G'day. Getting back into the hobby again..... I have a 10" dob...Resides in my gararge in plastic. Decided to have a look inside and this is what I see !

Clean time ? What should I use?
This scope has a mirror fan which I must admit I tend not to use much. Could this be a dew problem? As quite often particularly in winter the outside case is wet when I pack her away.
Cheers . V8
