I purchased a 10.1" f 4.5 Coulter Mirror about 10 years ago. It has a small circle in the middle to aid in collimation. I was given instructions on how to remove it but I have misplaced them.

I am using the mirror on an optics bench and need to remove the circle. Does anyone remember the method for removing the circle? I would rather not recoat the mirror.

What solvents will not damage the coating? I have tried distilled water.
