I would clean the mirror with pure, distilled water. Alcohol would more than
likely smear the muck all over the mirror (as seems to have happened).
In fact it may be better to remove the mirror from its cell, wash it gently
in mildly soapy lukewarm water, and rinse thoroughly in several changes of
distilled water. Dont wipe the mirror because you may scratch it. Might
be a good idea to get some advice from Meade in any case.
What about the electronics? Did they survive? You have my sympathy - I hope
you manage to get it back in shape.
