How to Clean a Commercial Deep Fryer

Commercial Deep Fryer Cleaning

No one necessarily likes cleaning kitchen supplies, but it can be even more of a hassle to attempt and clean something massive such as a traditional deep fryer. Whether you’ve had it for years or this is your first one, it’s important to know what you’re getting into, not to mention how to best keep it clean and efficient. Keep reading below for the step by step on how to clean a commercial deep fryer properly, plus get answers to some commonly asked questions.


Beginning with an oil free tank, you will want to open your fryer and set your solid-state thermostat to 250 degrees. F You will then want to turn the on/off switch 5 times: on, off, on, off, and on once again. This will begin the “boil out” or clean-out procedure.

If you’re using a computer control, you will press the thermometer button, and then pressing 2-1-2, which will show the BOIL display.

Once your fry tank has begun to boil, you take the fry cleaner and pour it into the tank. You’ll want to let the tank boil with the cleaner inside of it for about 5 minutes. Only after that should you go in with a brush.

Now, probably the most important part of this tutorial is to make sure you are wearing proper safety gear when going near the fry machine. That means at a bare minimum, you will need some gloves; but if you would feel better, get an apron and even some glasses to protect your eyes.

When you’re using the brush to clean your fry tank, be sure to clean in between the heating surfaces, including the tank tubes, the sides of the tank, and the cold zone. This will ensure you have a very clean fry tank when it’s put back into service.

Once you’ve completed the cleaning, you can open the fryer door and turn the thermostat off. Reset the temperature to 350 degrees F for the next person who may use the fryer. Wearing your safety gear, open the door of the tank, take the drain pipe, and screw it into the drain vacuum. Put some kind of container or bucket underneath it, and that is where all the boil-out or cleaning solution will be drained in to. You will need to continue to flush out the deep fryer with about 3 to 4 more buckets of water – so don’t take away your container or bucket just yet!

Put on your gloves once again (if you took them off at any point at the aforementioned step), and take a towel to wipe down the surfaces of the deep fryer. This will dry them down. If you can, leave the drain valve open overnight to let the fryer air dry completely. When you come back to it, you should have a super-clean deep fryer that is ready for the next day’s cooking!
