That's right, Leigh Anne.  There is no need to clean your mirror routinely.  Only if it gets so dirty or spotted that it is interfering with the views at night should you attempt to wash it.  Bill is right.  I have had my 10-inch Dob for 8 or 9 years and have yet to clean the mirror.  One of these days I'll get around to it.

That is good!-Isn't there a Swiffer for primary mirrors? HA! 

Unless it's real bad I can't tell a clean from a dirty by use. George has the dirtiest mirror in the club and I defy anyone to see a difference, on the same object- side by side with a clean mirror scope.

Is there a quick and easy way to dust off the primary mirror?

The instructions for my Orion XT8 classic dob tell me to remove the primary mirror and soak it soapy water and alcohol and wipe clean with cotton balls. Sounds like too opportunities to screw up, scratch and/or drop my mirror. I'm scared.
