Commercial Kitchen Deep Cleaning

Whether you are running a hotel, restaurant, or catering kitchen, cleanliness should be a crucial part of your catering business. Public Health England estimate that restaurants account for 50 percent of foodborne outbreaks.

The outbreaks result from bacteria like Norovirus and Salmonella, which often breed in all the corners and cracks of prep areas, as well as on heavily used equipment. There may also be times when areas or appliances need to be cleaned more regularly than the recommended regularity.

    How does the catering industry define kitchen items?

    Moveable equipment

    These refer to the items that get into direct contact with food. For instance, trays, serving spoons, chopping boards, spatulas, and containers. Any utensils used during cooking fall under this category.

    Non-food contact

    These include washbasins, work surfaces, taps, walls, and door handles.

    Commercial Appliances and Equipment Cleaning

    Cleaning equipment and appliances are crucial in their maintenance. All your major devices and small ones such as microwaves, toasters, and coffee makers should be wiped down.

    Countertops and Hard Surfaces

    These two are a centre for bacteria growth. Since they are frequently used for food preparation, you should clean them regularly during the day.

    • Remove storage bins and items off the surface and then wipe them using a soft cloth and antiseptic spray.
    • Wear gloves every time and wash hands after sanitizing surfaces
    • When spraying, keep an 8 to 12 inches distance from the surface
    • When you are removing beverage spills or dried food, scrub your countertop using warm soapy water and a soft brush.
    • If you are cleaning tile surfaces, use special tile-based antiseptics that can grime off grout and remove bacteria.
    • Use soft scrubbing and scouring pads to avoid damaging surfaces
    • Launder dishcloths at 60 degrees temperature after cleaning kitchen surfaces. Rinse the cloths in warm water and store it in a bowl of sterilizer between uses
    • Always remove food stains while cooking and clean them regularly

    Cleaning an Oven

    Because of their versatile and heavy use, commercial kitchen ovens are centres for crumbs, grime, and other food by-products. The best way to tell when your oven needs a good, thorough cleaning is when it starts to smoke.

    • Remove the racks and wash them separately using warm water and non-toxic cleaner
    • Carefully remove burnt food by-products from the oven’s interior surfaces using a cloth. Get rid of all loose food remains.
    • Scrub what you can from food boil over and build-up using a pad or wire brush.
    • Using water and baking soda, make a paste and smear it on the remains residue
    • A few minutes after applying the paste, spray with vinegar and remove using a wire brush
    • Ensure the interior is clean with no residues by using vinegar and baking soda. Failure to do this results in contaminants, odours, and tastes.
    • Clean the door and exterior parts of the oven using warm water and non-toxic cleaner
    • Wipe the oven using a microfiber cloth for final touches

    Ovens are sensitive so, make sure you an accepted cleaning solution and follow the company procedures. Cleaning chemicals can be harsh on your hands. Thus, always ensure you wear gloves as well as any safety protections from both the manufacturer and your company.

    Cleaning Exhaust Hoods

    When it comes to cleaning duct systems, and canopy hoods are frequently the most ignored commercial kitchen areas. The exhaust hoods are responsible for ejecting heat, odours, and smoke from the kitchen area. It helps in preserving fresh air for staff and regulating temperature.

    • Make sure your kitchen crew conducts a regular external hood scrubbing as part of their systematic cleaning checklist.
    • Concentrate on the interior section to ensure safety and ideal food preparation.
    • Remove the filters from the hoods and wash them carefully
    • Scrub down the hoods themselves to remove soil or any baked-on grease

    • Clean your drains and piping for a neutral odour with the Greasepak module. It helps breakdown waste more effectively and keeps efficient functioning in pipes.

    Cleaning the Dishwasher

    Dishwashers must reach an 82.2 degrees Celsius temperature to offer exhaustive sanitation. Unless you can provide sufficient heat, always remember to separate equipment in the dishwasher.

    • Regularly, we are advised to do a pre-wash on utensils before cleaning them with a dishwasher. This helps in removing the baked-on stains. Failure to do this can result in clogging of the filter, hence affecting the dishwasher’s performance.
    • A poor dishwasher performance will result in cloudy tableware. If this continues with visible stains and marks after cleaning the filter, shift attention to your dishwasher.

    Cleaning Grills and Griddles

    Due to their significant uses in commercial kitchens, grime is accumulated on the surface, side, and backs of the grill and griddles. If they are handling high volumes, these appliances should be cleaned one a day, at best.

    • Pour a cup of clean fryer or cooking oil on a hot grill or griddle. Scrub in concentric circles using a pumice stone until its clean. Turn the grill off after scraping the cooking oil into the grease trap.
    • To break any persistent grease residues, pour seltzer water or a cup of soda water onto the warm grill's surface. Scrub it again as before.
    • Smear a half cup of vinegar on the grill’s surface and ensure it doesn’t pool. Using a rag, rub the grill in concentric circles and scrap the remaining grease for disposal. The acidity in vinegar is exceptional in removing stubborn stains.
    • Scrub the grill with a rag soaked in cooking oil. This ensures excellent decontamination and the grill re-seasoning. Make sure the sides and backs of the grill are scrubbed with a cloth. Use the above solution in case there are stubborn stains, scrub with steel wool, and use a rag to wipe it clean.

    • Use a dry cloth to wipe the interior clean

    Cleaning Floors

    If you want to create an enduring bright impression on your visitors, then make sure you have a sparkly floor. While maintaining sparkly floors makes them conspicuous, it also improves air quality. Even without using air fresheners, a well-cleaned area smells neutral.

    • By use of a professional floor cleaner, you experience instant results for elbow grease on the hard-to-reach places. This cleaner lets you preserve a healthy, natural shine of a freshly elegant floor.
    • Clean the gaps between appliances using a mop. You can harness a cloth to the mop’s handle to assure full coverage.
    • You should focus on maintaining the bathroom floors. When cleaning, you should emphasize on cleaner places first and finish on the most critical areas. Using this approach, you cut the spread of germs and ensure the toilet itself comes last.

    Cleaning Grease off a Kitchen Floor

    • Underneath appliances
    • Ventilation systems
    • Elevated shelves
    • Plenum chambers and filters
    • In-between walls and equipment
    • Fridge doors, shelves, and seals

    Touchpoints and Other Critical Zones

    Every day after service, sinks, countertops, and other substantial touchpoints should be cleaned. Always disinfect the countertops with a non-toxic cleaner, and use clean rags to wipe down carefully.

    The counters and preparation areas' backs, sides, and reachable bases should be scoured using non-toxic disinfectants to remove bacteria, viruses, and grime. Use warm water, non-toxic solution, sponges, or brushes to clean sink basins.

    Thoroughly clean knobs, faucets, and surrounding counter space or floors in closeness to the sink. Rubber and floor mats need to be cleaned with a mop and non-toxic solution, using warm water. Allow carpets to dry before placing them back into the kitchen to prevent injury and water transfer.

    To stress on exhaust hoods, the National Protection Association drafted a code relating to their installation and upkeep. If a commercial kitchen ignores their hood's regular cleaning, other than putting their employees at risk, they face the likelihood of high penalties. Also, it can cause a compulsory shut down when they are found to be substandard.

    In conclusion

    One of the top methods to save on your washing chemicals and to improve safety is using an autodose unit. It doses pre-measured quantities of chemicals which removes the problem of waste via overdosing. Its dispensed in sinks, buckets, and spray bottles.

    Saving effort and time on cleaning liberates your personnel to focus on the finer details.
