Do not spray the cleaner onto the front of the tube, spray it on your
cleaning cloth and then wipe the face of the tubes. Have the sets turned off
to avoid any possiblity of static shock from the set. Generally the material
referred to will do a nice job on also cleaning the cabinets.

Windex (the ordinary glass-cleaning kind) is perfectly safe. It's even
safe
to use on precision coated optics if you don't do it every day. Unless
there's a delicate anti-reflective coating, you have ABSOLUTELY nothing to
worry about. If there's an anti-reflective coating, you can still use
Windex as long as you don't do it too often. If you need to clean a
delicately coated piece of glass every day or two, half Windex and half
distilled water is a good cleaner.

Clear skies,
