Care and cleaning

With attentive care and cleaning, your hob and oven will retain 

its looks and remain in good working order for a long time. We 

will explain here how you should care for and clean them 

correctly.

Notes

■

Slight differences in the colours on the front of the oven are 

caused by the use of different materials, such as glass, 

plastic and metal.

■

Shadows on the door panel which look like streaks, are 

caused by reflections made by the oven light.

■

Enamel is baked on at very high temperatures. This can 

cause some slight colour variations. This is normal and does 

not affect operation. The edges of thin trays cannot be 

completely enamelled. As a result, these edges can be 

rough. This will not impair the anti-corrosion protection.

Cleaning agents

Damage to the various different surfaces caused by using the 

wrong cleaning agent can be avoided by observing the 

following instructions.

When cleaning the hob do not use

■

undiluted washing-up liquid or dishwasher detergent,

■

scouring pads,

■

abrasive cleaning agents such as oven cleaner or stain 

remover,

■

high-pressure cleaners or steam jets.

■

Do not clean individual parts in the dishwasher.

When cleaning the oven do not use

■

sharp or abrasive cleaning agents,

■

cleaning agent with a high alcohol content,

■

scouring pads,

■

high-pressure cleaners or steam jets.

■

Do not clean individual parts in the dishwasher.

Wash new sponges thoroughly before first use.
