Cleaning and boiling out the deep fryer are required to remove the fat buildup in the deep fryer’s baskets and equipment.

Proper maintenance of the fryer oil should be complete every week, or at least once a month. However, restaurants that operate often may need to boil their high-use fryers more constantly, potentially weekly.

 Cleaning Technique

  • While cleaning, our professionals will remove all food, grease, and oil splatters and spills on the floor and around cooking equipment before commencing.
  • We will then shut off the fryer, seal the gas supply intake, and extinguish the pilot light (if gas).
  • Unplugged from the wall, the oil within the power supply must cool down before plugging back in. Usually, fryers are kept at a constant temperature of approximately 350 degrees.
  • Fahrenheit, so it will take a very extended time to properly cool.
  • The technician empties the oil from the fryer into a spill-resistant steel container whenever the temperature reaches less than 150 degrees Fahrenheit.
  • Finally, we scrape out any remaining crumbs and food particles from the bottom of the fryer, then use a scraper to remove grease and oil accumulation from the inside of the walls, corners, and base. The fresh oil will have an undesirable flavor if the scrape is not done correctly.
  • To get oil out of the drainpipe, our expert will use a fryer washing rod. Unused grease in the fryer will result in mechanical and safety concerns.
  • Once the fryer is full of water and degreasing resolution, we then proceed to the level line. Since the cleaning solution will clear off any caked-on fat, the technician generally leaves the fryer baskets and tools inside the deep fryer throughout boil-outs.
  • Once the cleaning solution has been boiling for 20 to 30 minutes, the heater is switched back on to boil the water and thoroughly clean the machine. You may have to clean the fryer if it is filthy.
  • It restarts when the specified time has passed. To enable the water and solution to cool before disposing, the solution is allowed to cool fully before disposal.
  • Once the temperature has been lowered, our experts will set aside the trays and utensils for further cleaning. 
  • We soak baskets in hot water and clean liquid if grease and oil are still present on their inside and exterior, as well as on kitchenware. 
  • To do a thorough job using a soft bristle brush, we begin by cleaning the base, internal walls, and outside the fryer’s basket.
  •  We will focus on the areas where food and oil collect. When this step is completed, the technician will do it again (if necessary).
  • The next step is to remove the containers and utensils from the mop, giving them enough time to dry fully. They should never place wet objects in the oil.
  • The technician will clean off the inner of the fryer and will then clean oil, grease, and food particles from locations where they are still present.
  • The technician will first wet-wash the inside with a rinsing agent, after which they will use water to rinse the interior to clear away any cleaning mixture or leftover residue. 
  • When leftovers remain, there will be a strange flavor, and the next batch of oil will be compromised.
  • Then, we use a degreasing solution to wash the external of the deep fryer and the counter, so it may sit for a few minutes to wash away the oil. 
  • The non-abrasive cloth and degreasing cleaning solution are used to clean the area and remove the existing dirt.
  • Once the whole fryer has been cleaned, the heating element is thoroughly dried and then wiped down.

We’ll conclude by cleaning and wiping down the equipment and flooring. An insubstantial coating of oil forms on the counter directly in front of the fryer, making it more challenging to maneuver in regular commercial kitchen settings. To decrease the chances of slips and falls, our personnel will carefully clean the area surrounding the equipment.
