I am only using the microwave function. I have cleaned it as much as possible, but there is still some dirt that I couldn't remove, such as on the heater at the top of the oven and the cover of the microwave outlet, as well as paint peeling due to opening and closing the door. Please take a look at the images and make your decision. - Brand: SHARP - Model: RE-180KS - Functions: Microwave, Oven, Grill - Operation Panel: Digital display, Button type - Capacity: Approximately 18L - Heating Method: Microwave Thank you for looking.
