How to Clean a Gas Hob Properly: Grates, Burners and Everything Between
A gas hob has more moving parts than any other kitchen surface — grates, burner caps, ignition ports — and grease finds its way into every gap between them. Here's how to actually get it properly clean, without damaging anything or affecting how it fires up afterwards.
Before you start
Make sure every control is off and the hob is completely cool before removing anything. Lift the grates and burner caps off carefully — most gas hobs are designed for these to come away easily, though a few models need a screwdriver for the caps specifically. If your hob has a standing pilot light, turn off the gas supply at the valve before you start taking parts off.
Cleaning the grates and burner caps
Soak in hot, soapy water
At least 20 minutes for everyday grime — longer for anything genuinely built up. This alone loosens most residue enough that scrubbing afterwards takes minimal effort.
For stubborn, baked-on residue, a baking soda paste
Roughly three parts baking soda to one part water, worked into a thick paste. Coat the caps and grates, leave for 20–30 minutes, then scrub with a non-abrasive brush or sponge.
Rinse thoroughly and dry completely
Any leftover moisture in tight corners can cause issues once the parts go back on, so take the time to dry properly rather than reassembling while still damp.
If your grates are enamel-coated, they can usually go straight in the dishwasher — check your hob's manual to confirm before relying on this shortcut.
A note on cast iron
Uncoated cast iron grates are the one genuine exception to the soaking method above — prolonged water exposure can cause them to rust. If you're not sure whether yours are coated or seasoned, check the manual before soaking; when in doubt, a damp cloth with a mild abrasive cleaner is the safer approach over a full soak.
Clearing the burner ports
The small holes around each burner can clog with grease and debris over time, which affects how evenly the flame burns. Clear them gently with a straight pin or a fine needle, working carefully so you don't distort the opening. Avoid wooden toothpicks for this specifically — they can snap off inside the port and create a bigger problem than the one you started with.
Cleaning the surface itself
With the grates and caps removed, spray the exposed surface with a degreasing cleaning solution and let it sit for around 10 minutes on anything stubborn. Wipe clean with a damp cloth, using a plastic cooktop scraper for any areas where food has genuinely fused to the surface — never a metal blade, which can scratch it permanently.
Reassembling and checking the flame
Once everything is dry, replace the caps and grates, making sure each cap sits flush and doesn't wobble when you nudge it — a loose fit usually means it's not seated correctly. Turn each burner on briefly to check the flame looks even and consistent; an uneven or weak flame after cleaning is usually a sign a port is still partially blocked and needs another pass.

Frequently Asked Questions
How long should I soak gas hob grates and burner caps?
At least 20 minutes in hot, soapy water for everyday grime — longer, or a baking soda paste left for 20–30 minutes, for genuinely stubborn baked-on residue.
Can I soak cast iron grates?
Only if they're coated or seasoned — uncoated cast iron can rust with prolonged water exposure. Check your manual, and if unsure, use a damp cloth with a mild abrasive cleaner instead.
What should I use to clear clogged burner ports?
A straight pin or fine needle, worked gently to avoid distorting the opening. Avoid wooden toothpicks specifically — they can break off inside the port.
Why does my flame look uneven after cleaning?
Usually a sign one or more burner ports is still partially blocked. Clear them again and check the caps are seated correctly and sitting flush.
Are gas hob grates dishwasher safe?
Enamel-coated grates usually are — check your hob's manual to confirm. Uncoated cast iron grates should not go in the dishwasher.
