Cleaning Commercial Ovens: A Practical Guide for Cleaning Professionals

Commercial oven cleaning remains a key concern for UK food businesses. The FSA’s Local Authority Performance Update shows that formal enforcement actions for food hygiene increased (showing a rise in compliance issues), which implies hygiene failures remain a concern across the sector.  In busy commercial kitchens, ovens are often the hardest appliances to keep clean. For cleaning professionals and facilities teams, knowing how to clean commercial ovens properly is essential for safety, compliance, and long-term performance.

Commercial ovens work harder than almost any other appliance. As a result, grease, carbon, and burnt food build up quickly. If this is not controlled, it can affect cooking results, hygiene scores, and even fire safety. This guide explains best practice for commercial oven cleaning and how to choose the right professional products.

Why Commercial Oven Cleaning Matters in Professional Environments

Commercial ovens are used daily, often for long hours. Over time, grease and carbon deposits build up on internal surfaces, doors, fans, and seals. This is not just a cosmetic issue.

Dirty ovens can cause uneven cooking and longer cooking times. They can also transfer burnt flavours to food. More importantly, built-up grease increases the risk of smoke, odours, and fire. From a compliance point of view, ovens are a key focus during Environmental Health Officer inspections.

For cleaning contractors and in-house teams, regular oven cleaning supports higher hygiene ratings. It also helps kitchen staff work more efficiently. Most importantly, it extends the life of expensive catering equipment.

Heavy-Duty Oven Cleaners for Deep Cleaning

When ovens accumulate thick layers of carbon and baked-on grease, a deep clean is required. A heavy-duty cleaner like Suma D9.12 Auto Oven Heavy Duty Cleaner 5LS is ideal for scheduled, intensive cleans.

These products remove deep carbon deposits, grease and burnt-on food residue effectively. They are best used when ovens can be taken out of service for a short period, perhaps between services or during quieter times. Using a strong oven cleaner significantly reduces scraping and manual effort, while improving consistency and saving time.

However, it’s important to follow COSHH guidance: ensure staff wear suitable PPE, provide adequate ventilation, and allow correct dwell time. Once cleaning is done, thoroughly rinse all surfaces before reintroducing food or switching the oven back on.

Maintenance-Level Oven Cleaners for Regular Use  

For kitchens operating at high volume, frequent deep cleans aren’t always practical. Instead, a maintenance approach using a gentler cleaner such as Pro Line Oven & Grill Cleaner helps manage grease and food residue before it becomes a major problem.

This type of cleaner is effective on baked-on grease and food residues yet is more suitable for regular or weekly use. It helps maintain a clean oven interior between deep cleans, which makes subsequent intensive cleaning easier and faster. It’s also safer for staff to use more frequently, and helps kitchens maintain hygiene standards during busy periods.

Oven & Grill Cleaner for Routine Surface Cleaning

For light cleans, maintenance tasks, or smaller ovens, products like BioHygiene Oven & Grill Cleaner 750ml are very useful.

This cleaner is designed to tackle grease, oils, and food residue on oven surfaces, grills, hobs, and related kitchen equipment. Its formula is less harsh than heavy-duty cleaners, making it a good choice for regular upkeep. For kitchens that want to keep oven interiors in clean condition throughout the working week, especially between major cooks, this type of cleaner reduces odours, improves hygiene, and makes cleaning less labour-intensive.

The Right Equipment Makes Commercial Oven Cleaning Safer and Faster

Using the correct cleaning chemicals matters. However, the equipment used alongside them is just as important. In commercial kitchens, poor tools can slow the job down and increase risk.

Professional oven cleaning should always start with gloves. Strong oven and grill cleaners can irritate skin quickly. Gloves protect cleaners and allow better control when working on hot spots like oven doors, racks, and seals.

Next, non-scratch sponges & scourers should be used. Stainless steel ovens scratch easily. Scratches trap grease and carbon, making future cleaning harder. Abrasive pads may seem faster at first, but they damage surfaces long-term. Using the right pad keeps ovens smoother and easier to maintain.

After cleaning, cleanmicrofibre cloths should be used for rinsing and wipe-downs. Rinsing removes chemical residue and prepares surfaces for food use. Using fresh cloths prevents re-contamination and supports food-safety standards.

Compliance, Hygiene Standards and Long-Term Equipment Care

Regular, professional oven cleaning supports hygiene compliance. Clean ovens help meet food safety standards and assist clients in passing audits or inspections. They also help prevent costly breakdowns or maintenance issues caused by grease build-up.

For cleaning contractors, offering a comprehensive oven-cleaning service adds real value to clients. It reduces kitchen downtime, improves cooking consistency, and supports long-term equipment life. Using trusted appliance-care products shows clients that you take hygiene seriously and are committed to quality.
