Try cleaning it with a 50-50 solution of 99% Isopropyl Alcohol and demineralized water.. The Isopro should take care of any residue/stick substance... I wouldn't advise using windex, it is likely to leave a fine filmy coating on your mirror which is likely to degrade the views/images.

Isopro should do the trick, failing that, it could be time for recoating.. How old is the mirror?? I wouldnt think the coatings would deteriorate in less than 4 or 5 years, that said, with peltier cooling, your mirror isnt exactly going to hold to the same standards as the usual 12" mirror...

Best of luck getting it sorted.

Alex.
