Oven Spring Cleaning

Ovens work hard in commercial kitchens. They are used throughout the day and are central to the kitchen’s success. But this heavy use means that deposits such as fats and carbon will soon accumulate unless the oven is cleaned regularly and properly. This can be a particular problem during busy periods such as Christmas and New Year when time is extra tight. Spring is the ideal time to give the oven a deeper clean now that the pressure is off a little.

Deposits are unsightly, at best. But under the wrong conditions, they can pose a food safety threat because they form a breeding ground for all kinds of unwanted bacteria. At the very least there is the risk of the deposits causing bad smells or contaminating any new food in the oven.

Spring cleaning can remove deposits of grease and burnt food from ovens.

Deposits can also limit the efficiency of the oven. This might happen if they cover heating elements, temperature sensors or vents. In each of these cases, the oven could work too hard. As a result it will use too much energy, which adds to costs. The additional stress on components can lead to expensive breakages and downtime that can affect the whole kitchen’s ability to operate properly.

In practice, of course, regular cleaning is best because it will prevent the build-up of any deposits that can cause problems. However, cleaning can be overlooked – or ignored altogether – in busy kitchens, no matter how well they are run.

Innovations Support Cleaning Improvement

As a market leader we work with our customers to devise, configure and implement fully-integrated solutions that are fine-tuned to their business and operational requirements. We have a unique ability to provide a complete set of products, tools, machines and services to support every aspect of a cleaning operation. 

This concept of a total solution from a single vendor is not new but it does require that we adapt to business and regulatory pressures and take advantage of new technologies. Innovation is a key requirement in many cleaning operations because it can support other objectives such as improving results or reducing costs.

But integration is about more than simply making existing products work with one another. Our approach is to introduce innovations and unique technologies across our portfolio to ensure customers can benefit from new ways of working while still dealing with a single market-leading supplier. 

When we were planning for the forthcoming Cleaning Show in London we decided to focus on ten of the many innovations that we have introduced in the decade since we last exhibited at the event:

TASKI swingobot 2000: the latest-generation “hands-free” scrubber drier is 25% more productive than the previous model. It gets on with automatic floorcare and liberates cleaning staff to focus on more important and value-added tasks.

Internet of Clean (IoC): our growing set of web-enabled and smart tools for this rapidly emerging business platform provide enhanced insight, oversight and management of cleaning operations.

Oxivir Excel and Oxivir Sporicide: a unique set of fast-acting, broad-spectrum infection prevention products with unique, patented Accelerated Hydrogen Peroxide as the active ingredient. They are effective against a wide range of pathogens including bacteria, viruses and yeasts.

Moonbeam3TM Disinfection Technology©: delivering powerful UV-C light to provide fast broad area disinfection of high-touch surfaces in hospitals and care homes in as little as three minutes when used in conjunction with normal daily cleaning and infection prevention processes. This offers facilities a completely hands, chemical and fume-free way to complement existing processes with safer high-performance disinfection.

SURE: a unique and innovative range of plant-based, 100 per cent biodegradable cleaning products covering all routine and daily cleaning requirements in kitchens and washrooms including personal care.

SmartDose & QuattroSelect: the portable SmartDose and wall-mounted QuattroSelect platforms are popular with cleaning teams who want to introduce highly sustainable ultra-concentrates into their operations. Both allow fast and accurate preparation of cleaning solutions.

TASKI swingo micro 2100: ideal for busy and confined areas, this high-performance scrubber drier has an ultra-compact design and tight turning circle. Its offset mechanism capability allows it to clean right up against a wall or obstruction to remove the need for secondary and detailed cleaning.

Twister by Diversey: an innovative set colour-coded floor care pads made from recycled plastics impregnated with billions of microscopic diamonds on the working side. They are ideally used with advanced TASKI swingo scrubber driers or rotary-disc machines and water alone to deliver excellent results while making floor care operations more sustainable.

TASKI AERO: this tub vacuum cleaner is believed to be the quietest and most energy-efficient machine currently available on the professional market. The four models in the range produce only 53dB(A) of sound and utilise just 585W of electrical power in standard mode yet produce as much cleaning suction as machines rated at 1000W or more. On energy savings alone, they can pay for themselves in under three years.  Also new is the TASKI AERO BP, a unique 3-in-1 solution that can be used as a backpack vacuum, tub vacuum or blower. The backpack vacuum is ideal for cleaning areas that are difficult to access with a conventional vacuum cleaner. It is among the lightest backpack vacuums, with its ultra-slim profile and high-quality rucksack material making it extremely comfortable to carry.

