Commercial Oven Cleaning & Maintenance Tips

oven cleaning tipsNow that you’ve spent the money on your perfect commercial oven, you have to learn the importance and know-how of cleaning it after you’re done the cooking. No matter what precautions you put in place, spills are going to happen, but these helpful maintenance tips should help you keep it safe for the majority of the time.

General Oven Cleaning

Routinely cleaning your commercial oven can reduce the amount of residue and grime that can build up inside of it, allowing it to maintain a longer shelf life. Plus, this will also help your oven reduce the smell of burning food in the exterior racks. Instead, you’ll love the smell of your freshly cooked food. However, just like cleaning anything, it can take you weeks to a month to complete this step. But, once you fully clean it once, you only have minimal cleaning to do every week to keep your oven in tip-top shape.

Energy Efficient

Cleaning your oven can help increase its energy efficiency since it will now distribute heat better than before. This is mainly because a cleaner oven needs minimal energy to actually heat up and maintain its temperature.

Maintaining Your Oven Door

When you first get your oven, make sure the doors are closed so that there is no release of heat that can damage your food or your commercial oven in general. Look over your oven and see if there are any cracks or failing hinges that you need to fix to prevent heat from escaping while you cook. However, you should always gently close your door while using your oven, since slamming it can damage it for further uses.

Caring For Your Oven Seal

While caring for your oven, you should make sure that the seals are functional and not corroded. Since this will help retain the heat of the oven, it’s important that you keep it in shape and repair it whenever possible.

Tips For Cleaning Your Commercial Oven

A commercial oven lasts longer when cleaned regularly. The interior and exterior of the oven can get dirty pretty quickly, so it’s important that you keep on track with routine cleaning after your cook.


No matter how careful you are cooking, food is bound to boil-over, which can lead to a mess if you don’t take care of it quickly. Leaving boil-overs untouched until you do your routine oven cleaning may seem tempting, but the longer you wait the longer it will take to clean up. Not to mention, it could potentially cause irreversible damage to your commercial oven. If you have a boil-over, make sure you wait until your oven is cool before you start cleaning it up. Also, be sure to only use a damp cloth, you don’t want to put too much water in or on your oven since it can damage it that way too.


Debris can happen no matter how clean you cook. During your post-cook cleanup, make sure that any and all debris is cleaned from your ovens such as spills or crumbs. A large area to cover in your cleanup is where the oven door connects to the stove since that is one of the most commonly overlooked is that people neglect to clean. Plus, it can lead to corrosion and prevent the oven door from closing properly.

Oven Hood

Oven hoods are the quickest part of your oven to collect residue and grease from leftover cooking. Even if you don’t fry a whole lot, grease can still collect in your oven hood, which is flammable and a fire hazard in any kitchen.

Grease Pans and Exhaust Filters

When you need to clean the canopy hood above your commercial oven, you first need to remove the grease pans and exhaust filters, as well as disposing of any grease they collected into the trash. You should then wipe down these parts with a wet paper towel to remove any debris or excess grease.

Next, you should wash out these parts with warm, soapy water and let dry. When cleaning off the hood, you should use hot, soapy water with a nylon scrubber to remove and grease or debris. Make sure that you properly wipe down all the pipes inside the good and wipe dry, since water can cause rust which will damage your oven.

Maintenance Tips For Specialized Ovens

Convection Ovens

Convection ovens are very common in commercial kitchens, so you can follow most of the same rules above. However, be sure to pay special attention to cleaning the intake fan. This may come with a few challenges. Food particles can become stuck in the fan, the oil levels can be low, or there may be a loose hinge. You should remove the intake fan every week and clean it on its own. Double check the hinge to ensure that it is functioning properly as well.

Conveyor Ovens

A lot of the parts of a conveyor oven must be removed and cleaned on their own to ensure a proper cleaning. Your list of parts to clean should include the crumb trays, conveyor belt, draft diverters, and more. Though most people recommend cleaning these parts every day, plenty of restaurants perform weekly cleanings. Read your instruction manual to get more specific instructions and recommendations for your unit.

Accelerated Cooking Ovens

These ovens use a combination of grilling, convection, and microwave functionality in order to provide fast cooking times. These ovens are typically used in kitchens that see a high volume of orders. Because of their increased functionality, they also require additional maintenance. One of the main problems these ovens face is burnt on food. Because of the high heats this oven uses to cook, food tends to splatter more, too. Be sure to clean up messes as they occur and do not let food build up. These messes can lead to energy issues, smoking, and flavor changes.

Combination Ovens

Combination ovens function like a convection oven, traditional oven, and a steamer. Because they have so many additional features, they also require more maintenance. You will need to clean your oven as you would for each of its functions. Similar to a convection oven, you will need to remove the fan and clean it often. Like a traditional oven, you should remove and clean the racks every day. You will also need to take care of spills, food debris, and other standard oven issues, too. With the steamer, you will need to empty it and delime it often.

Deck Ovens

You will need to take special care when it comes to your deck oven. Dough can get stuck on the surface and create stains and clumps. To remove any food particles, turn the heat up high until all particles turn into ash. Then, after the oven cools, use an oven brush to sweep up the ash. Stay away from liquid cleaning solutions as they can cause the deck to crack.

Rotisserie Ovens

These ovens collect a lot of grime and grease throughout the day. The spits and rotors also tend to become very dirty. Though they may seem complicated, rotisserie ovens are actually quite simple to clean. When the day is done, remove the rotors and spits and soak them in a cleaning solution. You can then wipe down the inside of the oven with a cleaning solution or you can steam clean it.
