Brasserie Blanc Milton Keynes: Reducing Cleaning Frequency and Solving Access Challenges

- Cleaning frequency reduced from 3 months (100 days) to 6 months
- Site time reduced from 2 nights to 1 night per visit
- Inaccessible ductwork fully remediated without manual cleaning
- Continuous TR19 compliance maintained across entire system
- Labour costs and visit frequency significantly reduced

Brasserie Blanc Milton Keynes operates a large kitchen extract system that originally required cleaning over 2 nights every 3 months due to its size. The system also included sections with restricted access - ceiling voids, manifold ductwork at difficult angles and vertical risers with limited access panels. Manual cleaning in these areas was extremely difficult, creating compliance challenges.

The Challenge

The large extraction system required frequent, labour-intensive cleaning to maintain TR19 compliance. Cleaning took two nights every 100 days - causing significant disruption and high labour costs. Worse, parts of the system were in ceiling voids and restricted spaces where manual cleaning was impossible. Manifold ductwork (200mm x 1000mm) could only be reached at arm's length from ceiling hatches. CC10-size access doors provided no real cleaning access. Vertical risers had access panels every 3 metres, leaving large sections unreachable.

The Solution

Ecofix was installed throughout the extraction system with specialized remediation programming for inaccessible sections. Canopy spray bars dose detergent 5 times daily during operations. Spigots adjoining the canopy receive regular detergent and bio dosing. Manifold ductwork (1-3 metres) uses detergent and bio additive to stop fatty deposits binding with surfaces.

For inaccessible sections, Ecofix dosing was concentrated to remediate large areas of unreachable ductwork. The delivery system was upgraded, with nozzles repositioned each visit to improve coverage and remediate full sections. Dosing runs during peak kitchen operations when airflow is maximum - the air disperses the dose and carries waste to the next bend or transition where it collects. Once sections are fully remediated, Ecofix is reprogrammed to standard settings for ongoing compliance.

The Results

Cleaning frequency extended from 3 months to 6 months, with site time reduced from 2 nights to 1 night per visit. Pre-clean inspections show minimal contamination buildup across all sections. Canopy surfaces resist grease deposit buildup despite heavy use. Spigots, manifold ductwork, and midway sections remain in non-cleanable states with minimal biomass waste between services.

The inaccessible ceiling void ductwork at Milton Keynes, which had never received manual cleaning, was fully remediated back to compliant standard through Ecofix dosing alone. Similar success was achieved at Brasserie Blanc Chancery Lane, where 200mm x 1000mm manifold ductwork in restricted ceiling voids became compliant without manual access. Vertical riser sections unreachable between 3-metre access panels were remediated over time through continuous dosing.

Key Benefits

Ecofix solved both operational and access challenges for Brasserie Blanc. The 50% reduction in cleaning frequency and single-night visits deliver huge labour cost savings. More importantly, the system resolved compliance issues in areas where manual cleaning was impossible - ceiling voids, restricted manifold ductwork, and vertical riser sections between access panels. The remediation capability demonstrates how automated grease management maintains compliance in complex systems with difficult access.
