of all your appliances. Aps-Hoods is the qualified leader in commercial kitchen cleaning and repairs, and we serve both Denver, Colorado, for your convenience. Call now to schedule a free consultation.
Restaurant Cleaning Services: Most commercial kitchens resemble a shimmering chrome wonderland on opening day. All that equipment like your vent hoods gleaming in the fluorescent lighting invoke mouth-watering images of all the delicious meals set to be prepared for years to come.
However, it only takes a single busy shift for all your commercial kitchen equipment to become covered in grease, grime, soot, and debris. In some cases, scrubbing your kitchen equipment, and especially your ventilation hoods might seem like a useless act. The chrome will only get tarnished with every new lunch or dinner rush.
You might want to make the appearance of your commercial kitchen a priority, however, and particularly with regard to keeping a pristine exhaust hood finish. The finish of your vent hood matters, and not only for cleanliness.
Here are ten reasons why the finish of your vent hoods is of the utmost importance, and how to keep your commercial kitchen spotless and constantly performing for your loyal customers.
Call APS-Hoods for a free estimate on your Commercial Kitchen Hood Cleaning & Kitchen Exhaust Cleaning needs.
As a rule, you should strive to keep your exhaust hood finish and all associated equipment looking as clean as the day it was initially installed. The alternative is to allow your equipment to become caked with grease and other flammable materials, which could cause dangerous and expensive problems later.
There are two rules: First, after each shift, train your employees to protect their hoods, stoves, and other appliances from any contamination. This may require some elbow fat, but your equipment will be more durable and therefore perform better. The second rule is to use restaurant cleaning services periodically, which can improve the performance of your equipment, such as the opening day.
2. The Proper Chemicals & Cleaning Equipment
Ensure your staff is using the proper grease-cutting equipment that is safe to use on your equipment. Harsh chemicals and even abrasive equipment could cause scratches in your exhaust hood finish. While that sounds like more of an aesthetic issue, marring the finish can strip your hoods of any protective layers they were issued during the fabrication process. Speak to your vent hood manufacturers to determine which cleaners and equipment you should be using to keep your commercial kitchen clean.
3. Keep Your Exhaust Hoods Grease-Free
The finish on your commercial exhaust hood may look great, but looks can be deceiving. Ensure your staff consistently checks the grease filters and trap to keep your restaurant protected from back-ups and deadly fire. While keeping your exhaust hood finish gleaming is a priority, always check “under the hood” and keep the grease to a minimum.
4. Check the Drip Tray
While you are checking filters and your grease trap, make sure the drip tray isn’t overflowing. That drip, drip, drip could end up on the floor and in the unlikeliest of nooks and crannies. Errant grease can cause slips, falls, and fires. This is another vent hood cleaning component you must be mindful of when keeping your chrome equipment always looking its best.
5. Check the Exhaust Fans
Commercial kitchens need clean air in addition to grease and soot removal. Exhaust fans carry out both and need to work optimally in order to keep your staff safe and all prepared meals tasting delicious. While you are keeping the exhaust hood finish so clean you can see yourself in it, ensure your fans are working properly. Test the fans and call in a kitchen fan maintenance crew at the first sign of slow down, strange noises, or other issues. These are all indicators that your fans are not working properly, much to the detriment of your air quality.
6. Pressure Wash Vent Hood Exteriors
Your employees do not have to clean the air conditioning hoods to reduce grease. High-pressure hoses can be used to wash all food, oils, and fats (FOG) so that your system is thoroughly clean and suitable for inspectors. Many Restaurant Cleaning Services offer vent hood pressure washing services because nothing is more effective in contaminating your equipment.
7. Your Exhaust Hood Finish Matters to Inspectors
Speaking of inspectors, both the fire and health department professionals will be very interested in just how clean your exhaust hood finish happens to be. Of course, inspectors will also check the grease traps, ducts, and the cleanliness of your grease filters. This should serve as another reminder to keep your hood finish clean along with all components attached and underneath.
8. Test the Lighting & Wiring
Commercial vent hood cleaning should always involve a check of the associated electrical components. We mentioned checking your exhaust fans, but what about the wiring that keeps those fans operational? What about the lighting? Lighting that is out or bad lighting can also contribute to staff members missing grease or debris in out-of-reach places. Inspect the lights and wires while keeping your exhaust hood finish spotless to ensure optimal function, even during the busiest of times.
9. When the Finish Goes, Consider Replacement
In some cases, no matter how hard you scrub your ventilation hoods, nothing will get them clean. When that happens, it might be a good sign that you are due to a complete commercial ventilation hood replacement. Venting out the bad air is critical, as is keeping your kitchen free of grease and other flammable materials. A vent hood installation service can give your kitchen equipment the immense gleam you remember from opening day.
10. Maintaining Your Fire Protection System
Fire will tarnish your exhaust hood finish more than anything else. That is why you should always test your fire suppression equipment while you are engaged in kitchen exhaust cleaning. Whether you have an Ansul fire protection system, wet or chemical fire suppression equipment, you want to ensure that the slightest spark will be extinguished. With your fire suppression in good working order, you will keep your staff and customers safe and your business under constant protection.