TASKI Trolley: modular trolley system with wide range of components and accessories that enable millions of potential configurations to support any cleaning operation. Additions to the range planned for 2019.

We’ll be posting separate blogs about each of these in the run up to the Cleaning Show.

As a business we commit considerable investment and resources to developing and supporting our products. With approximately 8,600 employees across 175 countries and 180 dedicated researchers in 20 advanced facilities, we offer unrivalled documentation, technical support, applications expertise and insight that helps our customers achieve the best possible outcomes.

Having such a comprehensive and innovative range means we and our customers can create highly focused solutions by choosing the very best products for the specific application and contract. Everything is designed and configured to work together seamlessly in order to deliver the maximum benefit in terms of performance, innovation, cost-control or any other criteria our customer specifies.

Complete Cleaning Solutions

Cleaning teams continue to face incredible pressure to deliver excellent results while introducing innovations, adding value, improving productivity and promoting sustainability without adding to costs. That can be a difficult set of criteria to achieve but we offer support with our unique ability to provide a complete set of products, tools, machines and services for every aspect of a customer’s cleaning operation from a single source.

As a market leader, we work with customers to devise, configure and implement fully-integrated solutions that are fine-tuned to business and operational requirements and deliver enhanced performance and value. The concept of a total solution from a single vendor is not new but it does require that suppliers adapt to business and regulatory pressures and take advantage of new technologies.

Sourcing from a single supplier offers a number of benefits for customers. Contract configuration and procurement processes are simpler because there fewer suppliers with whom to meet and negotiate. While this is self-evident many customers under-estimate the time and resources that can be involved with setting up major contracts.

Similar benefits arise during contract implementation because areas such as supply chains, training and compliance are less complex when dealing with fewer suppliers. While this can promote higher standards and greater consistency with reduced risk of incorrect deliveries it also means shorter and quicker communications channels should any issues arise. This is also the reason why support is usually simplified: there is less risk of being passed from one supplier to another when the underlying issue is unclear. Instead, the integrated supplier offers a single point of contact.

For their part, by offering an integrated solution selected from a wide set of products, suppliers can ensure everything is designed and configured to work together seamlessly and offer the maximum benefit in terms of performance, innovation, cost-control or any other criteria the customer specifies. We commit considerable investment and resources to developing and supporting our products. With approximately 8,600 employees across 175 countries and 180 dedicated researchers in 20 advanced facilities, we offer unrivalled documentation, technical support, applications expertise and insight that helps our customers achieve the best possible outcomes.

Integration is about more than simply making existing products work with one another. Innovation is a key requirement in many cleaning operations because it can support other objectives such as improving results or reducing costs. Our approach is to introduce innovations and unique technologies across our portfolio to ensure customers can benefit from new ways of working while still dealing with a single market-leading supplier. In this way we and our customers can create highly focused solutions by choosing the very best products for the specific application and contract. The alternative, of customers selecting different products from multiple suppliers, can lead to the complexity and resultant drawbacks previously mentioned.

Recent innovations from Diversey include: the latest-generation TASKI swingobot 2000 robotic floor cleaning machine; Twister by Diversey diamond-impregnated floorcare pads for use with TASKI floorcare machines and water alone; the IntelliCare hand care system with unique wall-mounted dispenser, the industry’s first automatic hybrid design with touchless and manual activation; Moonbeam3TM Disinfection Technology© for healthcare settings; the TASKI aero tub and backpack vacuum cleaners, among the quietest and most energy-efficient commercial machines on the market.

We have also added new Internet of Clean services such as IntelliLinen for laundries and IntelliDish for mechanical warewashing to build on our already extensive capabilities in this growing area. Cloud-connected services like these are increasingly being used to introduce new levels of insight, management and control to deliver improved performance and reduced costs.

All of these, and other new products, add to our portfolio and our ability to offer choices to customers that enhance the performance and outcome of cleaning operations while also strengthening their ability to win bids and secure new business. We will be highlighting many of these innovations and our total solutions capabilities at The Cleaning Show at London Excel, March 21-23.

Preventing Infections With Innovations

The fight against healthcare associated infections (HAIs) covers many areas but foremost among these are hand hygiene and surface disinfection. Studies suggest around 80 per cent of all infectious diseases are spread by touch[i]. This can be through personal contact or touching a contaminated surface. It follows that breaking this chain should help reduce the number of infections.

Healthcare cleaning teams now have access to a wider range of products to help them eliminate the pathogens that cause HAIs. These include innovative disinfectant formulations that are more effective, quicker and safer than traditional disinfectants complemented by advanced adjunct technologies such as UV-C light that can give the added level of protection against pathogens of concern.

