Problem Removing/installing Mirror Glass



Because the search function did not clarify for me, I am posting this new topic.

I have a problem with the left mirror: when I wash my car, water gets between the glass and the silver foil (I think) on the back of it and I want to see how I can solve this situation, but for this I have to take the glass off the mirror but I don't know how . Is the bottle clamped or stuck to something?

What should I do to take down the bottle safely, without breaking it?

The car is the one in the signature.

If you have any clarifying pictures, please post them (often a picture is worth much more than a scholarly description).

Thank you
