How to Clean a BBQ Grill Properly (Before It Ruins Your Next BBQ)

Most people don't clean their BBQ until something forces the issue, smoke pouring out on a low heat, food sticking to the grates, or a rusty hotplate they're embarrassed to use in front of guests. By that point, a quick wipe-down won't cut it.

Here's what's actually involved in a proper BBQ clean, what you can realistically do yourself, and where most home cleans fall short.

Why BBQs Get Worse Faster Than Ovens

A BBQ has more exposed surface area and less protection than an oven. Grease drips straight onto hotplates and burners, sits in open air, and gets rained on if it's not covered. Add in the fact that most people only clean the grates (not the hotplate underneath, the grease trap, or the burner tubes), and you get a buildup that compounds every summer it's ignored.

Left long enough, built-up grease under the hotplate can even become a minor fire risk, and blocked burner tubes cause uneven heat that ruins food long before you'd think to check the burners themselves.

What You Can Do Yourself

Grates. Heat the BBQ for 10-15 minutes to burn off loose residue, then scrub with a stiff wire brush while still warm. This handles the top layer most people think of as "the clean."

Hotplate. Once cooled slightly, scrape off residue with a metal scraper, then wipe with a mix of warm water and a small amount of dish soap. Avoid harsh degreasers directly on the hotplate surface if it's non-stick coated, they can strip the coating over time.

Grease trap and drip tray. Remove and empty this every few uses. It's the part people forget most often, and it's usually the source of any lingering smoky smell.

Where DIY Cleaning Usually Stops Short

Most home cleans handle the grates and maybe the hotplate surface. What gets missed almost every time:

• Burner tubes, grease and debris block the small holes that distribute gas evenly, causing hot spots and flare-ups

• Under the hotplate, where grease pools and hardens against the burner housing

• Side panels and control knobs, which collect grease residue from steam and splatter over time

• Hood and internal panels on enclosed BBQs, especially models with a lid

None of these are visible during a normal cook, so they're easy to ignore for years. They're also the parts that cause the most common BBQ complaints: uneven heat, flare-ups, and a BBQ that "just doesn't cook like it used to."

When to Call In a Professional Clean

It's worth booking a professional BBQ clean if:

• You can't remember the last time it was properly cleaned (not just the grates)

• You're noticing uneven heat or flare-ups during cooking

• You're getting the BBQ ready for a big event and want it done properly, not just wiped down

• You'd rather not deal with grease-covered burner tubes and hotplate housings yourself

At Oven and BBQ King, we strip BBQs back to the frame where needed, cleaning grates, hotplates, burner tubes, drip trays and housings with eco-friendly, non-toxic products. It's the difference between a BBQ that looks clean on top and one that's actually had every part addressed.

We also clean ovens, rangehoods, hotplates and microwaves, so if you're doing a full outdoor and indoor kitchen refresh, it's one booking instead of several.

The Bottom Line

A quick brush-down between cooks is fine maintenance. But a proper clean, the kind that actually resets a BBQ's performance, means getting into the parts most people never think to check. If yours hasn't had that kind of clean in a while, it's worth getting a free quote before your next big cook rather than after it goes wrong.
