Understanding hob types and why methods differ
Electric hobs in office kitchens and retail staff rooms typically fall into three categories: coil/solid plate, ceramic-glass, and induction. Knowing which you have is essential to selecting safe, efficient cleaning methods.
- Coil/solid plate: Traditional elements with removable rings and drip trays (coil) or sealed cast-iron plates (solid). These are robust but prone to baked-on grease around rings and in drip trays. Liquids can migrate into controls if over-applied, so avoid flooding.
- Ceramic-glass: A smooth glass-ceramic surface with radiant elements beneath. Easy to wipe when maintained, but vulnerable to scratching and chemical hazing. Requires non-abrasive techniques and careful use of plastic scrapers.
- Induction: Also ceramic-glass on top, but the pan heats via magnetic induction. Spills can still bake on, especially sugary boilovers, and cleaning methods generally mirror ceramic-glass, with the same need to protect the surface.
The key differences:
- Mechanical scraping: Acceptable with a plastic scraper on ceramic-glass and induction at a shallow angle; avoid metal tools. On coil units, address carbon in drip trays and around rings mechanically after soaking. On solid plates, stick to wipe-and-dwell methods—no soaking.
- Chemistry: Neutral pH degreasers are the baseline across all types. Avoid powdered scourers or harsh abrasives on glass-ceramic surfaces, which can scratch and haze.
- Liquids management: Coil/solid plate units are more susceptible to liquid ingress into controls and wiring; apply solutions sparingly and never flood.
Safety first: a compliant, risk-controlled approach
Before any cleaning task, implement a short, documented safety routine that protects people, equipment, and compliance obligations.
- Isolate and cool:
- Switch off at the socket or isolator; confirm the hob is de-energised.
- Allow the surface to cool fully; never clean when energised or hot.
- Display temporary “Out of Use – Cleaning in Progress” signage.
- Personal protective equipment:
- Wear cut-resistant gloves suitable for wet work, eye protection, and non-slip footwear.
- Use heat-resistant gloves if residual warmth is suspected.
- COSHH and chemical control:
- Review COSHH/SDS sheets for any chemicals used; ensure all decanted containers are correctly labelled.
- Use only neutral pH, low-VOC, biodegradable detergents approved for food-prep adjacency.
- Never mix chemicals (e.g., bleach with acids or ammonia).
- Ventilation and spill control:
- Switch on local extraction and/or open windows to disperse fumes.
- Protect adjacent worktops, splashbacks, controls, and power outlets with towels or a washable barrier to prevent overspray and run-off.
- Equipment check:
- Inspect scrapers to ensure edges are intact; damaged blades can scratch glass.
- Verify that electrical components and controls are sealed and undamaged before you begin.
Step-by-step cleaning protocols
Daily routine (all hob types)
1) Prepare:
- Isolate power and confirm cool to the touch.
- Remove loose debris with a dry microfibre cloth.
2) Clean:
- Lightly spray a neutral pH degreaser onto a microfibre cloth (not directly onto controls or elements) and wipe the surface, focusing on fresh spills.
- For edges and around controls, apply solution to the cloth rather than the surface to avoid ingress.
3) Rinse and dry:
- Wipe with a damp cloth to remove residues.
- Buff dry with a clean microfibre to prevent streaks and hazing.
Ceramic-glass and induction: removal of carbonised spots
1) Pre-treat:
- Mix a paste of warm water and bicarbonate of soda.
- Apply a thin layer to the cooled, affected area. Allow 5–10 minutes dwell time to soften residues.
- Maintain ventilation.
2) Lift deposits:
- Holding a plastic hob scraper at a shallow angle (about 30 degrees), gently push under the softened residue, working away from yourself. Do not gouge or lever at steep angles.
3) Clean and finish:
- Wipe away loosened material and paste with a damp microfibre.
- Apply a small amount of neutral degreaser if needed; avoid abrasive pads and powdered scourers on glass.
- Rinse thoroughly and buff dry to a streak-free finish. Replace any protective silicone bumpers if fitted.
