mirror circles and cleaning my scope :)

hi everyone! i have the esprit 120 from sky watcher and i have 2 question!



1) Some glue (i guess...) has dried on my telescope and I want to clean it. the problem is that the glue is very close to the dew shield (and very close to the mirror...). i used wet wipe (with soap and water), and tried to clean all the glue! but i have a question. is the wet wipe with the soap and the water can enter through the dew shield into the mirror and harm the optics there? like you see in the image (the image that shows the telescope itself and not the mirror), the dirt is very close to the dew shield and also to the mirror, so i clean this area with a wet wipe, and also enter the edge of the wet wipe under the dew shied, because its very thin and maybe clean better the dirt... (i also tried to detach the shield but i didnt succeed...)



2) the attached images show some circles on my mirror at the edge of the mirror. what are these circles??? :undecided: :undecided:



thank you very very much!!!!!
