You got some REALLY BAD ADVICE.

You cannot remove the acetone. You have melted the plastic on the back of the screen. Acetone is a solvent for plastic.

If the area is very lightly affected, you may be able to hide the damage by using CAR BODY PASTE WAX as you would on a fine car finish. Car paste wax in a LIGHT application will fill the microscopically small pits in the plastic finish. Buffing the wax will probably make the dark finish on the back of the monitor look practically new.

The wax finish will not be as durable as the original plastic. Since it will sit facing away from viewers, it probably won't be noticed if you don't mention it. Car wax is tough and it should last as long as the monitor does.

You might have to buy a new case for the monitor or replace the whole monitor if your favour isn't appreciated by whomever you did this for.

Good luck.

    I ended up with sanding the hole plastic, so equal amount of light would path :) and it is a low resolution screen, so won't matter at all. – Catch.Me May 13 at 19:28

You can try to polish the rough plastic finish with a light abrasive such as jeweller's rouge or common toothpaste. Do this by hand. Do not take any short-cuts with power tools.

Search the Web for instructions to polish plastic. There is some instructions for polishing automobile headlight covers and for polishing convertible top windows. Use them for guidance and tips.
