Think your grill’s clean? You might be making these common mistakes without even realizing it. From bristle hazards to skipped steps that lead to flare-ups, here are the top five cleaning mistakes and how to avoid them.
🔥 1. Cleaning While the Grill is Cold
Sure, it seems safer to clean once everything’s cooled down. But here’s the problem grease and food residue stick harder when cold.
✅ The Fix:
Turn the burners to high for 10–15 minutes before cleaning (or light some coals if you’re using charcoal). Heat softens up grime, making it much easier to remove. After a quick preheat, scrub away with a grill brush while the grates are still warm, not blazing hot, just warm.
🧼 2. Using the Wrong Brush
If you’re still using an old metal bristle brush, it might be time for an upgrade. Loose bristles can break off, stick to grates, and even end up in your food which is more common than you think.
✅ The Fix:
Use a bristle free grill brush or a coiled stainless steel model that won’t shed. These are safer and just as effective.

💧 3. Not Cleaning the Drip Tray
This is the most overlooked part of the grill and the one most likely to cause a grease fire. All that fat and gunk drips down during cooking and collects in the tray.
✅ The Fix:
Check your drip tray every few uses. Empty it. Scrape out buildup. If it’s disposable, replace it. It only takes a minute and can literally prevent a fire.
🙈 4. Forgetting the Lid & Inner Walls
Out of sight, out of mind until flakes of burnt gunk fall onto your food. The inside of your grill’s lid and firebox walls slowly build up carbonized residue over time.
✅ The Fix:
Wipe down the lid and inside walls during each deep clean. You don’t need to make them spotless, but removing the top layer of grease goes a long way toward cleaner cooking.
❌ 5. Using Harsh Chemicals
Spraying your grill with heavy duty oven cleaner might feel like a power move but it can ruin the finish, leave behind toxic residue, and even damage components.
✅ The Fix:
Use food safe, non toxic grill cleaners made for BBQs. Many are plant based, effective, and won’t leave behind harmful fumes.
