A commercial griddle is the workhorse of a busy kitchen. It handles breakfast rushes, smash burgers, grilled sandwiches, fajitas and a hundred other menu items every single day. But that hard work leaves behind grease, carbonized food and sticky residue, and if you ignore it, the surface will punish you with uneven heating, off flavors, smoke and expensive repairs.

The good news is that keeping a griddle in great shape is not complicated. It just needs the right tools, the right order of steps and a consistent routine. In this guide, based on the topic of the video "Imperial Griddle Cleaning" from Imperial Commercial Cooking Equipment, we walk through the whole process so your griddle stays safe, efficient and ready to cook.

Note: always follow the cleaning instructions in your own griddle's manual, because materials and finishes differ between models.

Why Griddle Cleaning Matters

Many kitchens treat cleaning as an end-of-night chore. In reality, it is one of the most important parts of equipment care. Here is why.

Food quality. Burnt bits and old grease transfer bitter flavors to fresh food. A pancake that tastes like last night's onions is a quick way to lose a customer.

Even cooking. A thick layer of carbon acts like insulation. It creates cold and hot spots, so some food overcooks while other food stays raw in the middle.

Safety. Built-up grease is fuel. It increases the risk of flare-ups and kitchen fires, and a greasy trough or drawer is a hazard you do not want near an open flame or hot element.

Equipment life. Residue left to harden can pit and damage the cooking surface, clog grease channels and shorten the life of the whole unit. Regular cleaning is much cheaper than replacement.

Health inspections. Inspectors look at cooking surfaces and grease handling. A clean griddle is an easy win.

What You Need Before You Start

Gather your supplies first so you are not hunting for tools while the griddle cools down.

• A sturdy griddle scraper with a sharp, intact blade
• Griddle bricks, screens or pads designed for commercial use
• A high-heat, non-abrasive cleaning solution or griddle cleaner approved for your surface
• Heat-resistant gloves and long sleeves
• Clean cloths or towels and a squeegee-style tool if you have one
• A grease-safe container for scrapings and drained oil
• Cooking oil for re-seasoning after cleaning
• A bucket of warm water for wiping down the non-cooking areas

Safety gear is not optional. A hot griddle can still cause serious burns even when it feels "off," so protect your hands and forearms.

Step 1: Scrape Off Loose Food and Grease While the Surface Is Warm

The easiest time to clean a griddle is right after service while it is still warm, not stone cold and not blazing hot. At a moderate temperature, grease is liquid and food residue is loose.

Use your scraper at a low angle and push debris toward the grease trough or channel. Work in long, firm strokes from the back to the front, and keep the blade flat so you do not gouge the surface. Do this in sections rather than trying to clear the entire plate in one pass.

Never use your hands or a wet cloth on a very hot plate. If you need to remove stuck-on pieces, use the scraper, not your fingers.

Step 2: Empty the Grease Trough and Drawer

Once the main debris is scraped forward, clear the trough. Empty the grease collection container carefully into an approved waste container. Do not pour hot grease down the drain, because it will solidify and clog your plumbing.

Wipe the trough with a paper towel or cloth to remove any remaining oil. If your griddle has a removable drip tray or drawer, take it out and wash it with hot water and degreaser at the end of each day.

Step 3: Apply Cleaner and Scrub

With the loose material gone, it is time to treat the baked-on residue. Follow the product directions for your cleaner, then use a griddle brick or screen to scrub the surface. Move with the grain of the metal and apply steady, even pressure.

A few tips for this stage:

• Use a griddle screen for daily cleaning because it is gentler and still effective.
• Reserve a grill brick for heavier buildup, as it is more abrasive.
• Wear gloves and keep your arm clear of the hot surface.
• Avoid harsh chemicals that are not rated for food-contact cooking surfaces.
• Do not use steel wool or metal brushes unless the manufacturer says it is safe. They can scratch and leave metal fragments behind.

Scrub until the surface looks uniform and the residue lifts away. You will see the difference immediately as the plate returns to a smooth, even tone.

Step 4: Rinse or Wipe Away the Cleaner Properly

Residual cleaner is one of the most common mistakes. It can leave a film on the griddle that flavors the next day's food. After scrubbing, remove all slurry and cleaner with clean damp cloths or the method your manufacturer recommends, then wipe the surface dry.

