How to Clean a Deep Fryer

We covered the tools you are going to need, so now take a look at this step-by-step guide for properly cleaning the dryer.

Step 1: 

Turn off the fryer in order for it to cool down so you don’t get burned from hot oil. After it’s cooled, use the special metal tube to drain the oil from the fryer into the container or bowl that you prepared beforehand.

Step 2:

Use a scraper to scrape as much build-up from the sides as possible, and then dispose of the removed leftovers.

Step 3:

Fill the fryer with water in the exact amount as you would with oil. Add detergent to the water and then stir to mix it.

Step 4:

Turn on the fryer and wait for the water and dish detergent to boil. This will remove all the leftover stains on the sides. Next, turn off the fryer, remove the water and wipe the inside. Rinse the dryer with clean water.

Step 5 (extra):

Check that all the parts of the fryer are dry before using it or storing it.

How to Clean a Deep Fryer: Additional ideas 

  • If dish detergent doesn’t remove the stains, you can use oven cleaners. Keep in mind that these are strong chemicals, so use them carefully and do an extra rinse or two when you are done to be sure that nothing toxic remains in the fryer.
  • Another thing you can use for stubborn stains is WD-40. Again, use with caution and wash the dryer a couple of times with clean water.
  • Use vinegar combined with hot water and apply to the affected surfaces. Rinse.
  • Mix baking soda with water to make a paste, then rub it on the inside of the fryer. Remove the paste with a sponge and clean the fryer with water.

If you don’t want to waste your time cleaning the fryer, there are professional cleaners that offer these services. You can research which are available in your area.

How often are you supposed to clean a deep fryer?

The more you use your fryer, the more you will need to clean it. If you use your deep fryer from time to time, follow the steps mentioned above to properly clean it.

If you fry food every day, it’s really time-consuming to thoroughly clean the fryer.  You can reuse the oil a couple of times and clean it at the end of each week using the guide I’ve provided.

If you use the fryer for your restaurant or a similar business, it’s important to clean it daily to ensure quality food for your customers. 

How to Clean a Deep Fryer: Deep frying at home – tips and tricks

  • Always be close to your fryer when using it. Mind the temperature of the oil.
  • If you can, have a fire extinguisher nearby at all times.
  • Do not put too much food at once in order to fry it better.
  • Keep track of how many times the same oil is used and change it accordingly.
  • Soak water from the food with a paper towel before putting it in the fryer to avoid a reaction with the hot oil.
  • To keep your fryer working longer, avoid seasoning the food with salt when it’s already in the fryer. Hot oil and salt create a reaction that causes additional damages to the fryer.
  • Before using any of the previously mentioned methods, read the user manual for your specific fryer. Some fryers need special treatment.
