How do you clean the top part of the hatch? This is the part at the top you can reach only when the hatch is open. For me it is hard to reach from outside the car. Maybe I have to jump in the trunk and clean from there?

 

I don't think you want to just "hop" in. I recently visited a window tinting forum in which they chuckled about jumping into the back of a Z and hearing cracking noises. I don't think the fiber board cover for the spare tire is designed to hold a person.

The same holds true for the rear brace. It was not intended to be used as a seat and can break.