Be careful with water on a hot plate. Cold water on very hot steel can cause steam burns and, in some cases, warping. Let the surface cool to a safe level first, or use only the amount of water your model instructions allow.

Step 5: Dry Completely

A wet griddle is a rusting griddle, especially if you have a carbon steel or plain steel plate. Make sure the surface is completely dry. You can use a lint-free towel, then briefly warm the plate on low heat to drive off any remaining moisture.

Step 6: Re-Season the Surface

Seasoning is what protects your griddle and gives it a naturally non-stick quality. After cleaning, apply a very thin coat of high-smoke-point cooking oil across the whole plate, including the edges. Heat the griddle gently until the oil begins to smoke lightly, then wipe off any excess with a clean cloth.

Do not use too much oil. A thick coating turns sticky and gummy rather than forming a hard protective layer. Think thin and even.

This step is especially important for steel plates. Chrome-plated and some other finishes have different care needs, so check your guide.

Step 7: Wipe Down the Exterior and Surrounding Areas

A clean cooking surface sitting inside a greasy cabinet is only half a job. Wipe down the front panel, knobs, backsplash, side walls and the equipment stand with warm water and a mild degreaser. Pay attention to the knobs and handles, which collect a lot of fingerprints and grease and are touched constantly.

Avoid spraying water directly into controls, gas valves or electrical components.

Daily, Weekly and Monthly Cleaning Schedule

Good griddle care works best when it is a habit. Here is a simple schedule you can adapt.

After every shift (daily):

• Scrape the surface and clear the grease trough
• Empty and wipe the drip tray
• Scrub with a screen or brick and cleaner as needed
• Wipe, dry and apply a thin protective oil layer

Weekly:

• Wash the grease drawer and splash guards thoroughly
• Deep-clean around the edges and corners
• Wipe down all exterior stainless surfaces
• Check the scraper blade and replace worn tools

Monthly:

• Do a deeper descaling or heavy-duty clean following manufacturer guidance
• Inspect for warping, pitting or damage to the plate
• Check gas connections, burners or heating elements and have a technician service anything that looks wrong
• Review your cleaning supplies and restock

Common Griddle Cleaning Mistakes to Avoid

Even experienced cooks slip up. Watch out for these common errors.

1. Waiting too long. The longer residue sits, the harder it bonds to the plate. Clean every day.
2. Using the wrong tools. Abrasive pads and metal brushes can scratch the surface and ruin the finish.
3. Shocking a hot plate with cold water. This can cause warping and dangerous steam.
4. Skipping the seasoning step. Without a protective layer, food sticks and the plate can rust.
5. Over-oiling. Too much oil leads to sticky residue and smoke.
6. Ignoring the trough. A full, neglected trough is a fire and hygiene risk.
7. Forgetting safety gear. Burns are one of the most common kitchen injuries, and they are preventable.
8. Using unapproved chemicals. Always choose products rated for food-contact cooking equipment.

Signs Your Griddle Needs Extra Attention

Even with good daily habits, some problems call for a deeper clean or professional help. Watch for these warning signs:

• Food sticking even after seasoning
• Visible rust, pitting or discoloration that will not scrub away
• Warped or uneven surface
• Hot and cold spots when preheated
• Persistent smoke when the griddle is on
• Unusual smells or burnt odors that remain after cleaning

If you notice any of these, stop and investigate. It may be time to restore the surface or call a qualified service technician.

Tips to Make Griddle Cleaning Faster and Easier

• Clean as you cook. Scrape the surface between orders during slow moments so debris never builds up.
• Keep your tools in one place. A dedicated cleaning station saves minutes every night.
• Train every team member. Make sure everyone follows the same steps so the quality of care does not depend on who closes.
• Use a checklist. A laminated closing checklist helps nothing get missed.
• Replace worn scraper blades. A dull blade makes you work harder and can damage the plate.
• Let the equipment cool at the right pace. Do not rush by dumping water on a blazing plate.

Final Thoughts

A clean griddle is not just about appearances. It protects your food quality, your staff, your equipment and your reputation. The routine is simple: scrape while warm, clear the grease, scrub with the right tools, remove all cleaner, dry thoroughly and re-season with a thin layer of oil. Do that every day, add a deeper weekly and monthly clean, and your griddle will reward you with years of reliable, even performance.
