Question scratches CRT TV
classicsamus87:
my crt has some scratches and i need a product to apply with fabric on the glass and remove the scratch
S. Petrukhin:
Try an immersion gel - it fills in cracks and scratches, has the same refractive index as glass and therefore hides defects-no change in density. It is inexpensive, does not require any special application, if it does not help , it is not a pity.

If that doesn't work (and the scratch is not deep) you can get abrasive polishing compound that will work on glass, but you will want a power tool to do it, a polishing wheel on an electric drill will work. It works by gently grinding away glass to smooth the surface so it takes a good deal of mechanical effort to accomplish.

What's the stuff they used in microscope slides? Canada Balsam?

Do they still make it? Sounds harmless and cheap.

The stuff I've used is called polishing rouge or jeweler's rouge, it comes as a bar that has a hard waxy consistency.
