removing corrector plate on SCT

My used SCT has a lot of dust on the inside tube walls and corrector plate. I'd like to remove the glass and clean the dust from the side walls, and blow it off the corrector plate with a photographer's manual blower bulb. I don't intend to touch the mirror or corrector plate surfaces.
Should I remove the corrector plate? Is it difficult to replace? How fragile is it, compared to windowpane glass? What pitfalls and problems can I avoid, and still get rid of some of the dust?
Thanks, Sebrin

Unless it's super dusty don't bother. Most dust has little optical effect and the risk to damage to the corrector is to great durring removal it's usually not worth it.

Point the scope at a normal day time scene, take
the eyepiece out, and look in the back opening.
If you can't see the dust looking through the back
I'd leave it alone. Shining a flash light through
the front does not tell you anything useful about the
amount of dust.

The corrector plate is very similar to window glass,
and just as fragile. Maybe a little thicker.

I've worked on a couple Celestrons where the corrector
is stuck in place by some adhesive -- the shims they
use are slightly sticky. Sometimes you can loosen it up
with a little prying (using a tooth pick) or by warming
up the scope. I've also seen a couple with big chips
in the corrector edge (not mine thankfully) where
people have used a screwdriver to pry at the corrector.

I guess my bottom line is that you probably don't need
to clean it. And otherwise consider sending it to the
factory. While many people have successful worked on
these, many others have made a big mess.

Thanks for the comments and feedback. The dust isn't apparent looking through the rear of the telescope, so I'll live with the bit I saw with a flashlight, looking from the front. I won't remove the corrector plate.
What convinced me is finding out about the shims, the adhesive, and the replacement of all the optics if something goes wrong. Without the responses to this forum, I would only have discovered these details, most likely, too late.
Thanks a lot, Sebrin
