Does anyone have experience with cleaning the outer surface of a corrector plate on an Meade LX200.
I need to remove what appears to be finger marks and a build up of moisture marks ( ONLY SLIGHT Marks ) on the exterior.
At first I thought it may have been a small build up of mould, perhaps from packing the scope away too quickly after a nights observing.
But I cant tell what it is, and I hope I can remove the annoying marks with cleaning.
The manual says Isopropyl Alcohol and distilled water mixed with one drop of mild detergent.
Is this OK ?

Any help would be greatly appreciated.
