How to Clean and Maintain Your Moffat Griddle
What a Moffat griddle is and why it matters for your kitchen
A Moffat griddle is a commercial-grade cooking surface made by Moffat, a manufacturer known for restaurant and institutional kitchen equipment. If you own one, you likely use it for high-volume cooking — pancakes, grilled cheese, burgers, or breakfast service. The flat steel cooking surface heats evenly and holds temperature well, which is why it's standard in diners and catering kitchens.
Unlike a home stovetop griddle, a Moffat griddle is a standalone piece of equipment with its own heating system underneath. It sits on a stand or counter and connects to gas or electricity depending on the model. Because it's built for professional use, it can handle constant cooking and heavy scraping — but it also needs regular maintenance to stay safe and perform well.
If you're storing food near or around your griddle, or if you're using it in a kitchen where you also keep a refrigerator, understanding how to keep the griddle clean and maintained protects both your food safety and your equipment investment.
Key Takeaways
- Moffat griddles must be cleaned daily after use while the surface is still warm, using a metal scraper and damp cloth to remove food residue and prevent rust.
- The griddle surface should be seasoned with a thin coat of oil after cleaning to maintain the non-stick properties and prevent corrosion.
- Check the gas connection, electrical cord, and thermostat regularly for damage or loose fittings, and have a professional service the unit annually.
- Store cleaning tools and supplies away from the griddle itself, and keep the area around the griddle clear to prevent cross-contamination with refrigerated foods.
- If your griddle sits in a kitchen with a refrigerator, maintain at least two feet of clearance to allow air circulation and prevent heat damage to nearby appliances.
Daily cleaning routine for the cooking surface
Clean your Moffat griddle immediately after use, while the surface is still warm but cool enough to touch safely. A warm surface is easier to clean because food residue hasn't hardened, and the metal is still pliable enough to respond to scraping without cracking.
Use a metal griddle scraper — the kind with a flat blade designed for this purpose — to push all food debris toward the edge and into the grease trap or collection area. Push in one direction rather than scrubbing back and forth; this prevents scratching the surface unevenly. Once you've removed the bulk of the food, wipe the surface with a damp cloth or paper towel to lift any remaining particles.
After wiping, apply a very thin coat of griddle oil or mineral oil to the entire cooking surface while it's still slightly warm. This step is critical: the oil seals the steel and prevents rust and oxidation. Use just enough oil to create a light sheen — too much oil will smoke and burn the next time you cook. Let the griddle cool completely before you leave it.
Weekly deep cleaning and inspection
Once a week, perform a more thorough cleaning to remove buildup that daily wiping may have missed. Let the griddle cool completely, then use a griddle cleaning stone (a porous block made for this purpose) or a soft-bristled brush with warm soapy water to gently scrub the entire surface in circular motions. This removes stuck-on grease and carbon without damaging the seasoning.
Rinse thoroughly with clean water and dry immediately with a cloth. Any water left on the surface will cause rust. Once dry, apply your protective oil coat again and let it sit overnight.
While you're doing this cleaning, inspect the surface for cracks, warping, or areas where the metal looks discolored or pitted. Small surface rust can be treated with a griddle restoration product, but deep pitting or cracks mean the griddle needs professional repair or replacement.
Checking the heating system and connections
The griddle's heating system — whether gas or electric — needs regular inspection to stay safe and efficient. For gas griddles, check the connection where the gas line meets the griddle at least monthly. Look for any visible cracks in the line, and listen for a hissing sound that would indicate a leak. If you smell gas, turn off the griddle immediately, open windows, and call a service technician. Never attempt to repair a gas connection yourself.
For electric griddles, inspect the power cord for fraying, cracks, or exposed wires. Make sure the cord isn't pinched under the griddle or wrapped tightly around it, which can damage the insulation. Check that the plug fits snugly into the outlet and that the outlet itself isn't loose or damaged.
Both types should have a thermostat or temperature control dial. Test it monthly by setting it to a known temperature and using an infrared thermometer to verify the surface actually reaches that heat. If the griddle won't heat to the set temperature, or if it overheats, the thermostat may need calibration or replacement by a professional.
