Your BBQ grill is the heart of your outdoor cooking setup - but even the best grill won't perform well if it is dirty or neglected. Grease, food residue, and ash can affect flavour, airflow and even safety.
Here's how to keep your grill clean, efficient, and ready for every cookout.
Why Regular Cleaning Matters
- Better flavour: Old grease and carvbon buildup cause bietter smoke and flare-ups.
- Longer grill life: Cleaning prevents rust and corrosion.
- Even heating: Clean grates allow better heat transfer
- Safer cooking: Reduces flare-ups and grease fires.
STEP BY STEP CLEANING GUIDE
- Preheat and Burn Off Residue - Turn on your grill (or light your charcoal) and let it run hot for about 10-15 minutes. This loosens grease and burns off stuck-on food.
- Brush the Grates - Use a grill brush or a grate scraper to remove debris. PRO TIP: Avoid wire brushes that shed bristles - choose bristle free or coil-style brushes instead.
- Clean the Interior - Once the grill cools: Remove the grates and clean underneath. Scrape grease buildup from flavourizer bars or drip plates. Wipe down with warm, soapy water - NOT harsh chemicals.
- Empty the Grease Tray - Check the drip pan or grease tray - this area fills up fast. Line it with foil for easier cleaning next time.
- Wash the Exterior - Use a non-abrasive cleaner and a soft cloth to wipe stainless steel or enameled surfaces. A quick polish keeps your grill looking showroom-new.
DEEP CLEANING TIPS BY GRILL TYPE
Gas Grills
- Disconnect propane before deep cleaning
- Check burners for blockages (spider weds, grease).
- Inspect gas lines for leaks or cracks.
Charcoal Grills
- Empty ash after each use - moisture turns it corrosive.
- Remove leftover briquettes before storing.
- Apply a light coat of vegetable oil to the grates to prevent rust.
Pellet Grills
- Empty the burn pot and vacuum out ash regularly.
- Clean the temperature probes for accurate readings.
- Store pellets in a dry area to prevent swelling or mould.
Common BBQ Cleaning FAQS
Q: How often should I deep-clean my grills? Light clean after each cook; deep clean every 3-4 months or more often if you grill frequently.
Q: Can I use oven cleaner on my grill? Avoid it! Oven cleaner is too harsh and can damage finishes. Use grill specific degreasers.
Q: Whats the best way to clean rusted grates? Scrub with a wire-free brush, soak in vinegar, and re-season with oil before next use.
