Cleaning Supplies You Will Need

Before diving into the step-by-step cleaning process, gather the following supplies:

• Super absorbent paper towels or cleaning rags
• Mild dish soap
• Small spatula or spoon
• Long-handled scrub brush
• Pan scraper
• Soft bristle cleaning brush
• Baking soda
• Distilled white vinegar
• Stainless steel polish (for stainless steel fryer models)

You likely already have most, if not all, of these supplies in your kitchen.

Safety First – Preparing to Clean Your Fryer

As with most kitchen cleaning tasks, safety should be your first concern when cleaning your deep fryer:

• Unplug the deep fryer – This eliminates the risk of electric shock while cleaning.
• Allow oil to cool completely – Hot oil can severely burn skin. Allow several hours for the oil to return to room temperature before handling.
• Remove detachable parts – Many deep fryers have removable frying baskets and heating elements. Take these out before cleaning.
• Protect electric cords – Wrap all power cords in paper towels or plastic wrap to keep moisture away.
• Wear gloves – Rubber cleaning gloves guard hands from hot surfaces and cleaning chemicals.
• Don’t submerge heating element – The heating element should never be fully submerged in liquid, as this poses an electrocution risk.
• Ventilate the area – Clean your fryer in a well-ventilated space to minimize inhaling fumes. Open windows and run kitchen fans.

With safety steps addressed, you can confidently clean your fryer.

Step 1: Remove Excess Fryer Oil

Before scrubbing down the interior, eliminate leftover frying oil:

• If oil is still warm, allow it to fully cool first.
• Use super absorbent paper towels to soak up room temperature oil.
• Carefully transfer saturated towels to a metal container for proper disposal.
• For small amounts of difficult-to-reach oil, use a spoon or spatula.
• Removing old oil will prevent it from turning rancid over time.

With excess oil eliminated, cleaning solutions can now reach all surfaces.

Step 2: Clean the Fryer’s Exterior

Tackle the external components first:

• Wipe down the lid, outside walls, control panels, etc. using a soft damp cloth, warm water, and a small amount of dish soap.
• Carefully scrub to loosen any baked-on oil or food residue.
• Pay special attention to vents, corners, and crevices where grease accumulates.
• Use a small brush to detail hard-to-reach areas if needed.
• Rinse surfaces clean and dry thoroughly with a lint-free towel.
• Avoid using abrasive scrubbers or cleaners which could scratch exterior surfaces.

Thorough external cleaning prevents messes, maintains appearance, and removes flammable grease buildup.

Step 3: Wash Out Fryer’s Food Basket

The removable fryer basket houses food as its cooked, meaning it likely contains the most debris.

To clean:

• If possible, let the basket soak for 10-20 minutes in hot, soapy water to loosen stuck-on residue before scrubbing.
• Use a spatula, brush, or pan scraper to dislodge any loose particles.
• Apply more hot, soapy water and scrub with a nylon brush inside and out.
• If needed, make a paste with baking soda to break down stubborn oil stains.
• Rinse very thoroughly until all soap residue is eliminated.
• Allow the basket to air dry completely before replacing in the fryer.

A pristine frying basket maximizes heat transfer efficiency for quicker cooking.

Step 4: Deep Clean Fryer’s Interior

Now for the most crucial step – meticulously cleaning the inside metal walls and bottom of the fryer vat.

Here is a safe, effective process:

• Remove all removable parts – baskets, heating elements, crumb trays, etc.
• Drain all old cooking oil from the fryer vat.
• Fill the vat about 2/3 full with hot water and a small amount of dish detergent.
• Use long handled brushes to scrub all interior surfaces, forcing water into every nook and cranny.
• Drain the soapy water and thoroughly rinse away all suds with clean water.
• Refill the vat with hot water and stir in 1-2 tablespoons of distilled white vinegar.
• Allow vinegar solution to soak for 5-10 minutes to further dissolve grease.
• Scrub again with brushes. Then drain and rinse once more with hot water.
• Use paper towels or clean soft cloths to carefully dry the vat interior.

Vinegar neutralizes stubborn oil residue without harsh fumes or safety risks of other cleaning solutions.

Step 5: Descale Fryer Heating Elements

Scale buildup on heating elements reduces efficiency and can be a fire hazard if unchecked.

To remove scale deposits:

• Create a paste of 2 parts baking soda to 1 part water.
• Dip a soft bristle brush into the paste.
• Gently brush paste onto visible scale areas of the heating element. * Let it sit for a few minutes to dissolve mineral buildup.
• Scrub gently with brush then rinse clean.
• Repeat as needed for stubborn areas until all scale is removed.
• Wipe heating elements dry with paper towels once descaled.

