Why Cleaning Your Conveyor Pizza Oven Matters
In a fast-paced UK takeaway or restaurant kitchen, conveyor pizza ovens are one of the most essential and heavily used pieces of equipment. They keep service moving quickly by producing evenly cooked pizzas with minimal manual handling. But when these ovens aren’t cleaned properly, they become one of the biggest problem areas in your kitchen — leading to poor food quality, breakdowns, and even failed inspections.
Build-up of cheese, grease, and crumbs can clog vents, slow down the belt, and cause uneven cooking. Over time, these residues harden, carbonise, and become almost impossible to remove without harsh chemicals or professional cleaning. Worse still, the risk of smoke, burnt food, or even fire increases dramatically. Keeping your conveyor pizza oven clean is about more than looks — it’s a matter of safety, efficiency, and food hygiene.
Whether you’re running a small independent pizza shop or part of a growing franchise, your cleaning schedule needs to prioritise this equipment. The good news? With the right habits, it doesn’t have to be complicated.
How Often Should You Clean It?
The frequency of cleaning depends on usage. For high-volume takeaways in the UK — especially those operating late into the evening — certain cleaning tasks should be performed daily, while more thorough cleans can be scheduled weekly. If you’re cooking greasy or cheesy pizzas consistently, you may even need to clean more often than that.
Daily: Surface wipe-downs, emptying crumb trays, and clearing spills. The focus here is on quick actions that prevent residue from hardening overnight.
Weekly: A deeper clean involving dismantling parts like the conveyor belt, scrubbing chamber walls, and vacuuming ventilation areas. Some sites choose to clean twice per week depending on output.
Monthly: Full disassembly, inspection for signs of wear, and possible servicing of motor or fan components — often done in-house or by a technician.
It’s a smart move to keep a visible cleaning rota near the oven. That way, everyone on your team knows what’s been done and when. It’s also a good way to show EHO inspectors that you’re staying on top of maintenance.
6 Most Important Places to Clean
1. Conveyor Belt
The conveyor belt is the heart of the oven — and often the dirtiest part. Bits of cheese, flour, and toppings fall onto it with every pizza that passes through. Over time, these particles build up and begin to burn, causing smoke and impacting taste. Worse, the build-up can affect the movement of the belt, leading to jams or uneven speeds.
Remove the belt carefully, following the manufacturer’s instructions. Soak it in hot water and a degreasing solution that’s safe for stainless steel. Scrub each section thoroughly with a stiff brush. Allow to dry completely before reinstalling. Cleaning the belt weekly will keep it running smoothly and prevent long-term damage.
2. Crumb Trays
Crumb trays are designed to catch food debris that drops through the belt, and they fill up quickly. If left for more than a day or two, they’ll not only start to smoke, but also pose a fire risk. In fact, many kitchen fires in pizza shops originate in neglected crumb trays filled with burnt grease and crumbs.
Empty and wash these trays daily. Use a scraper or putty knife to remove burnt-on bits, then clean with warm, soapy water. Make sure to dry them before putting them back to avoid rust, especially in older ovens.
3. Air Vents and Intake Covers
Conveyor ovens rely on airflow to cook food evenly. When vents or intake covers are blocked, the oven begins to overheat, temperatures become inconsistent, and fans can start to strain. This not only affects cooking quality but also puts stress on internal components.
Once a week, wipe down all external vent covers with a damp cloth and food-safe degreaser. For internal vents, use a vacuum or air duster to remove crumbs and dust. Be careful not to push debris further inside — always work from the outside in, and follow manufacturer guidelines.
4. Cooking Chamber Walls
Cheese, sauce, oil, and toppings often splash against the internal walls of the cooking chamber. This sticky grime quickly burns into carbon, which not only smells terrible but also affects heat circulation. Some chefs even report ‘ghost flavours’ appearing in pizzas when the oven walls haven’t been cleaned.
Once the oven has cooled completely, spray the inside walls with a non-abrasive, food-safe oven cleaner. Let it sit for 10–15 minutes before wiping clean with a soft cloth. Avoid wire brushes or harsh scourers — they can damage insulation panels and cause long-term issues. Repeat weekly or as needed based on usage.
5. Drive Motor & Fan Housing
Although these are not parts you clean daily, they play a vital role in the oven’s performance. Dust, grease, and food particles that make their way into the drive motor or fan housing can cause overheating, loss of power, or mechanical failure. In the worst cases, the oven may shut down mid-service.
Switch off and unplug the unit before performing any cleaning. Use a soft brush or vacuum to remove dust, and inspect for signs of wear or damage. If you’re unsure, schedule a service call — especially if the oven is making strange noises or smells unusually hot during use.
6. Exterior Panels and Handles
First impressions matter, especially in open kitchens. If customers or staff see a greasy, grimy oven, it reflects poorly on your standards. Plus, regularly cleaning exterior surfaces helps prevent long-term staining and corrosion — particularly in coastal UK areas where humidity is higher.
Use a stainless-steel cleaner or a diluted vinegar solution to wipe down panels, handles, and any digital displays. Pay close attention to crevices where food can hide. Clean these areas daily or during each shift if the oven is used heavily.
Ongoing Maintenance & Troubleshooting
In addition to cleaning, it’s a good idea to create a monthly maintenance checklist. This might include checking belt tension, inspecting gaskets, and testing temperature calibration. If your oven’s cooking time starts to fluctuate, or if pizzas come out unevenly, it’s often a sign that deeper cleaning or service is needed.
Keep a record of repairs and servicing dates. This helps spot recurring issues and can be a valuable tool when deciding whether to repair or replace an aging oven. Also, stock a few spare parts on-site — things like crumb trays, belts, or heating elements. That way, you’re never caught short during peak hours.
Final Thoughts
Your conveyor pizza oven works hard. It runs for hours at a time, often seven days a week, and delivers hundreds of perfectly cooked pizzas. But without proper care, even the best oven will begin to struggle. Cleaning is a core part of your kitchen’s workflow — not something to skip when things get busy.
By focusing on these six key areas, building daily and weekly cleaning habits, and training your team properly, you’ll protect your investment, maintain food quality, and keep inspectors happy. Don’t wait for burnt smells or uneven pizzas to alert you — stay ahead with a strong cleaning routine, and your oven will reward you with years of reliable service.
