I have an older monitor, Samsung Syncmaster with Diamondtron tube. The inside of the cover glass has some gunk on it. Does the seam around the front of the monitor pry off bringing the cover glass with it, so I can clean the inside? There seems to be a couple of notches in the seam where a pry tool could be inserted.
The glass is the front of the picture tube, you can't clean inside it.
Don't even think about it. Its a sealed glass tube and the notches are probably where the tube is mounted in its case. Its not for nothing that it is called a Cathode Ray Tube Any gunk you can see on the inside of the tube is probably the phosphor coating deteriorating with age.

CRT's have three dangers. One is high voltage that can exist. Up to an in some older ones 10K volts and more. It will kill you even with the power off. Second is an implosion hazard. The tube if broken (and it is glass afterall) can cause glass and toxic dust to explode. Third is the toxic chemicals in the tube. My suggestion is to recycle it and get yourself a new green LCD monitor. A lcd monitor may even save it's cost on electricity and prevent dangerous emissions that may be present in a crt.

As Jefro indicated, do NOT disassemble the crt or TRY to remove the glass screen from the crt housing to clean the screen. Contains lots of dangerous stored energy. Have it serviced by some professional, or buy a CRT from craigslist usually for free.
Heck, buy an LCD for cheap nowadays
Good luck.
If the "glass" is a separate glass or plastic layer in front of the actual CRT, it might be removable if it merely exists to prevent scratching or dirtying of the CRT glass itself. I'd be surprised if something can actually get behind that layer and "gunk it up" (or the front face of the CRT glass itself), but humidity, cigarette smoke, and the like might. Obviously, if the "gunk" is behind the CRT's glass you won't be able to do anything except replace your display. As mentioned, be very careful opening up your display's case -- hazardous voltages may exist even when unplugged, and you don't want to scratch, damage, or break (shatter) that huge vacuum tube filled with toxic phosphors. If you're not sure that you can do it safely -- don't.
Try this Wolffe, it is harmless

My friend said this "The inside of the glass is coated with phosphors, if you wipe it it wont work anymore. "
try this if it works or not
try this if it works or not That only applies to LCD monitors . We are talking about CRT monitors here.

"That only applies to LCD monitors . We are talking about CRT monitors here."
Not offending or anything, but maybe you misread mistakely. :)"Works with any screen vulnerable to burn-in and image persistence; LCD, Plasma, Projector, CRT. "
You do not get stuck pixels and burn in is permanent on a CRT monitor, Thats what screen savers were invented for. Nowhere does that sight mention CRT montitors becasue ther is not a lot you can do with CRT monitors once they start going wrong.

To the first person who posted, its recommended just to replace your CRT or find a free crt on classified sites or from a donation store.
If you do get a LCD, not only its lighter, but uses ALOT of less power, thus less electric bill.