Seasonal maintenance and professional service
Schedule a professional service visit at least once a year, ideally before your busiest cooking season. A technician will check the thermostat calibration, inspect the burner or heating element, test all connections, and clean internal components that you can't reach. They'll also check for any wear that might affect safety or performance.
If your griddle is used very heavily — daily in a commercial kitchen, for instance — you may need service twice a year. Keep records of all service visits and any repairs, because this documentation helps you spot patterns and plan for replacement if the griddle is aging.
Before winter or during long periods when the griddle won't be used, clean it thoroughly, apply a protective oil coat, and cover it with a fitted cover to keep dust and moisture away. Store it in a dry location if possible. If it must stay in a damp kitchen, run it briefly once a month to warm the surface and evaporate any moisture that may have accumulated.
Positioning your griddle safely near refrigeration
If your griddle is in the same kitchen as a refrigerator, maintain at least two feet of clearance between them. The griddle generates significant heat, and that heat can force your refrigerator to work harder and shorten its lifespan. Poor air circulation around the fridge also creates warm spots inside where food can spoil faster.
Keep cleaning supplies, oils, and any flammable materials away from the griddle itself. Store them in a cabinet or on a shelf at least three feet away. This prevents accidental spills onto the hot surface and reduces the risk of fire.
Never store raw or cooked food directly on or immediately next to the griddle. The heat and steam can affect food safety and quality. Use a separate prep table or counter, and keep that area clean and separate from the griddle's work zone. If grease splatters from the griddle onto nearby surfaces, wipe them down immediately to prevent cross-contamination and to keep the kitchen sanitary.
Troubleshooting common griddle problems
If your griddle surface is sticking or food is burning unevenly, the seasoning layer may be worn away or uneven. Clean the surface thoroughly, dry it completely, and apply a fresh, thin coat of griddle oil. Let it cure for several hours before cooking again. If sticking persists, the surface may have developed pitting or warping that requires professional repair.
If the griddle heats unevenly — hot spots in one area and cool spots in another — the thermostat may be failing, or the heating element may have internal damage. This is a job for a professional technician. Do not attempt to adjust or repair the heating system yourself, as this can create a fire or electrical hazard.
Rust spots that appear despite regular oiling usually mean the surface wasn't dried completely after cleaning, or the oil coat was too thin. Treat small rust spots with a griddle restoration product or fine steel wool, then re-season. If rust returns quickly, the griddle may have a crack that's allowing moisture to seep in, and you'll need professional assessment.
Frequently Asked Questions
Can I use soap and water to clean my Moffat griddle?
Yes, warm soapy water is fine for weekly deep cleaning, but always dry the surface completely afterward and apply a protective oil coat. Never leave water sitting on the griddle, as this causes rust. For daily cleaning after cooking, a damp cloth and scraper are usually enough without soap.
What type of oil should I use to season the griddle?
Griddle oil, mineral oil, or vegetable oil all work. Avoid olive oil or other oils with low smoke points, as they'll burn and create smoke. Use the thinnest coat possible — just enough to create a light sheen. The goal is protection, not cooking oil.
How do I know if my griddle needs professional repair?
Call a technician if you notice cracks in the cooking surface, uneven heating that doesn't improve with re-seasoning, a gas smell, visible damage to the power cord, or if the griddle won't reach the temperature you set. Don't wait — these issues can affect safety and food quality.
Is it normal for my griddle to smoke when I first turn it on?
Light smoke from the oil seasoning is normal, especially if you applied oil recently. However, heavy smoke or a burning smell means either too much oil was applied or there's debris on the surface. Turn off the griddle, let it cool, wipe it clean, and reapply a thinner oil coat.
How far should my griddle be from a refrigerator?
Keep at least two feet of clearance to allow air to circulate around the refrigerator. This prevents the fridge from overheating and keeps it running efficiently. If your kitchen is small, position the griddle so heat vents away from the fridge, and make sure the fridge's condenser coils aren't blocked.
