My 10" Orion telescope sat in the garage till the mirror is filthy with dust, spider webs, and who knows what else. I've heard you should never touch them, but nothing short of a cleaning solution and tissue is going to do the job on this one. I was wanting to drag it out and check out Mars this week.

Any suggestions?
Thanks, Faesson. - How about it? Is soap and water ok? I had hoped to hear from an expert.
