If the inside of your oven has an enamelled interior, the most effective cleaning method is a damp cloth while the oven is still warm. Also, oven cleaning agents suitable for enamel can also be used if required. If your oven has catalytic liners, they should not be cleaned. To remove any built-up deposits simply remove all oven trays and set the temperature to 240°C for one hour. If you aren't sure what type of interior your oven has, please refer to your instruction manual. Can't find it, don't worry you can download your manual here.
