MacBook Air 2019 - 13"

Had keyboard replaced several years ago due to recall. Now works fine.
The Macbook gets stuck closed sometimes, just takes a little extra force to open. I have cleaned it many times to try and prevent this but still gets a little stuck.
I had stickers on the top of the computer that I have since taken off and thoroughly washed, but a faint outline is still visible where the stickers used to be, as seen in photos.
