How can we clean inside the oven door?

AEG Competence 5231 oven door has a glazed panel that has got dirty on the inside. Can this be cleaned or do I need a new door? I don't seem able to get into it.

not sure if it's the same model but on our Competemce if you pull the glass towards you with the door open it lifts out of the two black plastic clips in the section nearest the oven.

Got a more helpful person at repair shop: have opened the door. The double glazed panel is welded to it and needs the whole iner door panel replaced.
