Regular cleaning of fryers is essential for many establishments such as bars, fast food restaurants and all those who rely heavily on their fryer. One of the best ways to clean your fryer is by boiling it.

In this post, we will provide you with a simple yet effective guide on how to clean your commercial deep fryer. We want to explain what it means to boil a fryer, why you should do it regularly, and how to successfully boil your fryer in a few simple steps. Remember that these are simple guidelines and tips. You should always refer to the fryer manufacturer’s guidelines before you begin cleaning your fryer.

Boil out a commercial fryer.

Boiling a fryer is the process of removing old oil, adding water and a cleaning solution, and then boiling the water to thoroughly clean the inside of the fryer and remove any stuck-on grime.

One of the main reasons why you should boil your deep fryer is because it maintains the correct flavor of your food. Dirt in your fryer can affect the oil and how your food is fried, which in turn affects its flavor.

If fryers aren’t cleaned regularly, you not only risk compromising the quality of the oil but also the taste of your food.

Boiling the fryer also helps the oil last longer. If you don’t bring your fryer to a boil, there can be proteins, polar contaminants, and other materials that can affect your oil immediately after you add it, causing it to deteriorate faster. By boiling your fryer, you ensure your oil lasts longer, so you can save money on replacement costs.

Also, if you get in the habit of regularly boiling your deep fryer, you will be able to use fewer chemicals, as you will prevent dirt from building up.

Keeping fryers clean also has the added benefit of keeping energy costs down. This is because charring on fryer walls and coils makes it difficult to heat fryers. Keeping them clean with regular fryer cleaning will save you time, energy, and a significant amount of money.

Before you begin the actual cleanup, it’s critical that you’re properly prepared with the right equipment. Cleaning a deep fryer is simple, but you’ll need a few tools for the job. This is what you will need:

  • Fryer cleaner
  • Heat resistant gloves
  • Protective glasses
  • Protective apron
  • Scrub brush
  • Frying rod
  • Stainless steel bucket
  • Lint-free cloths


Instructions for deep cleaning your fryer.

  • Turn off your commercial deep fryer and let it cool down to at least 60°C. Also remove the baskets and clean them separately. You can use our decarboniser machines to remove all the dirt embedded in the baskets effectively and easily.
  • Now that the oil is cold, drain it from the fryer into a suitable container ready for recycling or disposal. Also remove any leftover food that may be in the fryer, taking care that the drain is never blocked.
  • Clean the walls and bottom of the fryer with the scrub brush, using the fryer wand to clean hard-to-reach areas. Rinse the fryer with hot water to remove excess undrained fat.
  • Fill the fryer with cold water up to the level line. Next, add your fryer cleaner. Check the directions on the bottle to find the specific amount you need to use.
  • Turn the fryer back on and slowly bring the water and cleaning solution to a boil for 20 minutes. Never leave your deep fryer unattended at this stage as it may splash water.
  • Turn off the fryer and let the water cool completely. Once cooled, drain the water into the stainless steel bucket and dispose of properly.
  • When the water has drained, clean the inside of the fryer again and wipe it down with a lint free cloth to ensure all oil, food and other debris is removed. Again, use the fryer rod to get into all those nooks and crannies.
  • Rinse the fryer thoroughly with water to remove all cleaning solution. Use clean, lint-free cloths to dry all internal parts of the fryer.
  • Refill your fryer with fresh or recycled oil. Remember that using the oil filter the frequency of oil changes decreases, becoming between 50 and 60% less.


Cleaning your fryer at regular intervals can help improve the flavor quality of your fried foods, reduce oil replacement costs, and improve the life of your fryer.
