Why Clean a Grill Regularly?
It goes without saying that cleaning your commercial grill isn’t just about keeping it looking spick and span. It’s vital for food quality and hygiene. When cooking, grease, food debris, and unsightly residue accumulates. This grease buildup not only affects the taste of food, but it can also cause heat to be unevenly distributed, making it harder to cook meals properly... And, let’s be real − no one wants a greasy, dirty grill affecting the taste of their meals, right?
More importantly, grease buildup can breed harmful bacteria, potentially compromising food safety. Left unchecked, it can also lead to rust and wear, shortening the lifespan of your equipment. Why fork out more money for a new machine, when you can ensure yours runs well for as long as possible?
By keeping the grill clean, it will operate at its best, cooking food evenly and efficiently, saving on energy costs. Regular cleaning also prevents any greasy residue from flaking into your dishes, which could impact both the taste and presentation of your food.
In short, cleaning your commercial grill is a critical part of maintaining a safe, efficient kitchen and delivering high-quality, consistent meals to your clients.
Essential Cleaning Tools and Equipment for Grills
First up: To keep your commercial grill or griddle in good shape, you’ll need the right gear.
Essential cleaning tools include:
- A grill scraper – for scraping away the big stuff.
- A scrub pad – to get to the nitty-gritty.
- A griddle brick – which works wonders for stubborn spots.
- A grease trough – to collect and get rid of excess grease during cleaning (don’t forget about this).
Depending on your grill type, you might need extra tools. Cast iron grills are harder to clean, for instance. Using a gas grill? Invest in a brush with stiff bristles to clean the grates, and heat-resistant pads or gloves to protect your hands when cleaning hot surfaces.
A stainless steel griddle or chrome grill, on the other hand, will require gentler cleaning methods, so always use non-abrasive tools to avoid damaging the surface during cleaning.
A degreaser or cleaning solution is also useful for breaking down grease, while protective gloves keep you safe from hot griddle burns and protect your skin against harsh cleaning agents. Keep everything handy, so you’re not scrambling halfway through.
How to Clean a Kitchen Grill in 6 Steps

Follow these six simple steps to ensure a thorough, safe clean:
Step 1: Turn Off, Cool Down
Before you start, make sure the grill’s off and has cooled completely. Check the manufacturer’s guidelines to confirm the safe temperature range for cleaning. Typically, it’s between 120°C and 150°C. For gas grills, don’t forget to disconnect the supply to prevent any accidents − safety is key.
Step 2: Remove Excess Grease and Debris
Next, roll up your sleeves and get stuck in. Use a scraper to scrape off large chunks of food and grease, clearing the surface of any big pieces that might get in the way. To remove smaller debris, use a dry cloth.
Step 3: Apply Your Cleaning Solution
Once the surface has been scraped and wiped clean, a commercial griddle cleaner or a baking soda solution works wonders for stubborn grease and grime. Let it sit for a few minutes. This will loosen up any residue and make scrubbing much easier. For heavier grease buildup, you may want to apply a stronger degreaser, following the product’s instructions carefully.
Step 4: Scrub the Surface Thoroughly
Once the cleaning solution has had time to work, grab a griddle brick or scrub pad and get scrubbing. Work in sections, using a circular motion, to ensure you cover every part of the cooking surface thoroughly.
Note: avoid abrasive pads that could damage the surface.
Step 5: Clean the Grease Trough and Other Areas
Don’t forget the grease trough or any other nooks where grease may have stuck. Removing grease from these areas will help prevent clogs and ensure the grill continues to operate smoothly. Again, use a scraper or a damp cloth to clean these areas properly.
Step 6: Rinse and Dry
Once all areas are cleaned, rinse off any remaining cleaning solution with warm water. Dry the grill thoroughly to prevent rust or any residue that could affect the cooking process. Once completely dry, reassemble any parts that were removed and you’re good to grill again.
Notes on Cleaning a Restaurant Flat Top Grill or Gas Grill
Cleaning a flat-top grill or gas grill requires a little more attention to detail. For flat-top grills, focus on cleaning the grease trough as it can collect a lot of gunk. For a gas grill, take care around the burners − don’t let any cleaning solution get inside, as too much moisture can cause issues with gas flow. Use a soft brush to clean the burner grates so they’re clear of any grease buildup.
Pro tip: To avoid damaging sensitive components, always follow your manufacturer's guidelines.
Routine Maintenance Tips for Keeping Your Grill in Top Condition
As mentioned, a well-maintained grill boosts kitchen efficiency, improves food quality and ensures a safe cooking environment. That’s why regularly maintaining your commercial griddle or grill should form part of your kitchen’s food safety management system.
Below are some simple routines we suggest to form part of your cleaning schedule and keep your grill performing at its best:
Daily Maintenance
- Clean the cooking surface: Each day end, use a grill scraper to remove food debris and grease. Follow up with a grill brush or scrub pad to clean the surface thoroughly. Wipe down with a damp cloth and re-season the cooking surface with a thin layer of oil. Seasoning prevents rust and keeps the grill’s non-stick properties.
- Don’t neglect the grease traps: Empty and clean them daily to avoid overflow and fire hazards. Use hot water and a degreaser to remove any stuck-on food and oil.
- Inspect for wear and tear: As you do a quick clean, check the grill for any cracks or loose components. See to such issues early to prevent them from worsening.
Weekly Maintenance
- Deep clean the grill: Turn off and cool the grill, then disassemble any removable parts. Soak them in hot, soapy water, and scrub away any grime. Thoroughly clean the cooking surface and other parts with a heavy-duty grill cleaner, then rinse and dry before putting parts together again.
- Check gas lines: Inspect lines and connections for leaks by using a soapy water solution. Tighten any loose connections and replace damaged lines.
- Lubricate moving parts: Apply food-grade lubricant to knobs, valves, and any moving parts to ensure smooth operation.
Monthly Maintenance
- Inspect and clean burners for blockages or damage. Clean them with a wire brush and replace worn-out burners.
- Calibrate temperature controls: Temperature controls must be accurate for consistent cooking. If needed, consult the manual or hire a technician.
- Inspect electrical components: Check for wear or damage and replace faulty parts.
Common Mistakes to Avoid When Cleaning a Grill
As much as some might not want to admit it, even experienced cooks can make mistakes. When it comes to cleaning a flat-top griddle or grill, one common error is using harsh chemicals. These can leave a residue that affects food flavour and even damage the grill’s surface. Instead, opt for food-safe, degreasing solutions designed specifically for grills when you clean a griddle.
Also, don’t underestimate the power of a little elbow grease. Avoid relying solely on chemicals. A good scrub with the right tools can help you clean a commercial grill properly and keep your kitchen compliant with hygiene standards.
Another issue? Neglecting the grease trough. A full grease trough is both a fire hazard and a breeding ground for bacteria, so be sure to empty and clean it regularly.
