The most important supplies are protective gear.
You'll need nitrile gloves. These kinds of gloves will protect your delicate skin. Also, wear a pair of safety glasses to prevent hot oil from splashing into your eyes.
Oil causes grease stains on clothes and can burn your skin. Wear a heavy vinyl apron to protect your clothing and skin.

If you can, also buy a fryer coil brush. This small brush can get into spots that the other brush can't reach.
A fryer rod is a neat tool that helps you pick out leftover food bits out of the drain tube.
A drain valve extension is a metal tube that can thread onto the drain flow tube to empty the fryer oil. You'll also need a stock pot or use a stainless steel bowl or bucket to catch the used frying oil.
How to Clean a Fryer
Once you've gathered your supplies, it's time to start cleaning the deep fryer.
First of all, unplug the fryer and let the oil cool. Use a thermometer to make sure the oil is less than 150 degrees Fahrenheit.
Take out any baskets and move them to the sink.
Next, carefully drain the oil into the container it came in. Use a slotted ladle to scoop out any crumbs from the bottom of the fryer.
Once the oil is out, use a metal spatula to loosen the gunk on the sides of the fryer. Wet a paper towel and use it to wipe up the sides.
Now you can put the commercial fryer into the sink and fill it with hot water. Add a squirt of dish soap.
Use your scrubbing brushes to scrub the fryer. Pour out the soapy water and refill the fryer with clean water.
Add 1/2 cup of white vinegar to the fryer. Dip a clean rag into the fryer and wipe all the inside surfaces.
Rinse the fryer with hot, clean water one more time.
Dry all over the fryer with a lint-free cloth. Wipe the heating element with a damp rag. Then dry it.
Clean the Counter and Fryer Baskets
While you're cleaning a deep fryer, you'll also need to clean the frying baskets and the counter in front of the deep fryer.
Use a degreasing spray and liberally apply it to the counter. Let it soak in for at least 10 minutes while you work on the fryer baskets.
Fill the sink with hot water and a squirt of dish soap. Soak the frying baskets and scrub them with a wet rag.
Deep fryer cleaning is a task that should be on your restaurant kitchen cleaning checklist.
