Cleaning
In the interests of hygiene and safety, the hob should be kept
clean at all times as a build up of fats and other foodstuffs
could result in a fire.
Clean only the parts listed in this guide.
Clean with caution. If a wet sponge or cloth is used to wipe
spills on a hot surface, be careful to avoid steam burns. Some
cleansers can produce noxious fumes if applied to a hot
surface.
