Care and cleaning

General advice

Maintenance Period	Description
Daily	Clean gas cooktop as per following instructions.
Monthly	Remove all burner parts, and clean using a non-abrasive detergent. Rinse in cold water, dry thoroughly, and replace. Clean the ignitor carefully, using a toothbrush and methylated spirits.
Every 3-4 years	Contact your local authorised gas Service Agent to perform a thorough check on all gas components on the gas cooktop.

Before cleaning, you must ensure that the cooktop is switched off.
Clean the cooktop regularly – do not let stains become burnt on.
Allow the appliance to cool down before cleaning.
Avoid leaving acidic substances (lemon juice, vinegar etc.) on the surfaces.
The control knobs may be removed for cleaning but care should be taken not to damage the seal.
Do not clean cooktop parts in a self-cleaning oven.
Do not use a steam cleaner to clean any part of your cooktop.
For stubborn stains, see the ‘Cleaning chart’.

Enamelled parts

Clean the enamelled parts with a sponge and soapy water only or other non-abrasive products.
Dry preferably with a microfibre or soft cloth.
If acidic substances such as lemon juice, tomato sauce, vinegar etc. are left in contact with the enamel for a long time, they will damage the surface.

Stainless steel surfaces

Stainless steel parts should be rinsed with water and dried with a microfibre or soft cloth.
Dry thoroughly to avoid leaving water marks. For extra shine on stainless steel, use a stainless steel polish.
Clean brushed stainless steel in the direction of the grain.
For persistent dirt, use specific non-abrasive products available commercially or a little hot vinegar.

Regular use could cause discolouring around the burners, because of the high flame temperature.

Burners and trivets

You can remove and clean these parts with hot soapy water or other appropriate products - see ‘Cleaning chart’.
After cleaning, check that the burners and their flame spreaders are dry before replacing correctly.
It is very important to check that the burner flame spreader and the cap have been correctly positioned. Failure to do so can cause serious problems.

To avoid damage to the electronic ignition, do not try to light a burner without all burner parts correctly in place.

Replacing the burners

It is very important to check that the burner flame spreader and the cap have been correctly positioned (see Fig. 19). Failure to do so can cause serious problems.
Check that the ignitor (Figs. 19 and 20) is always clean to ensure trouble-free sparking.
In the models with the flame failure safety device, check that the probe (Figs. 19a and 20) next to each burner is always clean to ensure correct operation of the safety valves.
Both the ignitor and probe must be very carefully cleaned using a toothbrush and methylated spirits (Fig.16).

Cleaning chart

Cooktop part	Cleaning	Important
Trivets, burner caps	Hot soapy water and nylon scourer. Soak removeable parts in a solution of biological clothes-washing detergent. Mild abrasive cream cleaners. Fume-free or heavy-duty oven cleaners (follow manufacturer’s instructions).	Always allow cooktop parts to cool completely before cleaning them. Always apply minimal pressure with abrasive cleaners. Clean spills regularly before they become burnt on.
Burner parts	Hot soapy water. To clear the holes use a stiff nylon brush or wire eg straight-ended paper clip. Mild abrasive cream cleaners.	Reassemble the burner parts correctly.
Control knobs	Hot soapy water and a soft cloth.
Stainless steel base	Soak stains under a hot soapy cloth, rinse and dry thoroughly. Hard water spots can be removed with household white vinegar. Non-abrasive stainless steel cleaners. Regular use of a stainless steel polish will reduce fingerprints and other marks. Heavy soiling can be removed with fume-free or heavy-duty oven cleaner (follow manufacturer’s instructions).	Never use harsh/abrasive cleaning agents as they will damage the stainless steel finish. Chlorine or chlorine compounds in some cleaners are corrosive to stainless steel and may damage the appearance of your cooktop. Check the label on the cleaner before using. The graphics are etched onto the steel and will not rub off.
Enamel base	Use soft cloth or non-abrasive sponge and soapy water. Do not use abrasive products.	Clean spills regularly before they become burnt on.
Ignitors	Toothbrush and methylated spirits.	A dirty or wet ignitor will prevent the burner lighting efficiently.
Probe (in models with flame failure safety valves)	Toothbrush and methylated spirits.	A dirty probe may prevent the safety valve from working effectively.