Coil/solid plate units: deep cleaning focus
1) Disassemble (coil type):
- Carefully lift out the rings and remove drip trays. Do not disturb wiring. If in doubt, consult the manufacturer’s instructions.
2) Soak components:
- Place drip trays and rings in a sink or tub with warm water and a measured dose of neutral detergent or a bicarbonate solution. Allow 15–20 minutes.
- Agitate with a soft brush or non-scratch pad as needed.
3) Clean the hob body:
- Wipe the hob top with a lightly dampened microfibre and neutral degreaser, taking care around the element sockets and controls to avoid liquid ingress.
- For stubborn residues on the enamel or steel top surface, use the bicarbonate paste technique and a plastic scraper.
4) Rinse, dry, and reassemble:
- Rinse components, dry thoroughly to prevent rust, and refit. Do not use steel wool on visible surfaces; it leaves scratches and can shed particles.
5) Solid plate care:
- Clean plates with a lightly damp microfibre and neutral degreaser, then dry immediately. Do not soak. Avoid oils or treatments unless explicitly recommended by the manufacturer.
Common pitfalls to avoid
- Do not use abrasive pads, powdered scourers, or metal scrapers on ceramic-glass.
- Do not flood surfaces; avoid liquid ingress into control knobs, element sockets, or electrical housings.
- Do not attempt to clean while hot or energised.
- Do not ignore sugary spills; caramelised sugars can etch and discolour glass if left.
Prevention, environmental best practice, and routine oversight
Prevention in shared spaces
- Spill-response guidance: Post a simple instruction near the hob: “Allow to cool, wipe immediately with a damp cloth, report heavy spills to Facilities.”
- Correct cookware: Use flat-bottomed, correctly sized pans that match the heating zone. Overhanging or undersized pans increase boilover risk and waste energy.
- Avoid sugary boilovers: Encourage lower heat settings for simmering and use lids to control splashes; monitor sweet sauces, porridge, and syrups closely.
- Visible rota and signage: Maintain a clearly displayed daily cleaning rota with responsible persons and times, plus “Clean After Use” reminders for staff.
- Weekly inspections: Facilities teams should record a quick weekly check for residue build-up, damage to surfaces, worn seals, and proper signage in place.
Environmental best practice
- Low-VOC, biodegradable products: Specify detergents with verifiable eco credentials suited to kitchen-adjacent use.
- Measured dosing: Use dilution control or pre-measured dosing caps to prevent overuse and reduce environmental load.
- Refillable bottles: Adopt durable, refillable spray bottles with clear labels to reduce single-use plastic and support COSHH compliance.
- Responsible waste segregation: Dispose of used cloths and pads according to site policy; segregate recyclables, and never pour concentrated chemicals to drain. Lightly soiled rinse water from neutral detergents can usually go to foul sewer in line with local regulations.
Compliance and risk control
- Equipment safety: Keep liquids away from controls and cable entries. Never pry or disassemble electrical components beyond routine removal of rings and trays on coil units.
- Chemical storage: Store cleaning chemicals in a locked, ventilated cabinet, away from food and heat sources. Maintain up-to-date COSHH assessments and staff training records.
- Documentation for quality assurance: Record daily cleans, weekly inspections, and any corrective actions. Photo logs are useful for trend analysis and audit readiness.
- Escalation criteria: Define when issues are beyond in-house scope (heavy carbonisation, repeated boilovers causing odours, or damage requiring parts).
When to call specialist cleaners
Specialist intervention is recommended when:
- Heavy carbon build-up resists safe in-house methods, or residues risk etching glass.
- Time-constrained, out-of-hours deep cleans are needed to avoid disruption to operations.
- The task is integrated with wider kitchen hygiene, appliance cleaning, and ventilation maintenance, requiring coordinated access, trained operatives, and method statements.
For higher-risk or multi-site portfolios, appointing an accredited contractor ensures consistent standards. Look for companies with ISO 9001 (quality), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety) certifications, plus SafeContractor approval and membership of professional bodies such as BICSc.
