Want to clean my Intes Micro MCT Primary

I had just picked up a real nice Intes Micro M6511, the scope is in real nice condition, no dents or scratches but the optics do seem that they need a cleaning. The corrector and secondary are real easy and I have already done them(secondary just needed to be blown off with a camera bulb) but the primary mirror seems to have more than just a few dust spots, more like dew marks, like it was taken outside then brought back in and not left open to adjust to the temps properly. I have never taken the back off one of these and wonder how its done, its the newer cream colored ota and has the vents by the corrector. The scope tests fine but I like all optical surfaces cleaned proper. Thanks Jim.

Best advice I can give you? _Leave the scope alone_. The marks will NOT affect images, and by cleaning you will risk doing more harm than good. If you insist, do NOT try to remove the rear cell or the primary. Remove the corrector and clean that way.
