How to Clean a Commercial Deep Fryer

Clean your commercial deep fryers the tried and true way!

A commercial kitchen simply wouldn’t be complete without the trusty deep fryer. It’s the workhorse that churns out delicious fries, crispy tenders, golden onion rings, and just about anything else your cooking staff can imagine—all at a moment’s notice!

But, with daily use comes the need for regular maintenance. Proper cleaning is essential not only for preserving the flavor of your food but also for prolonging the life of your fryer. In this guide, we’ll walk you through the tried-‘n’-true “boil-out” cleaning method, a highly effective approach to keeping your commercial deep fryer in tip-top shape.

Read along as we walk you through the most effective way to clean a commercial deep fryer.

Step 1: Prioritize Safety

Before you begin, make sure to turn off the power to your deep fryer. This can be done by closing the gas supply inlet or unplugging the power source. Allow the oil to cool down to a safe temperature, ideally below 150 degrees Fahrenheit.

Step 2: Draining and Disassembling

Once the oil has cooled, carefully drain it into a suitable container for proper disposal or recycling. Remove any baskets or holders from the fryer. Take a cleaning rod or scraper and diligently scrub away any built-up residue from the interior walls, corners, and base. Ensure that you brush, wipe, and rinse away any debris.

Step 3: Mixing the Cleaning Solution

Fill the deep fryer tank up to the indicated level line with cool, clean water. Add an appropriate cleaning solution to the water. This specialized detergent (as indicated for your particular deep fryer; consult the manual or manufacturer) will help loosen tough grease and oil stains, making the cleaning process all the more effective.

Step 4: Boiling the Solution

Turn the deep fryer back on and allow the water and cleaning solution to come to a boil. Let them boil for at least 10 minutes. If there’s excessive accumulation, it’s best to extend the boiling time to 15-20 minutes. This step ensures that the cleaning solution thoroughly dissolves and removes stubborn grease and oil.

Step 5: Final Cleaning and Rinse

After the appropriate boiling time, turn off the fryer and allow the water and cleaning solution to cool completely. Slowly drain the solution from the fryer and use a brush to clean the sides and heating elements, ensuring all residue is removed. Rinse the fryer thoroughly with hot water to eliminate any traces of cleaning chemicals or leftover residue. Allow the basin, baskets, and frying utensils to air dry completely before adding fresh oil for future use.

Closing Thoughts

Following these simple steps will help you to clean your commercial deep fryer with no trouble. Remember: regular cleaning not only extends the life of your equipment but also ensures the quality of your culinary creations. Always prioritize safety throughout the process, and enjoy the benefits of a well-maintained fryer that consistently delivers mouthwatering dishes to satisfy your customers’ cravings!
