A cooktop is a centrepiece of your kitchen and a long-term investment. With the right routine, you protect the finish, keep performance consistent, and stay safe. This guide covers daily care, deeper cleaning, and when to call a licensed technician.
What you’ll need
- Microfibre cloths and soft sponges
- Mild dish detergent; glass-ceramic cleaner for smooth tops
- White vinegar (for mineral film) and warm water
- Non-abrasive degreaser (as per manufacturer guidance)
- Purpose-made glass-ceramic scraper with replaceable blade
- Soft brush or nylon bristle brush
- Paper clip or soft bristle for burner ports (never toothpicks or needles)
- Gloves; good ventilation
Universal rules for every cooktop
- Check the manual first. Follow model-specific guidance to avoid voiding a warranty.
- Let surfaces cool. Clean only after components are safe to touch, unless handling sugar/plastic on a smooth top (see below).
- Wipe spills promptly. Sugary, acidic, or starchy spills harden and etch if left.
- Skip abrasives. No steel wool, scouring powders, or rough pads.
- Use minimal moisture. Liquids can seep into controls and cause failures.
- Dry thoroughly. Residual moisture leaves spots and streaks.
Gas cooktops
Safety prep
- Turn all knobs to Off.
- If removing parts, shut off the gas supply per the manual.
- Ensure the surface is completely cool.
After each use (1–2 minutes)
- Wipe the surface with a damp microfibre cloth and a drop of mild detergent.
- Dry the area to prevent water spots and rust on grates.
Weekly clean (10–15 minutes)
- Remove grates and caps. Soak in warm, soapy water for 10 minutes.
- Degrease the surface. Use a soft sponge and a non-abrasive degreaser.
- Unclog burner ports. Use a paper clip or nylon bristle to clear residue. Do not enlarge holes.
- Rinse and dry. Grates and caps must be fully dry before reassembly.
- Reassemble and test. A healthy flame is steady and mostly blue. Intermittent ignition, clicking that won’t stop, or yellow/orange tipping indicates an issue.
Monthly or as needed
- Lift top (where design allows) to remove crumbs and oil near igniters.
- Check rubber feet under grates; replace if worn to prevent scratching.
Annual
- Book a professional inspection of gas lines, connections, and valves. This is essential for safety and efficiency.
Never: soak or pressure-wash burner bases; use high-pressure steam near controls; use abrasive pads on enamel or stainless trim.
Induction cooktops
Induction uses electromagnetic fields to heat compatible cookware. The glass-ceramic surface doesn’t get as hot as radiant elements, but it can still scratch or stain.
Daily wipe (1–2 minutes)
- When the surface is cool, remove crumbs with a dry microfibre cloth.
- Mist a cloth with water and a drop of detergent; wipe, then buff dry.
Stubborn marks (3–5 minutes)
- Apply a small amount of glass-ceramic cleaner.
- Let it sit for 60 seconds.
- Gently work the area with a soft cloth in circular motions.
- Buff dry for a streak-free finish.
Melted sugar or plastic (handle promptly)
- Switch the element Off. While the area is still warm (not glowing), use a purpose-made glass-ceramic scraper at a shallow angle to lift residue.
- Wipe with cleaner and buff. Waiting until fully cold can make removal harder and risk etching.
Cookware checks
- Magnet test: a magnet should grab the base.
- Flatness: warped pans cause poor contact and scuffs; replace if rocking.
- Lift, don’t drag: to avoid fine scratches.
Glass-ceramic (radiant) cooktops
These tops heat via radiant elements. They look elegant but show rings and water spots if neglected.
Routine clean (2–3 minutes)
- When cool, wipe with a damp microfibre cloth and mild detergent.
- Rinse the cloth and wipe again; buff dry.
Burnt-on rings and grease (5–8 minutes)
- Apply glass-ceramic cleaner and allow a short dwell time.
- Use a scraper at a shallow angle to lift residue, working outward.
- Wipe clean and buff to restore sheen.
Mineral spots and haze
- Mist a cloth with a 1:1 vinegar and water mix; wipe and dry.
- Follow with a small amount of glass-ceramic polish if recommended by the manufacturer.
Avoid: powdered cleansers, generic razor blades, or coloured scourers that can transfer dye.
Ventilation and odours
Good airflow reduces sticky films and lingering odours. Run your hood on low during simmering and higher when searing. Wash or replace filters on the manufacturer’s schedule. Avoid aerosol overspray near controls.
Maintenance schedule
| Frequency | Tasks |
|---|---|
| After each use | Wipe spills; dry thoroughly. |
| Weekly | Degrease gas grates and caps; clean control panel; polish smooth tops. |
| Monthly | Clear burner ports; check grate feet; remove mineral film on glass-ceramic. |
| Annually | Professional inspection of gas connections and electrical components. |
When to call a licensed technician
- Smell of gas or a hissing sound
- Persistent yellow or lazy flames, soot, or scorching beneath cookware
- Igniter keeps clicking, won’t spark, or sparks continuously
- Cracked glass-ceramic top or exposed wiring
- Breaker trips linked to the cooktop
- Any leak suspicion or damage after impact
Turn the appliance Off, ventilate the area, and seek professional service immediately for suspected gas leaks.
FAQs
Can I use baking soda on a smooth top?
Light paste for greasy film is fine. Rinse completely and buff dry. Do not scrub with gritty pressure.
What cleaner is safest for induction glass?
Use a glass-ceramic cleaner and a microfibre cloth. Avoid powders and abrasive pads.
How do I remove melted sugar or plastic from a smooth top?
Switch Off and scrape gently while the surface is still warm using a purpose-made scraper, then clean and buff.
How often should I deep-clean gas burners and grates?
Monthly under normal cooking; more often with frequent frying or sauces.
Why is my gas flame yellow?
Usually incomplete combustion or blocked ports. Clean carefully; if the yellow flame persists, call a licensed technician.
Safety and warranty notes
- Follow your model’s manual for approved cleaners and tools.
- Keep liquids away from control openings and electronic touch panels.
- Do not use high-pressure steam or power washers; moisture can reach live components.
- If unsure at any step, stop and arrange professional service.
