A container can easily be tested for microwave "transparency":
Place the empty container on the turntable together with a glass of water and run the oven for one minute at maximum
power.
After one minute:
if the container is cold, it is "transparent" and can be used for microwave cooking,
if the container is warm or hot it is absorbent and must not be used for microwave cooking.
CLEANING AND MAINTENANCE
Before any cleaning or maintenance operation, disconnect the microwave oven
from the mains supply and allow it to cool to room temperature.
General Advice
Frequent cleaning prevents the formation of smoke and bad odours during cooking and also
sparking in the oven cavity and around the door seal.
Do not let food deposits or grease accumulate inside the oven cavity or on the door seal.
Make sure that the waveguide cover is kept clean at all times. Should food deposits or grease
be allowed to accumulate on the cover, sparking will occur and may damage your oven
invalidating the warranty.
Oven Door
Remove any food deposits and grease between the door seal and oven cavity using a damp
cloth, it is important to keep this area clean at all times.
Interior Walls
Remove any grease splashes from the oven cavity walls with soap and water, then rinse and
dry.
The door seal and oven cavity have to be particularly well cleaned to ensure the door will close
properly and to avoid sparking between the oven cavity and door assembly.
Do not use abrasive products such as scouring pads which will damage the surfaces of the oven
cavity and door.
Outer Surfaces
To clean the outside surface, use a damp cloth.
Avoid using abrasive products such as scouring pads that may damage the cosmetic surfaces.
Make sure water does not seep into the ventilation slots.