Unlike a home kitchen, a commercial kitchen is a large space where food preparation and cooking processes go on for hours on end. As a restaurant owner, it’s your duty to keep the distinct areas of your kitchen properly cleaned, particularly the exhaust hoods. The purpose of the kitchen exhaust hood is to release smoke, heat, and smell and keep the kitchen atmosphere clean and safe.
The cleanliness of a restaurant is crucial both from the employees’ and the visitors’ point of view. If the kitchen environment is not well-maintained, the productivity of the employees will be impacted. Nobody would want to spend multiple hours in a kitchen if it exposes them to health risks. Visitors too want to sit and eat in a restaurant that is squeaky clean and free from any kind of smell. That’s why every restaurant owner is also bound by the law of their state to keep their restaurant properly maintained and guarded against safety hazards.
In case the safety codes are violated, the owner may have to face heavy penalties or shut down their restaurant altogether.
Before the cleaning task is performed, it’s a good idea to remain informed about the various parts of a commercial kitchen hood. An exhaust hood system consists of three main parts – filters, ducts, and fans.
Generally, an exhaust hood goes through a cleaning system before it exits the building. The exhaust hood, as the name suggests, functions to take the smoke, heat, and odor inside the kitchen out. It’s a ventilation system which also pulls in some fresh air from outside to keep the kitchen atmosphere clean and easy to work in. Broadly speaking, kitchen hood systems can be categorized into type I and type II. Type I exhaust hoods deal with grease whereas the type II exhaust hoods handle heat and odor. Together, they perform a great job of cleaning the kitchen atmosphere. The hoods are placed just above the fryer and burner in the kitchen.
Though a kitchen hood system comes along with two fans (for exhaust and makeup air), you can also install an additional fan on the roof over the exhaust duct system to speed up the ventilation process. The fans inside the hood are often linked with the building’s HVAC system. Just like the fans, the steel-made ducts are also two in number, one for releasing air and the other for makeup air. Other components of a commercial kitchen hood system include backsplashes, vapor proof lights, grease filters, and grease cups.
Commercial Kitchen Hood Cleaning
Cleaning the kitchen of a restaurant is a long, tedious process that can take up 4-6 hours. Abiding by the legal safety standards, you’ll be required to clean the hoods at least twice a year. But how many times your restaurant kitchen will need to be cleaned also depends on the current condition of your hoods. If you have a very busy kitchen and cleaning has been neglected for several months in a row, you may need the hoods cleaning done multiple times.
An experienced hood cleaning company can visit the distinct areas of your commercial kitchen and then suggest the best cleaning ideas. These service providers have the knowledge, expertise, and tools to clean the exhaust hoods of a kitchen to the bare metal and ensure efficient overall ventilation. The hood components that need cleaning include:
The filters of an exhaust hood system gather the most amount of grease and oil in the kitchen. That’s why they must be cleaned on a frequent basis. The code in your area will require you to get the hood filters cleaned once every month to avoid fire and safety hazards. As a responsible restaurant owner, you should never ignore cleaning the filters. In fact, you should get the hood filters cleaned every couple of weeks to remain fully safe from dangers.
The second most important part of a hood system is the ducts. After the filters, it is the hood ducts that accumulate the most amount of grease, particularly when the hood filters are not doing their jobs well. All the smoke and heat produced from cooking processes pass through these ducts, and so they need proper cleaning on a regular basis. professional kitchen hood cleaning contractors understand the value of ducts and clean this component professionally using the equipment and tools that are best suited for the task. If there are errors in the placement of ducts, the contractor can get that problem fixed as well for safety.
Both the fans and the motor are located inside the duct. While the ducts are being cleaned, the contractor will also check the fans and the motors to see if they are working properly. If the quality of the motor has degraded or it is not functioning to its fullest potential, the air quality in the kitchen will suffer. Therefore, it’s important that you get the fans and the motor serviced and maintained appropriately. This will improve the efficiency of the entire hood system.
Finally, the hood cleaning professionals will clean the other smaller components of the kitchen hood system. But there are many other things that cleaners need to do before they get started with the task. They follow an appropriately laid out procedure and a cleaning checklist to deliver the best results. Make sure you work with a reputed contractor and never skip the cleaning schedule.
Why You Can’t Ignore Commercial Kitchen Hood Cleaning
There are several benefits that a well-maintained and clean commercial kitchen has to offer. If you operate a restaurant, you should seek the services of a professional kitchen cleaning company to clean every distinct area of the kitchen. But one area which needs the most attention is the kitchen hood system. Therefore, you should make sure that every component of the hoods you have installed gets a spring-clean so that it functions to its maximum efficiency level. The top reasons you should get your kitchen hoods cleaned by a professional company on a regular basis are as follows:
An unclean kitchen is the breeding ground for harmful germs and bacteria. The build of grease and oil in the hoods can encourage the growth of these bacteria and ruin the quality of food in the kitchen. People getting sick from consuming contaminated food or drinks is a common problem. By giving your kitchen a routine cleaning, you can keep your food items safe and remove the risk of contamination. The high quality of foods translates to getting more customers.
