Is it safe to clean microwave convection oven with oven cleaner?
No, the best way to clean a microwave is to fill a plastic
container(suitable for microwave) halfway with water and place in
microwave on full power for about 8-10 mins, when finished
carefully remove container (will be very hot) and wipe out
microwave with a damp cloth, all grease and baked in food should
come off.
