Removing the microwave door

Question

We have the British version of the above Neff oven. We had an accident with some hot gravy which entered the cavity between the two glass panels which make up the oven door. I asked Neff UK how to split the door so that I could clean up the glass inside. They said to book a service call. I need to remove the door from the oven casing so that I can dismantle it and clean it. The door appears to be screwed together with torx bolts. Question (a) Is it safe to split the door? (b) Is it easy to separate the door sections once the door is off? I can get the oven out of its cabinet and have already renewed the oven light. Any advice would be welcomed. Thanks.
