We know cleaning a flat top grill can be a real pain, especially after cooking a big meal. Whether you're trying to scrape off stuck food, wipe away grease, or remove dark stains, keeping your grill clean is important for safe cooking and making your grill last longer.
According to Steven Raichlen, author of "The Barbecue Bible" and host of Project Fire, "The biggest mistake people make is letting their grill get too dirty. A clean grill is essential for both food safety and flavor."
Just like washing dishes after dinner, cleaning your flat top grill doesn't have to be complicated. The trick is to clean it while it's still warm – not hot – and to use the right tools. You'll need:
- A grill scraper
- Paper towels
- Cooking oil
- Warm water
- Grill cleaner made for flat tops
- A clean cloth
Start by scraping off loose food bits, then wipe the surface with a damp cloth. For tough spots, use your grill cleaner and scrub gently. Once clean, put a thin layer of cooking oil on the surface to protect it from rust.
Remember to clean your grill after each use – this makes the job much easier and keeps your food tasting great. Think of it like brushing your teeth: a quick clean now saves you from bigger problems later.
Tip: Never use harsh chemicals or steel wool on your flat top grill, as these can damage the cooking surface and leave scratches that make future cleaning harder.

We've found that cleaning tips like scraping off food residue immediately after cooking and applying seasoning oil before and after use will extend your griddle top's lifespan considerably.

Let's look at what we should and shouldn't do when cleaning our flat top grill to keep it in top condition.
We'll walk through the essential steps that'll help maintain your griddle's cooking surface, including proper scraping techniques, steam cleaning, and seasoning.
Things to Do When Cleaning a Flat Top Grill
Proper cleaning of a flat top grill requires a systematic approach that combines immediate post-cooking maintenance with regular deep cleaning practices. By following the right cleaning procedures, you can maintain the grill's seasoning while ensuring excellent cooking performance and preventing the buildup of harmful residues that could affect food quality.
- Scrape debris immediately – Use a grill scraper to remove food particles while the surface is still warm, pushing waste into the grease tray.
- Apply steam cleaning – Pour warm water onto the hot surface to create steam, loosening stuck-on food.
- Use grill stone/brick – Work in circular motions with a pumice stone to remove stubborn residue and maintain surface evenness.
- Wipe clean – Remove all loosened debris with clean cloths or paper towels until the surface is completely clear.
- Season the surface – Apply a thin layer of high-heat cooking oil to protect the metal and maintain non-stick properties.
- Empty grease tray – Dispose of collected debris and grease properly after each cleaning session.
- Avoid soap usage – Skip soap during routine cleaning to preserve the grill's seasoning layer.
- Perform preventive maintenance – Regularly inspect for rust spots and address them immediately with deep cleaning when needed.
Things to Avoid When Cleaning a Flat Top Grill
When cleaning a flat top grill, using proper techniques and materials is essential to maintain its longevity and cooking performance. Incorrect cleaning methods can damage the cooking surface, compromise the seasoning, or even lead to permanent structural issues that affect heat distribution and cooking quality.
- Plastic scrapers and utensils – Metal scrapers are more effective and won't melt or leave residue on the hot surface.
- Back-and-forth scraping motions – Causes uneven wear and scratches that can trap food particles.
- Cold water on hot surface – Thermal shock can permanently warp or crack the griddle top.
- Soap during routine cleaning – Strips away valuable seasoning that provides non-stick properties.
- Delayed cleaning after cooking – Allows food debris to harden and become more difficult to remove.
- Abrasive cleaning pads – Can damage the cooking surface and remove seasoning.
- Chemical cleaners – May leave harmful residues and damage the griddle's surface.
- Incomplete drying after cleaning – Can lead to rust formation on the cooking surface.
- Excessive force when scraping – Can gouge or scratch the griddle top.
- Leaving oil pools on surface – Creates sticky residue and rancid spots when not properly cleaned.
