The programme covered shower blocks and serveries in wings A, B and C. The shower areas varied between stainless-steel portal-style cubicles and tiled or painted construction, while the serveries combined plastic-lined surfaces, heavy-duty non-slip vinyl flooring and stainless-steel sinks and serving areas.
That variation mattered because the same cleaning method was not appropriate everywhere. The team also had to work within a three-hour evening window and complete one wing at a time, making sequencing and method selection central to the delivery plan.
Following inspection, wing A was allocated for manual deep cleaning using degreasers and scrubbing equipment. This allowed the team to work directly across the stainless steel, painted surfaces and heavy-duty flooring without introducing a steam-cleaning system where it was not required.
Wings B and C were treated differently. Their shower areas were suitable for DOFF steam cleaning, which uses high-temperature steam at low pressure. The method provided a way to tackle accumulated grime and loose, flaking paint while keeping water volumes relatively low.
In a washroom environment, adding unnecessary water can create its own operational problem. DOFF uses comparatively low volumes of water, reducing saturation and runoff when compared with conventional pressure washing.
For wings B and C, that combination of heat, low pressure and controlled water use allowed the team to clean the shower surfaces and remove loose paint while leaving the affected areas suitable for subsequent maintenance or redecoration where required.
The cleaning programme was carried out during the designated 6pm to 9pm window. Completing the wings individually allowed the team to keep the work controlled and aligned with the prison’s movement and operational requirements.
This was an important part of the project rather than simply a scheduling detail. In an occupied custodial environment, a technically suitable cleaning method still has to be deliverable within the restrictions of the site.
The targeted shower blocks and serveries across wings A, B and C were deep cleaned using the method selected for each area. In the DOFF-treated sections, accumulated grime and loose paint were removed, leaving cleaner surfaces ready for ongoing maintenance and potential redecoration where needed.
The programme also supported the original operational objective: improving the condition of high-use communal areas so that routine day-to-day cleaning could be maintained more effectively after the specialist deep clean.
