How to clean a portable gas stove: safe, correct cleaning steps

After every hotpot or barbecue meal, a portable gas stove is usually left with spilt broth, grease and food scraps. Left for a long time, the residue blocks the flame ports, the flame burns unevenly, the stove becomes hard to light and it deteriorates quickly. Knowing how to clean a portable gas stove properly makes it last longer and helps you spot damage early. The most important thing is to clean it without letting water or cleaning products get into the parts that must not get wet.

Before cleaning: remove the canister and let the stove cool

1. Turn the knob to the off position and wait until the flame is completely out.
2. Release the locking lever, remove the gas canister from the stove, fit the cap and put the canister in a well-ventilated place, away from where you are cleaning.
3. Wait until the stove has cooled completely: hot pot supports and burners can cause burns, and cold water on hot metal can easily damage the coating.

Never clean the stove while the gas canister is still fitted.

Daily wiping after use

• Use a soft, slightly damp cloth, wrung out thoroughly, to wipe the top of the stove, the body and the knob.
• Grease marks: wipe with a cloth dampened with a little diluted washing-up liquid, then wipe again with a clean damp cloth and a dry cloth.
• Do not use steel wool or harsh cleaning products; scratched paint or enamel will make the stove body rust quickly.
• Do not spray water or aerosol cleaning products directly onto the stove.

Cleaning the pot supports and drip tray

Many models have removable pot supports or drip trays (see the manufacturer’s instructions). Removable parts can be soaked in warm water with washing-up liquid, scrubbed with a soft brush, rinsed and left to dry completely before being refitted. Parts fixed to the stove body should only be wiped with a damp, well-wrung cloth.

Clearing the burner ports properly

1. Use a soft, dry brush (an old toothbrush will do) to brush gently around the burner and remove residue.
2. If a port is blocked, gently clear each port with a bamboo toothpick; do not poke hard with nails or hard metal objects that could deform the flame ports.
3. Brush the residue outwards, without letting it fall inside the stove.

If the flame is still weak or red after cleaning, the cause may lie elsewhere — see weak or red gas stove flame.

Places where water must not get in

• The canister compartment: standing water rusts the canister locking mechanism, the lever and the spring.
• The igniter and electrode: if they get damp, the stove will click without lighting — see portable gas stove won’t light.
• The valve assembly and control knob.

If water does get in, wipe the outside dry and leave the stove to dry naturally in a well-ventilated place until it is completely dry before fitting a canister. Do not use a flame to dry the stove.

Check the canister compartment and seal

• Wipe away dust and residue where the canister sits and from the canister holding mechanism (many models use a magnet); do not let foreign objects get stuck inside.
• Look at the rubber seal where the canister valve connects: it should be intact and elastic, not cracked or hardened.
• Try the canister locking lever: it should move smoothly and close firmly.

Damage found while cleaning: stop using the stove immediately

Stop using the stove and contact the seller if you find a cracked or missing seal, a loose canister locking mechanism, a dented or rusty canister compartment, a cracked burner, scorch marks around the canister compartment, or a smell of gas when a canister is fitted. Do not improvise replacement parts. If the stove is under warranty, take it with its warranty card to the place of purchase or call the warranty hotline printed on the card; if you need to replace the stove, see choosing a portable gas stove.

Storing the stove after cleaning

Only put the stove away once it is completely dry, in its carry case if it has one, and keep it in a dry place. Store gas canisters separately and do not leave a canister in the stove — see how to store butane canisters.

If your stove holds the canister in a separate box connected by a hose, see how a canister-box portable stove is built to learn which points on the hose and canister box deserve attention each time you clean and store it.