Hand Hygiene

The link between hand hygiene and the spread of infections was established long ago. Yet there is still much to be done to change the behaviour of individual healthcare workers to optimise compliance with hand hygiene at the recommended points to improve patient safety. The best healthcare sites globally have reduced their infection rates to around five per cent through diligence and a rigorous application of best practice. In the UK the average infection rate is nearer to ten per cent.

The World Health Organisation promotes hand hygiene through a number of high-profile initiatives. Its annual Clean Your Hands Day, for example, was established in 2005 and has been a global success. This and related WHO programmes are based around the concept of a multimodal hand hygiene improvement strategy. This incorporates five components or building blocks including system change, training, evaluation, awareness and an institutional safety climate that lead to long-term and sustainable improvements. This framework is complemented by the WHO’s focus on the five moments of hand hygiene – the critical times when healthcare professionals should wash their hands: before touching a patient; before a procedure; after body fluid exposure; after touching a patient; after touching patient surroundings.

These recommendations can mean a lot of washing during a normal day. This is not only time-consuming but conventional soaps can strip natural oils which protect the skin, leading to an increased risk of damage through conditions such as dermatitis. Under these circumstances it is sensible to use an alcohol-based hand sanitiser that kills pathogens faster than soap without removing protective oils.

Whatever products are chosen, they must be available and ready to use whenever required. Dispensers should be situated conveniently to encourage regular and proper use. At the same time, they should ideally contain enough product to prolong the interval between refills and therefore minimise the risk of outages and reduce necessary restocking burdens.

Another way to encourage compliance is to monitor usage. While it is rarely desirable to monitor individuals, it is helpful to know how often a particular dispenser has been used and how much product has been consumed. Knowing how many times a dispenser has been used and comparing this with the number of patient contacts by the clinical and nursing team should give a reasonable indication of whether they are complying with agreed standards. If not, additional awareness and training can be provided and the subsequent change in usage patterns assessed.

Surface Disinfection

Surface disinfection is another critical aspect of infection prevention. It is vital to choose the right disinfectants to improve environmental hygiene in healthcare settings. However, not all disinfectants are created equally.

Healthcare cleaning professionals have traditionally chosen disinfectants with chlorine as the active ingredient (usually as bleaches) for cleaning hard surfaces.

While widely used, the drawbacks of these formulations are well noted in terms of effectiveness as well as safety and there seems to be a gradual shift towards safer, quicker and more effective disinfectants. Alternative formulations with Accelerated Hydrogen Peroxide (AHP) as the active ingredient offer numerous advantages with few limitations.[ii]

The key requirement from any disinfectant in healthcare settings is efficacy – to prevent the introduction of potentially harmful pathogens and infections. These can range from hospital associated infections such as MRSA and C. diff to infections common in any setting, such as influenza and Norovirus. Effective surface disinfection is especially important in healthcare because patients are likely to be frail and vulnerable.

It is important to select disinfectants capable of killing pathogens of concern. Problem pathogens, such as norovirus and C. diff., might not be killed by conventional disinfectants. Contact times must be realistically short so that any pathogens are killed before the surface dries. Disinfectants with long contact times may require reapplication to ensure pathogens are killed. This can be impractical, time-consuming and inefficient.

Disinfectants containing AHP are highly effective against a wide range of viruses, spores, yeasts, and fungi found in healthcare, including C. diff, MRSA, Norovirus, E. coli, and Pseudomonas aeruginosa. This broad-spectrum efficacy has been tested to the latest EN standards and submitted into the Biocidal Products Regulations (BPR) – a standard which all actives and disinfectants need to pass. AHP simplifies processes because just one product is needed – using numerous alternative products to provide the same level of performance adds unwanted complexity.

Disinfectants with AHP can be supplied in ready-to-use and ultra-concentrate formats. Depending on the specific formulation, these are effective against viruses, spores (including C. diff), yeasts and fungi in one minute or less, meeting demand for highly effective products with shorter contact or dwell times.

Traditional products containing chlorine are generally not as effective on spores and require significantly longer contact times. Products containing AHP have been tested and shown to kill viruses such as Norovirus in up to 30 seconds and the most persistent spores such as C. diff in one minute. Chlorine-based products can take up to 30 minutes. Aside from any productivity issues, they are only effective while wet which means efficacy will be lost if they dry within the specified contact time. Under normal conditions the much shorter contact times of AHP products are usually passed before they have dried.

Products containing AHP offer additional benefits that simplify day-to-day cleaning operations. With more cleaning taking place while patients are present, processes must be completed safely and efficiently, so as not to create an unpleasant environment or put patients at risk.