Step 6: Polish Stainless Steel Components

Stainless steel deep fryer models require a bit of extra care. Prevent corrosion and maintain their sleek, reflective properties by:

• Using stainless steel polish or cleaner and a microfiber cloth, rub gently with the grain over all exterior stainless surfaces.
• Buff off any streaks for a bright uniform shine.
• Remove stubborn spots using a paste of baking soda and water. Lightly scrub then rinse.
• Avoid cleaning stainless steel parts with abrasive pads, steel wool, or chlorine-based cleaners which degrade their protective finish.

Step 7: Rinse and Dry Completely

With all cleaning steps finished:

• Thoroughly rinse away any lingering cleaning product residue inside the vat, heating elements, baskets and other detachable pieces.
• Wipe down all surfaces with clean lint-free towels to eliminate standing moisture.
• Allow all components to air dry fully before reassembling or refilling oil.

This prevents moisture-induced issues like corrosion, electrical shorts or oil contamination later on.

Maintenance Tips for Your Deep Fryer

Beyond periodic deep cleaning, maintaining a few daily and weekly care habits will keep your fryer operating in top form:

Daily Fryer Care

• Skim off and dispose of any loose food particles floating in oil between batches
• Use fryer filtration systems to prolong oil life
• Ensure oil is drained fully from baskets/strainers before stacking wet food inside
• Wipe up any minor spills or drips on exterior surfaces

Weekly Fryer Care

• Give fryer interior a quick wipe down with paper towels
• Check ventilation filters and hoods; clean if needed
• Deep clean all components at least once per week under heavy use

When Changing Frying Oil

• Allow oil to fully cool before handling
• Carefully pour old oil into appropriate containers for disposal
• Never pour oil down drains or allow it to sit out attracting pests
• Replace with fresh oil based on particular fryer model guidelines

Storing Your Fryer

• Ensure fryer is fully dried if storing for prolonged periods
• Wrap and secure any detachable cords neatly

Using Fryer Filtration Systems

Deep frying oil breaks down over time from heat, air, moisture and food particles. This degrades oil quality and accelerates rancidity.

Fryer filtration systems are hugely beneficial accessories that extend usable oil life dramatically. They work by:

• Removing solid food particles suspended in oil to slow contamination
• Eliminating free fatty acids that make oil go rancid faster
• Filtering oxidation particles that result from heat/air degradation

High quality fryer filters can strain your oil many times over for weeks or months of use before needing replacement. This saves money while ensuring clean, fresh tasting food.

Filtration types include:

Manually Operated Filters

• Inexpensive and simple gravity filtration units
• Require manually pumping oil through filter pads
• Ideal for home deep fryers or very light commercial use

Self-Contained Automatic Filters

• Contain all filtration components internally
• Automatically pump and filter oil with the press of a button
• Don’t take up additional space next to the fryer
• Best suited for commercial kitchens

Separate Automatic Filtration Systems

• external floor standing filtration system
• Hooks to fryer piping to continually filter large quantities of oil
• Includes oil storage tank, industrial pump and filters
• Designed for high volume commercial deep frying needs

When to Change Your Fryer Oil

With or without filtration, frying oil has a limited lifespan and needs changing periodically. But when?

For Unfiltered Fryers

• Change oil every 1 week (home use)
• Change oil every 2-3 days (commercial kitchens)

For Filtered Fryers

• Change oil every 1-2 months (home use)
• Change oil every 2-3 weeks (commercial kitchens)

Additional Replace Oil if:

• Dark, cloudy appearance develops
• Oil smokes or foams excessively during frying
• Foods soak up more oil or start sticking
• Foods absorb or impart unpleasant flavors

Discard oil immediately if:

• You smell rancid odors
• Bubbles appear indicating moisture contamination
• Carbon particles form indicating heat damage

Fryer Safety Tips

Beyond cleaning, employing safe frying practices prevents accidents:

• Position fryers away from water sources and flammable materials
• Avoid overfilling fryer vat – oil expands significantly when hot
• Ensure fryer is on a stable surface, securely plugged in
• Don’t overcrowd fryer baskets – leads to uneven cooking
• Wear oil resistant gloves, aprons, closed toe shoes
• Exercise extreme caution handling hot oil. Avoid water splatter.
• Unplug unit when not in use and overnight.

When to Replace Your Deep Fryer

With regular cleaning and maintenance, quality fryers can operate reliably for 6-8 years (home models) or 3-5 years (commercial models).

Consider purchasing a new fryer if:

• Fryer is over 8 years old (home) or 5 years old (commercial)
• Structural damage develops like big dents or cracks
