Follow these simple steps for cleaning your microwave oven:

1. Ensure that the electric supply to the microwave oven has been turned off and the machine is unplugged from the socket before cleaning.
2. Wipe out the interiors and exteriors frequently and regularly to maximize efficiency.
3. Mop up spills and splashes as soon as they occur, as spilt food and splashes will slow down the cooking process the next time the microwave oven is used.

8. Never allow water or any cleaning liquid to enter any vents inside or outside the oven cavity.
