The Ultimate Guide to Kitchen Deep Cleaning: Tips for a Hygienic Space

A pristine and hygienic kitchen is the backbone of any successful business in the food industry. Commercial kitchens, in particular, demand rigorous cleaning to ensure the highest standards of hygiene and compliance. In this comprehensive guide, we delve into the importance of commercial kitchen deep cleaning and its profound impact on maintaining a sanitary space and offer practical, step-by-step tips for achieving a thorough cleaning.

Why Commercial Kitchen Deep Cleaning Matters:

With over 25 years of expertise in the cleaning industry, Fluid Hygiene recognises the critical role deep cleaning plays in a commercial kitchen. The implications of neglecting thorough cleaning in this space can be far-reaching. It not only affects the health and safety of customers but also has regulatory and financial repercussions.

1. Ensuring Food Safety:

  • A clean kitchen is fundamental to preventing foodborne illnesses. Bacteria, pathogens, and contaminants thrive in unclean environments, posing a significant consumer risk.

2. Compliance with Regulations:

  • Regulatory bodies like the Food Standards Agency (FSA) set stringent hygiene standards for commercial kitchens. Regular deep cleaning is essential for compliance, avoiding fines and business closures.

3. Equipment Longevity:

  • Regular deep cleaning extends the life of kitchen equipment. Grease and grime buildup can lead to malfunction and breakdown, resulting in costly emergency repairs and replacements.

4. Enhancing Operational Efficiency:

  • A well-maintained kitchen promotes smoother operations. Clean surfaces and organised spaces contribute to an efficient workflow, reducing the risk of accidents and optimising productivity.

Step-by-Step Guide to Thorough Kitchen Deep Cleaning:

Fluid Hygiene’s commitment to excellence is reflected in its approach to kitchen deep cleaning. Here’s a step-by-step guide inspired by their industry-leading practices:

1. Preparation:

  • Remove all items from countertops and surfaces. A tidy space clear of clutter will speed up the deep cleaning process. 
  • Ensure proper ventilation by opening windows or using exhaust systems.

2. Equipment Inspection: 

  • Inspect equipment for signs of wear and tear.
  • Schedule repairs or replacements as needed.

3. Degrease Surfaces:

  • Use commercial-grade degreasers to break down grease and grime on surfaces, including ovens, stovetops, and hoods.

4. Appliance Cleaning:

  • Disassemble and thoroughly clean appliances like ovens, grills, and fryers using appropriate professional chemical solutions.
  • Pay attention to extract filters, which often accumulate significant grease deposits. Your kitchen extraction system needs very close attention due to the high fire risk. 

5. Sanitisation:

  • Use food-safe sanitisers to disinfect countertops, cutting boards, and other food preparation areas.
  • Pay special attention to high-touch areas.

6. Floor Cleaning:

  • Sweep and mop floors, ensuring the removal of debris and spills.
  • Consider using anti-slip mats in high-risk and wet areas.

7. Deep Cleaning Refrigerators:

  • Empty and clean refrigerators, removing expired items.
  • Check and clean coils to maintain optimal efficiency.

8. Grout and Wall Cleaning:

  • Scrub grout lines and walls to remove accumulated dirt and stains.
  • Consider resealing grout for added protection.

9. Professional Assistance:

  • Periodically engage professional cleaning services, like Fluid Hygiene, for an in-depth and specialised deep clean.

10. Regular Maintenance:


A hygienic commercial kitchen is non-negotiable in the food industry. Following this ultimate guide, inspired by the practices of industry leaders like Fluid Hygiene, ensures compliance with regulations and creates a safe and efficient space. Regular deep cleaning is an investment in the longevity of equipment, the health of customers, and the success of your business.
