When cleaning a mirror use a cleaner which will completely evaporate...
All mirrors MUST have a protective coating!
If the mirror did not have a protective coating the reflective aluminum dust coating will oxidize and would loose it's reflectivity...a compact disc (CD) also utilizes the same type of technology..

My question is simple: does the primary mirror of the Celestron 8 have protective coating on the surface?
Good question...the mirror will have a protective coating however not sure which type of materials are used in the process..
