Commercial Food Factory Cleaning

Client: Commercial food factory, Liverpool

Project: APT was asked to look at solutions to carry out industrial deep cleaning within a food manufacturing plant to deal with heavy build-up of hardened oil and grime that had built up over time on high level surfaces throughout one of the key production areas. These areas were difficult to access or not accessible to their internal cleaning operators. The food company had been unable to find any local companies who could offer safe commercial cleaning solutions to carry out the high level deep cleaning that would meet with their strict health and safety programmes.  

The Challenge

A recent internal audit identified the potential risk of contamination to some of the processing areas. The auditors listed a programme of improvement areas and contacted several commercial and industrial cleaning companies to look at the deep, high level cleaning. Some of these companies did not respond or declined to quote for the works due to the nature of the work and access difficulties.  

APT’s Solution

APT surveyed the production areas and recommended cost effective cleaning options to the client for commercial deep cleaning equipment and the high level heavily soiled surfaces of production machinery.  

After agreeing a health and safety plan and suitable work schedule to minimise disruption to production we used our own commercial cleaning equipment, hiring in some specialist lift access platforms.

After agreeing a health and safety plan and suitable work schedule to minimise disruption to production we used our own commercial cleaning equipment, hiring in some specialist lift access platforms.

We used APT Powermax 2020 which is a food safe, heavy duty degreaser product ( to clean and degrease all high level surfaces, under roof ceiling panels, all steel work, extractor, pipe work, cabling and ducting. We set about cleaning the hot oil frying equipment after discussing with the company’s operatives to understand the existing plant cleaning methods. We used our own, more effective degreaser and carb cleaner ( to remove the heavy build-up of black carbon deposits and burned hard oils.

The client requested that we work in conjunction with their new internal hygiene team to support the cleaning which we welcomed. Whilst on site we trained them on how to use the Powermax 2020 degreaser and sanitise all the plant machinery and equipment as part of their regular maintenance cleaning programme. We later supplied them with the tools and equipment to carry out effective cleaning.


Whilst on site we assisted and carried out an assessment of current cleaning methods and products used and we were then able to offer the client several improvement options to raise the standard of hygiene and reduce labour intensive cleaning.

One of the proposals was made after liaising with the client’s plant engineers and assisting the client’s operatives to deep clean the heavy oil frying equipment. Their current methods included the use of heavy caustic chemicals and operatives were unable to achieve satisfactory cleaning of the frying and extraction equipment. We introduced APT’s Metasoak, an aluminium safe cleaner, to degrease and decarbonise both the steel and aluminium metal surfaces. The proposal for the ongoing use of Metasoak heavy duty degreaser was approved and implemented by the Technical Officer.

We offered further improvements in cleaning methods and adaptations to some of the equipment to allow some of the panel to be made demountable so they could be cleaned automatically.

Another proposal was to allow for manual, low pressure, heavy steam cleaning of intricate surface areas. This method would further reduce safety risk to operatives and allow a more effective and quicker deep clean which would result in large annual labour and chemical cost savings.

The list of improvements, application and equipment adaptions were all passed to the technical and hygiene officer for approval and implementation. Several other smaller key proposals were made and are part of an ongoing improvements programme.    

What Our Client Said

“I was very impressed at the level of knowledge and understanding of our production processes and their interest and proposals offered to improve cleaning standards throughout the production areas. This I found was very unique, they did not just turn up and carry out the cleaning and leave we. We found this information invaluable for improving our internal cleaning programme.  

The APT team approached the difficult cleaning tasks with great professionalism and they kept my operational staff and I updated throughout the project. Their operatives had no issue in working and assisting my hygiene team and offered them help and training to use both chemicals and materials. They were extremely helpful and assisted with several improvement measures which we will now be implementing going forward. The plant managers and I are very confident that APT will be of great help to us in all future projects and we will be recommending them to carry out regular and ongoing deep cleaning of our plant.

Thank you again APT”

K Render Cleaning & Algae Removal at Leisure@Cwmbran

Case Study Image - K Render Cleaning & Algae Removal at Leisure@Cwmbran

The k render facade of the Leisure@Cwmbran complex had become badly stained with airborne pollutants and algae/moss growth which was unappealing to users of the centre. The client set out an enhancement programme to improve the aesthetic of the centre which included exterior cladding cleaning to remove algae from the k render, remove surface staining and treat and kill moss from all pedestrian pathways.  It also included cleaning of stone and masonry to remove graffiti and effervescence staining. 

The timescale provided by the client was 13 days.
