Using the knowledge I have gained from you lot, I washed my 10" mirror today.
Unfortunately it doesn't have a happy ending!
I used the washing up liquid/warm water soak for 15 minutes, cotton ball method.
The thing is, while I didn't drop the mirror or anything, The blemishes (see original pic) will not come off! And yes I did try in exasperation rubbing a bit harder than I should of (didn't hurt the surface though).
Looking closely it makes me wonder whether this is more of a corrosion thingy. We live close to the beach (salt air ?).
So my mirror really doesn't look much better than before. Possibly all caused by poor use/storage procedures. We do get a lot of due/frost depending on the season.
My scope is always kept in my colourbond gararge so I would have thought it may have less of a temperature difference than one kept in the house......I haven't been using the mirror fan. And quite often my viewing times are on a whim and the scope quickly gets set up and covers are off and i'm into it.
I have noticed the outside of the case gets wet to the touch some nights!
When I'm finished the big cap goes back on and the scope is stored in an UPRIGHT (mirror at lowest point facing up) position. Now in hindsight that is probably a daft thing to do because if the mirror is wet, storing it face up is bound to have particles (if it isn't a corrosive thing) drop and stick to it!
Opinions ?