If your employees are productive, it helps you get more done in less time and grows your restaurant business as a result. But an unorganized and smoky kitchen ruins productivity as well as jeopardizes the health of your staff. On the other hand, a clean and efficient kitchen exhaust hood system helps harmful particulates escape into the outside air and keeps the kitchen atmosphere clean and safe for the staff to work in and deliver their best performance.
A commercial kitchen remains exposed to a lot of heat for hours on end. Add to it the build-up of grease and oil in the exhaust hood. All of this together increases the risk of a potential fire in the kitchen. If a fire breaks out, it can do harm to both life and property. The expense of repair could be in millions. The most effective way to reduce these risks is to get the exhaust hood system of your commercial kitchen cleaned and maintained on a regular basis.
Since a commercial kitchen is such a busy place, you never know when things can go wrong. That’s why the law in every state has mandated for all large kitchens to follow a safety code. An untidy kitchen hood is a common reason for not clearing the inspection. If you land your restaurant in an emergency situation due to a lack of cleaning, you can end up paying heavy fines. You can avoid all these issues by keeping the exhaust hood system as well as other areas of the kitchen free from any kind of greasy buildup or contamination.
A vent hood system is not inexpensive to install. So, it deserves a good, proper cleaning on a regular basis too. The accumulation of grease and oil in the hood filters, ducts, and fans disrupt the smooth functioning of the hood system and reduce its longevity. If you just keep the exhaust hood cleaned, you can have it serve your needs quite efficiently for years in a row.
Most importantly, the maintenance of your commercial kitchen is directly related to your business growth. A safe and clean restaurant is equally loved by employees and customers. It speaks volumes about your values, concerns for people’s health and safety, and your brand. So, make sure your kitchen’s exhaust hood system is spick and span and works exactly as it should.
How Frequently You Should Get Your Restaurant Kitchen Hood Cleaned
While regular cleaning is always advisable, the number of times you should give your kitchen hood a cleanup depends on a number of factors. These include the size of your kitchen, volume of cooking, and frequency of inspection among others. You can talk to a professional kitchen cleaning contractor and find out what frequency of cleaning is best suited to your restaurant.
Depending on your unique requirements, you can set the frequency of the kitchen hood cleaning as one of these:
Commercial kitchens with solid fuel cooking operations develop a lot of greasy and oil buildup over a short period of time and need the most frequent cleaning. Such systems should be cleaned up every month.
If you have 24-hour food service in your restaurant, you definitely cook large volumes of food. In this case, you need professional cleaning at the interval of every three months. A quarterly cleaning frequency serves well both your inspection and maintenance requirements.
If the volume of your cooking is moderate and you have a sit-down facility in your restaurant for customers as well, you should get your exhaust hoods cleaned up at least twice every year.
There are many cooking centers that operate only for a couple of months every year. This means they cook a small volume of food. In such cases, cleaning the kitchen once a year should suffice.
Seek the Expert Consultation of a Kitchen Exhaust Hood Cleaning Company
A professional kitchen hood cleaning company has wide experience in addressing a variety of cleaning needs. They can tell you how often you should get the exhaust hoods of your commercial kitchen cleaned. Have a consultation with a reputable contractor and schedule cleaning for your restaurant. Once the cleaning up has been done, you can run your restaurant worry-free for the next six months. In addition, you can also check out the cleaning criteria set by the National Fire Protection Association to find out more about how frequently you should get your kitchen’s exhaust hood systems cleaned for safety against fire hazards.

Image SourceDenver, CO – The same exhaust fans that are keeping your commercial kitchen comfortable and protecting the area from overheating may also be creating air imbalance problems throughout your establishment. Because the size, design, door, and window placement of every building varies, the mechanism by which the atmosphere of your restaurant can best be corrected is most accurately established by an HVAC professional. They can provide what is called a Makeup Air service, which essentially replaces the air lost through hood fans with a special unit, which avoids some of the problems which present themselves when air from other areas of the home or building replace that lost air.
Call APS-Hoods for a free estimate on your Commercial Kitchen Hood Cleaning & Kitchen Exhaust Cleaning needs.
If the exhaust fan was not installed/incorrectly installed, or simply, if the makeup air from the fans is not enough to replace the air exiting from the stove area, negative air pressure can occur. Negative air pressure creates a sort of vacuum in your space, where windows and doors can shut suddenly, dust particles can settle fast onto surfaces or food, and whistle-like noises can also persist when air is let out or into space. These are very undesirable conditions for a dining or cooking area because of hygiene reasons as well as the disruption of ambiance this can create.
With negative air pressure sucking everything back into your space, the gasses that are supposed to be going out from your chimney will actually come back in, creating a health hazard. This can set off carbon monoxide detectors and threaten the safety of your patrons and employees.
Inefficiencies in Hoods
The exhaust hood, unaided by the sufficient amount of make-up air, will–in turn–not be able to process the amount of air it was designed to handle. Over time, you will notice a buildup of grease and grime on your kitchen surfaces. Also, unpleasant cooking and other smells will seep into all the space pockets of your building, including the dining areas, where patrons are trying to enjoy their food!
