How to Maintain a Gas BBQ

A gas BBQ is one of summer’s true essentials. They’re quick to heat, easy to use, and always ready to cook up succulent steaks, juicy burgers, and smoky vegetables. But even the best BBQs aren’t set-and-forget. Like any hard-working tool, they need regular care to stay safe, efficient, and ready for action.

But proper BBQ maintenance isn’t just about keeping things clean. It ensures even cooking, prevents dangerous grease flare-ups, and protects your grill against rust, wear, and costly repairs, keeping it in pristine condition for years to come.

Whether you're cooking on our Compact 2-Burner Gas BBQ or going big with the 6+1 Burner Gas BBQ, a few simple habits will keep your grill firing on all cylinders and wow your guests every time. Master the basics now, and you’ll spend the summer focused on what matters: delicious food, great company, and a grill you can rely on.

We know scrubbing a BBQ is a bit of a nightmare, but it’s the difference between a spluttering grill and one that’s ready to spark into life and turn simple ingredients into something special. Don’t worry; just a few minutes of regular maintenance delivers real rewards:

• Sharper performance – Clean grates mean even heat distribution, consistent searing, and fewer frustrating hot or cold spots.
• Safer grilling – Clearing away grease build-up lowers the risk of flare-ups and unexpected fires.
• Reliable ignition – A well-maintained BBQ fires up first time, every time.
  Longer lifespan – Protect your investment against rust, wear, and expensive replacements.

When you maintain your BBQ, you’re not just keeping it clean; you’re setting yourself up for better meals, safer cooking, and years of reliable grilling. It’s worth the effort!

A clean BBQ doesn’t just look the part; it cooks better, lasts longer, and saves you from scraping away layers of grease when you should be searing steaks. Keep this checklist handy and you’ll spend less time scrubbing and more time grilling.

Start where the action happens: the grates.

• Remove them and scrub with a sturdy grill brush to loosen carbon and burnt-on food.
• For deeper grime, soak in warm, soapy water for 15–30 minutes, then give them another scrub.
• Once dry, lightly coat lightly with vegetable oil to prevent rust and make the next clean-up easier.

Pro Tip: Clean grates while they’re still warm (not hot). The leftover heat loosens residue and makes brushing quicker.

The burners are the engine room of your grill; keep them clean, and everything else will run smoothly.

• Remove and gently scrub with a soft-bristle brush.
• Pay close attention to the tiny flame ports: if they’re blocked, gently clear them using a toothpick or fine wire.
• If you notice yellow flames or weak output, it’s usually time to clean them.

A dirty grease tray can cause fires, bad smells, and attract pests. Let’s prevent these from happening from the get go.

• Slide out the tray and use a plastic scraper or putty knife to remove grease build-up and debris.
• Wash thoroughly with warm, soapy water, rinse, dry, and reinstall.

Pro Tip: Cleaning monthly during peak season; it takes minutes and prevents headaches down the line.

This is the part most people forget, but it’s where grease loves to gather.

• Use a scraper to remove loose debris and carbon from the base and sides.
• Wipe down internal surfaces with a soft cloth or sponge and warm, soapy water – no harsh chemicals needed.
• Pay close attention to hidden areas under the burners and in the corners.
• Rinse and dry thoroughly to prevent corrosion.

Pro Tip: A showroom shine isn’t the goal here. It’s about clearing out the build-up to keep the BBQ cooking evenly.

The outside needs care too; it’s your BBQ’s first defence against the elements.

• For powder-coated or enamel finishes, wipe surfaces clean with a soft cloth and soapy water.
• Stainless steel? Use a microfibre cloth and stainless-steel cleaner (or a vinegar solution), wiping along the grain.
• Don’t forget the knobs, handles, and shelves; they’re often overlooked and quick to collect grime.

Once every component is clean and bone-dry, it’s time to rebuild:

• Refit the burners carefully, ensuring they’re properly seated.
• Replace any heat diffusers, set the clean grates back, and slide in the drip tray.
• Lubricate hinges, wheels, and moving parts with a spritz of WD-40.

Final Step: Once your BBQ is cool and reassembled, fit a heavy-duty weatherproof cover to protect against rain, grime, and time.

Here’s a simple schedule to keep your grill in prime condition:

✅ Stick to this and your BBQ will stay looking – and cooking – like new.

1. BBQ Won’t Ignite?

• Check the gas bottle – an empty tank is the simplest fix.
• Inspect the burners – grease or debris can block the flame path.
• Examine the igniter – if the ignition click is weak or missing, it’s time to replace the starter (a simple DIY swap).

2. Uneven Heat Across the Grill?

• Clean the burners – clogged flame ports often cause patchy cooking zones.
• Check burner alignment – if the tubes have shifted, realign them carefully to restore even heat.

3. Low Flame?

• Reset the gas regulator – sometimes regulators trip into safety mode. Turn everything off, disconnect the tank, wait 60 seconds, reconnect, and try again.

4. Yellow Flames or Strange Odours?

• Suspect incomplete combustion – usually caused by dirty burners or air-gas imbalances. Give the burners a thorough clean, but if the issue persists, have a professional service your BBQ to stay safe.

A gas BBQ isn’t just a summer purchase; it’s an investment in years of sizzling steaks, smoky ribs, and relaxed afternoons outdoors. But like any serious cooking tool, it needs a little TLC if you want it to last.

Here’s how to keep yours in peak condition for the long haul:

• Cover it properly – A heavy-duty, weatherproof BBQ cover shields your grill from rain, dust, UV rays, and bird mess that can corrode and stain over time.
• Store smart – If you’ve got the space, move your BBQ into a shed or garage during the off-season. A few dry months in storage can add years to its lifespan.
• Protect the surfaces – Wipe down exterior parts regularly to stop moisture, grease, and airborne grit from wearing away at the finish.
• Catch the drips – Always use a drip tray to stop grease from collecting in hard-to-reach places and accelerating corrosion.

Small habits, big rewards: a few minutes of care now can mean a decade or more of use, and no expensive repairs down the line.

Before you spark up the burners, make these checks second nature:

• Inspect the gas hoses and connections before every use – Look for cracks, leaks, or loose fittings that could cause serious issues.
• Give your BBQ room to breathe – Set it up at least one metre away from fences, sheds, decking, or anything that could catch fire.
• Never ignite with the lid closed – Trapped gas can cause dangerous flare-ups if you light it without ventilation.
• Always shut off gas at the cylinder after cooking – Closing only the burner knobs leaves pressurised gas in the system.

A few seconds of caution now can save you a world of hassle and ensures every barbecue ends the way it should: with empty plates and happy guests!

A gas BBQ that lights first time, heats evenly, and delivers perfect sear marks? That’s not luck – that’s a well-maintained grill doing what it was built to do.

And it doesn’t take much. Brush the grates. Empty the grease tray. Give it a wipe-down. Deep-clean when the seasons change. Small routines, big payoff: better flavour, safer cooking, and a gas BBQ that’s ready for every garden gathering you throw its way. Take care of your BBQ, and it’ll take care of every steak, skewer, and sunny Saturday to come!