AHP degrades to oxygen and water alone shortly after use which helps make formulations containing it safer to use. Chlorine-based products are suspected of aggravating asthma and other respiratory problems, and forming chlorine compounds in the atmosphere. Another consideration is that some products containing AHP have no safety classification whereas chlorine-based products usually carry a hazard symbol.

Breaking down to water and oxygen alone means products with AHP leave little or no residue on surfaces, helping to promote the appearance of the area being cleaned. They can be used safely on a wider range of surfaces, including wool and other fabrics, with reduced risk of damage. Chlorine based products on the other hand will corrode or degrade many surfaces with regular or prolonged use. Nor can they be used as part of a microfibre system because they damage the material, severely restricting their disinfection potency.

The easier a product is to use, the greater the chance of cleaning compliance. Products should be accompanied by training aids to support members of diverse cleaning teams. Despite proper training, there are still cleaning and disinfection challenges that may arise. It is therefore important to measure performance to determine if additional training is necessary.

The variety of disinfectants has grown in recent years, as manufacturers have developed solutions for specific daily and problem-solving tasks. It is therefore important to match the product to the specific application. This optimises cleaning performance and reduces inefficiencies, poor results, and the need for repeat cleaning. Reputable manufacturers will provide advice on the most suitable products from their ranges to use in every situation. They should also be able to supply the documentation and evidence with independent test data to support product claims.

UV-C

While disinfectants offer healthcare cleaning professionals effective solutions in many situations there are times when additional measures are necessary or desirable. The latest technology to emerge uses powerful UV-C light to disinfect surfaces quickly and effectively[iii]. This represents a new hands-, chemical- and fume-free way to implement safer disinfection. It is particularly useful for so-called adjunct cleaning which is employed to complement or supplement existing processes and provide additional assurance that frequent-touch and hard-to-clean surfaces have been disinfected. Dr Deverick Anderson published a paper in 2017 that found using UV-C alongside traditional disinfectants reduced HAIs by 33%.[iv]

The infection-killing properties of UV-C have been known for some years and there are at least 40 scientific studies measuring either its biocidal effect on micro-organisms or the impact on HAI rates. UV-C kills pathogens by destroying the nucleic acids in their DNA. This disrupts the normal function of the cells which means they die. Any surface directly exposed to a sufficient amount of UV-C will be disinfected. One of the biggest advantages of UV-C disinfection is that large areas can be decontaminated very quickly without any additional intervention. Because UV-C disinfection is physical rather than chemical it means that there is much less chance of pathogens developing any form of resistance.

Despite these advantages, no cost-effective practical UV-C systems were available until recently for routine use in healthcare settings[v]. Now the devices used in hospitals produce powerful UV-C light at the optimum wavelengths to provide fast broad-spectrum disinfection. These devices tend to fall into two categories: for broad area and high-touch surface disinfection and disinfection of smaller, portable devices.

Systems designed for disinfection of broad areas and high-touch surfaces can be effective in as little as three minutes. This is more than twice as fast as fogging and almost twice as effective as traditional cleaning and disinfection alone in destroying the pathogens that cause healthcare associated infections. They are an excellent option for on-demand disinfection of high-touch surfaces throughout a hospital, including patient rooms, operating rooms and bathrooms. Such systems can also be used on patient care equipment, fixtures, keyboards, monitors, and workstations.

UV-C is at its most powerful when it hits a surface perpendicularly – at right angles – such as directly from overhead or square on to wall. Any deviation from this angle of incidence will diminish the power. In practice this means that at an angle of incidence of 45 degrees, the surface will only receive around 75% of the energy. At angles between 20 and 30 degrees the energy levels are reduced by around 60%.

Like all electromagnetic radiation, the power of UV-C also diminishes rapidly the further away a target surface is from the source because of the inverse square law. This means that the energy reduces fourfold (ie 2×2 or 2 squared) with each doubling of distance. Alternatively, the intensity at 2m from a light source is just 25% of the level at 1m. Using the same calculations shows that the amount of energy reaching a surface just over three metres (10 feet) from the source is one per cent or the original.

Systems delivering UV-C must therefore ensure the maximum amount hits the target surface to give the most powerful disinfection. One way to achieve this is to mount the UV-C sources on arms that can be positioned independently and pointed towards and set as close as possible to the target surfaces. This ensures more of the UV-C produced will hit the surface at right angles and at the minimum distance to give the best disinfection. When the light sources are mounted on a single, central column that is not easily repositioned, less of the UV-C produced falls on target surfaces perpendicularly and from further away. Either way this means the device will be less efficient.

