Remove the glass panel to gain access to your iMac's internals.
-
Stick two suction cups to opposing corners of the glass panel.
-
Gently pull the glass panel straight up off the iMac.
In order to avoid unnecessary smudges and what not I covered the LCD itself with some plastic wrap while doing the hard drive upgrade. When I reinstalled it all I needed to do was blow off a few dust particles.
While you are at it, it is worth cleaning out dust within the case to help with cooling - particularly around the fans and vents.
For the screen I used a lens cleaner from my camera bag. These have very fine fibers and won't leave detritus.
Note that the front glass panel is quite light. When reassembling I found it impossible to get the LCD free of dust with the computer lying on its back. I had success with standing the computer up, tilting the LCD down as far as it goes, holding the glass panel upright in front of the computer (about 1 foot away), lightly spraying both the LCD and the back side of the glass panel with compressed air, and then attaching the glass panel (with the computer upright). It took me 5 tries before it was completely clean of dust once the front glass was on.
Although I do not advise it, you can substitute the suction cups with two strips of duct tape along the sides of the glass, with the tape attached to it's self in the middle of the strip

Good Instructions: Warning!, make sure all the screws are fully seated down prior to glass install. This is what happens when you don't:
At this stage and later handling the LCD I found thin cotton gloves helped to reduce smudges

My GPS unit's car mount suction cup worked nicely here - couldn't find any at the store and didn't want to wait for mail order!
Two cups would make it easier but one is fine if you place it in the center and are careful to pull the panel straight out.

Why use suction cups when some finger nails will do the job nicely, though a plastic spudger might work too. Start at a top corner. Prize the glass away from the case and leave finger nails in. Move the other hand along the top edge and then with finger spread peel the screen cover away. Be careful not to twist plastic I suppose, but I've had no difficulties.

3M Command Strip hooks in opposite corners is another fabulous option when suction cups are not available!

Tape works fine, here. Search for a YouTube video for a simple look-see.

I didn't have any suction cups, but my pencil sharpener (the kind that suctions to the table) worked great. I put it on the middle and lifted straight up.

For a quick 'n' dirty alternative "tool" for this step, take a look at IKEA's Stugvik suction hooks: they provide an excellent adjustable grip. Just used it to take apart an EMC2133. Cheers!

Suction cups usually available at Home Depot or Lowes, in the flooring section. (They're used to handle large ceramic & stone floor tiles.)
