What is Deep Cleaning?

December 13, 2021

Deep cleaning is a thorough, top-to-bottom clean of the areas your routine cleaning schedule doesn't reach. In a factory or warehouse that means behind and under machinery, high-level surfaces, drains, ducting and hard-to-access equipment, where dirt, grease and bacteria build up over time. It is done periodically, not daily, to reset hygiene standards and keep your site audit-ready. 


Since dirt and grime keep getting accumulated in corners, cleaning is a process that needs to be done regularly. But general maintenance cleaning will not cover every aspect of a factory as it would be too consuming to do so on a regular basis.


This is why deep cleaning is preferred - it goes above and beyond maintenance cleaning. Depending on your space and its needs, the frequency of getting deep cleaning done for your factory will differ.


Deep cleaning is an often overlooked, but important, part of maintaining the hygiene of food factories and manufacturing plants. It will decrease the risk of bacteria growth and pest issues due to the build-up of product residues in hard to access areas of the production equipment. 


Deep cleans should be done regularly for large commercial spaces (e.g., food factories, manufacturing plants, etc.) due to necessary health and hygiene precautionary measures. There are also machines that may need to be stripped and detail cleaned, and grease traps that need to be cleaned thoroughly. 


Deep cleaning vs regular cleaning

Regular cleaning keeps visible surfaces clean day to day. Deep cleaning goes further, stripping down equipment where safe to do so, cleaning at height and treating the build-up a daily clean leaves behind. Most sites need both: a routine schedule for daily standards, and planned deep cleans to stop problems building up between audits.


What does deep cleaning constitute?


The first thing to do when deep cleaning a factory is to identify all the hazards that are present in it. Hazards could include anything from chemicals to dust particles, or even bacterial growth. 


The next step would be to clean any contaminated surfaces by using industrial strength cleaning agents, scrubbers, or steam cleaners as necessary to get rid of any tough stains that if left uncleaned, could cause a health hazard. 


Deep cleaning also involves removing any build-up on the machinery and equipment of the factory that may have occurred over time due to lack of access which could impact the production process. 

It also entails sanitising floors with chemicals that will prevent microbial growth and remove odours from spills or other sources of unpleasant smells.

Advantages of deep cleaning


  1. It helps in maintaining the safety and cleanliness standards

    Every factory or manufacturing plant is legally required to maintain and operate under certain food safety standards. If these standards are not met, it could lead to issues for the business during inspections.

    Deep cleanings help your factory maintain the food safety regulations, and ensure that there are no problems that occur in the operation of the factory.

  2. It promotes a healthier environment

    A factory environment filled with dirt and micro-organisms could cause illnesses and diseases. These may not be very clearly visible, but they are often present on surfaces like doors and walls and in the wash rooms as well. If these substances come in contact with the skin, they could cause rashes and other unpleasant symptoms.

    When you get a deep cleaning service done, it eliminates micro-organisms, and thus promotes a healthier environment.

    A cleaner environment also decreases the chances of contaminating the food items or products produced, which is an added bonus. 

  3. It increases the lifespan of the machines

    Whether it is a food manufacturing or pharmaceutical plant, there are a large number of machines and equipment that are involved in the production of the products.

    Over time, if these machines are left uncleaned, it could not only lead to them getting spoiled faster, but it can also lead to the machines' disruptions in production due to excessive build-up.


    But when you get your factory deep cleaned, you are eliminating the risk of passively damaging the machines that are vital to production. Deep cleaning ensures that they are maintained properly and that they continue to run efficiently. 

  4. It increases air quality

    When there is a lot of dust present in a factory or plant, it can enter the lungs and cause allergies, and could worsen the symptoms of those suffering from asthma. 

    This is one of the reasons why a specialist commercial cleaning service such as Hygiene Group is often preferred for commercial cleaning services.

  5. It helps to get rid of bad odour

    No matter how regularly you do maintenance cleaning, there are some areas that could get left out during the daily cleaning routines. In some large manufacturing plants, the ceilings are often quite high, and unreachable to clean on a regular basis.

    Some food debris may be present in a corner somewhere that you may be unaware of. Because of these it is most often due to the growth of spoilage microbes such as bacteria that could start emitting a foul odour. It is important to make use of high-level cleaning equipment in order to effectively remove all odours.

    During a deep clean, every corner of the factory is cleaned, removing any particles that could be spreading bad odour, leaving your workspace clean and fresh. 


Deep cleaning can be time-consuming; however, it is the best way to go if you want your factory or manufacturing plant to be sparkling clean and hygienic.

Deep cleaning FAQs

  • What does a deep clean include?

    A commercial deep clean covers the areas missed by routine cleaning. That typically includes production equipment, floors and drains, walls and ceilings, high-level structures such as beams and ducting, and welfare areas like washrooms and canteens.

  • How often should a factory be deep cleaned?

    It depends on your sector, your production schedule and your audit requirements. Food and pharmaceutical sites usually plan deep cleans around shutdowns or ahead of audits. Our team can recommend a schedule after a site survey.

  • How long does a deep clean take?

    It depends on the size of the site and the areas included. A single production area can often be done in one shift, while a full site is usually planned across a shutdown period so production isn't affected.

  • What is the difference between deep cleaning and disinfection?

    Deep cleaning removes dirt, grease and build-up. Disinfection kills or suppresses bacteria and viruses on surfaces. A deep clean usually comes first, because disinfectant works best on a clean surface. See our commercial disinfection services.

  • Can deep cleaning be done without stopping production?

    Often, yes. We plan deep cleans around your production patterns, working nights, weekends or planned shutdowns where needed.

  • Do you provide deep cleaning across the UK?

    Yes. Hygiene Group is based in Birmingham and our crews work at food, pharmaceutical and manufacturing sites across the UK. Call 0121 451 3211 or get a quote.
