Fw: (ATMoB:Discuss) Dirty 2" TV Everbrite Diag

Gary,
 
I forwarded your question to Dr. Clay Sherrod. He runs the Arkansas Sky Observatory and has been a tremendous source of information for a great many amateur astronomers. Here's the response I got.
 
Hope this helps,
Dave

Dave - no, I do not recommend anyone using the solution, or any solution that contains detergent for uncoated mirror surfaces which these diagonals are.....the BEST way to clean these is with a Kleenex (or many dry ones used in succession....) and PURE isopropyl alcohol rated at about 93% or better, then followed by a clean rinse-wipe with distilled and filtered water.
 
This would work for all mirrored surfaces that have NO quartz overcoating.  Regular Newtonian primary and secondaries are overcoated however and can actually be cleaned using "Simple Green" among other concoctions!!

Dr. Clay,
 
Would this person want to use the same method you've defined for corrector plates to clean his diagonal?
 
thanx,
Dave

Hi,

It looks as if the diag mirror on my everbrite is in serious need of cleaning.  Anyone have a good method for doing this?  Its not simply some dust on the surface. I guess over time this thing has collected a good amount of grime. I can notice the degredation, as some stars seem to get blurry and smeared in certain areas. My guess was maybe using cotton swabs and 90+% alcohol. As i've never cleaned it before, I wanted to make sure I didn't do anything wrong and ruin it.
