I am building an arcade machine, and a good friend gave me a Mitsubishi 93sb crt monitor, which is great, but it has a "little" problem.
The screen coating, called G-WARAS, is cracked. It was cleaned with some substance that disolved the coating partially leaving it looking like a cracked window.

Do you guys know how to get rid of the coating completely? I have tried alcohol and acetone but both have no effect.

Thanks for your help.
 
Have you tried taking it apart?

Careful if you do, chances are there could be quite a bit of voltage still charged up even when its unplugged.
 
does this coating look like some sprayed layer directly on glass or does it have depth and its plastic scheet gued to screen?

if its scheet then you have to peel it off and to do so you must take front bezell off. depending on glue it might go easily or very hard. try searching for tips on removing gdm-fw900 ag coating if its plastic.u
 
Try ammonia water, where the concentration of ammonia is reasonably high.
I'll take no responsibility of the outcome :p
 
Get a x-acto knife and cute around the edge and peel it off. You might need rubbing alcohol to get some of the glue off. My CRT look fantastic without the stupid anti reflective coating. The only problem is the build up of anti static and so don't touch your monitor screen while it's on. You will get a big shock from it.
 
If there is someone with the same problem I found the perfect and easy solution: Metal polish, the one that comes already dissolved in cotton, its like magic half an hour later no signs of the original cracked coating.

Thank you all.
 
Any brand specifically? A dozen or so versions seem to exist that all have different chemical properties (FYI). :)
 
It was Aladdin Magic Cotton, it´s composition is 35% aliphatic hydrocarbons 10% aromatic hydrocarbons and soap. I am in spain so I cannot know if you are going to find that exact brand, the important thing is the aliphatic hydrocarbons nearing 50%, you just have to be careful with the paint in the frame of the monitor.
