If you ever have to remove the control panel, you'll be amazed to see how clear it becomes after just a bit of polishing! On mine, I had to remove the control panel as the door release mechanism was causing problems (the door wouldn't release) and I cleaned the display window at the same time. I don't remember exactly what I did to fix the door mechanism but it did solve the problem! On yours, you'll never need to fix that as there's a door handle instead of that release paddle.
