Blog 3 - How to clean commercial deep fryers

The task of cleaning a deep fryer is essential for any kitchen. It doesn’t matter where it is – in a café, restaurant or fast-food chain – if there’s an industrial deep-fryer around then it needs to be cleaned on a regular basis!

There are places that have lots fried foods on their menu but never clean out their fryers. There are some restaurants and chains who do this once every month at most while others get them clean every day after closing time.

Using dirty oil in an unclean fryer can increase cooking times, worsen taste & aroma of dishes while increasing energy consumption. However, life becomes easier when you make use of modern technologies which make cleaning easy and safe by using filtration fryers or portable filtration systems.


During cleaning, you will work with the remnants of hot oil and its drops can cause burns to you. Therefore, wear a protective apron, safety goggles or a mask and thick gloves.


Appropriate filter paper. It’s really that simple!


Step 1. Prepare the filter assembly

Place a sheet of filter paper on the bottom of the filter pan and fix the paper with a paper retainer. Attach the filter pan hose to the inlet port of the quick-disconnect knob. Install a frame for catching crumbs and a basket. Make sure that the front and rear handles of the support rod are fixed.

Step 2. Turn the fryer off

This is a given, however after a long working day forgetting the basics happens all too often. Make sure that the unit is turned off.

Step 3. Use the drain valve extension

Put the drain valve extension to the drain, make sure the opening is pointed downwards.

Step 4. Start the filtration

Place the filter unit under the drain valve, slowly open it. While the oil is filling the filter pan, make sure that the large crumbs are caught by the crumb catching frame.

When all the oil is in the filter pan, place the return hose to the fryer, and only then turn on the filter pump. Do it by turning the toggle switch on the front of the machine up.

The oil from the filter pan will be fed back into the fryer through the filter paper and flow back down through the drain. Use the recirculating oil to clean the walls of the fryer for about 5 minutes. Then turn off the filter pump by moving the toggle switch position down. Allow the oil to drain into the filter pan.

Then use paper towels to wipe the dirty surfaces inside the fryer. Do not use water and detergents, they can spoil the pump and motor of the filtration system.

Step 5. Re-fill the deep fryer with oil

Close the fryer drain valve so that the oil cannot spill out again.

Place the return hose into the fryer and turn on the filter pump again. Fill the fryer with oil until all the oil from the filter pan flows back into the fryer.

One filter pad should be enough to clean two fryers. Using the supplied scoop, you need to carefully clean the filter paper after the first filtration. If the pad is torn, then it needs to be replaced.

Step 6. Clean it up

Remove the used filter paper.

All parts of the filtration system can be washed normally, except for the filter pan. Therefore, simply wipe it with paper towels.