UV-C systems for portable devices are designed to disinfect items such as tablets and smartphones. These are becoming more widely used in healthcare settings but they are often used by different members of the nursing or clinical team throughout the day. This means that they are not only frequent- or high-touch surfaces but they can also present increased opportunities for pathogens to pass from person to person. There is some evidence that people do not wash their hands after using these devices, or indeed clean the device itself.

As with any routine process, the use of these disinfection systems should be simple and quick to encourage their use. Items to be treated are placed in a secure box which contains the UV-C light sources, safely shrouded from the outside world. This means that they are always close to the items being disinfected for maximum effectiveness. Because items being treated are always close to the UV-C source these units provide extremely effective disinfection. Items can usually be disinfected in around 30 seconds.

Independent tests have shown that there can be an up to 5-log reduction in surface pathogens including MRSA, VRE, MDR-Gram negative, Norovirus and C.diff spores. This means that the number of micro-organisms is reduced by 105 times or by a factor of 100,000.

The power of UV-C to damage DNA and cells means that people would be affected too if they were exposed. Devices are supplied with fail-safe features such as remote control that prevent close-up activation and motion sensors that shut the unit down if anyone should approach too closely.

Hospitals and other healthcare facilities have a wider range of infection prevention tools at their disposal than ever before. The choice available means that there is greater flexibility to specify the right combination to meet infection prevention compliance and reduction targets in the quickest, simplest and most effective way that integrates with the facility’s other processes. The choices can be complex but leading cleaning and hygiene suppliers with experience in healthcare will be able to work with clinical, nursing and housekeeping teams to devise and implement robust infection prevention policies.

Making Cleaning More Sustainable

The cleaning industry has been through significant changes since we last attended The Cleaning Show, not least the accelerating trend towards sustainability. Our promotion of sustainable cleaning and environmental awareness goes back even further. And although it’s been given many names since 1923 (when our business was founded), sustainability has always been at our core. Our track record is demonstrated through leadership with the Carbon Disclosure Project, assistance with the Alliance for Water Stewardship and the Asean Corporate Sustainability Award, among many other achievements.


Our aim is to help create a healthier and safer world for everyone. We published our latest Annual Sustainability Report at the end of 2018.

At the same time, we announced a new “Facilitators for Life” strategy and goals. This new approach will help ensure we address key environmental, social and technological opportunities, including reducing greenhouse gas emissions, engaging in ethical business practices and decreasing our packaging footprint by 2025.

Achieving sustainable cleaning also underpins our product offerings. These should all help customers to save water, conserve energy, prevent waste, and increase safety. Our building care ranges, for example, are available as ultra-concentrates for use with dosing and dilution control platforms that enable safe, simple and consistent high-performance cleaning while minimising wastage, packaging and chemical miles. Our TASKI floorcare machines – scrubber driers, rotary disc machines and vacuum cleaners – offer class-leading performance in terms of lower energy, water and product consumption. Innovations such as the 100% plant-based SURE range provide our customers with further choices to demonstrate the highest levels of environmental responsibility.

In addition to greater awareness of sustainability issues across the board, few could have imagined a decade ago how technology-driven innovations would affect the industry and the daily lives of those working in it. As a global leader we have been at the forefront of this trend with innovations including its advanced TASKI swingobot robotic floorcare range and Internet of Clean services such as SmartView task auditing and IntelliTrail machine management. These utilise advanced technologies in new ways to support the aims and objectives of cleaning teams to collaborate and work smarter, more productively and more sustainably while reducing costs, improving outcomes and protecting brands.

We have a unique ability to support cleaning teams with a complete set of products, tools, machines and services for every aspect of their cleaning operation. This means we can work with customers to devise, configure and implement a fully-integrated solution that is fine-tuned to their business and operational requirements and delivers enhanced performance and value. The concept of a total solution from a single vendor is not new but it does require that suppliers adapt to meet the business and regulatory pressures and take advantage of new technologies. As a leading innovator across the industry, we introduce new products to maintain our full-service capabilities. In the past year alone we have added, among others, the Twister by Diversey diamond-based scrubber drier pads and the Moonbeam3TM Disinfection Technology© UV-light disinfection system to our comprehensive portfolio.

Something that was revolutionary just a few years ago can quickly become commonplace. In the past, this was true of ultra-microfibre and ultra-concentrates but today these are widely used by cleaning teams as a matter of course. Soon, innovations such as robotic cleaning, the Internet of Clean and UV-light disinfection will also become routine. You can see many of our latest innovations and learn more about how we can help you meet your sustainability objectives on Stand C37 at The Cleaning Show, Excel London, 21-23 March.
