I got white out on my screen! Acetone took it off desk. How off my screen

Use of acetone on your screen is very likely to ruin it completely. If just plain water won't remove the whiteout, try a cleaner certified for LCD screens such as the one from Kensington. I've also seen mention that lemon extract works as may Goo Gone, but for either of those, use a very small amount on an inconspicuous corner of your screen first to make sure the solution doesn't damage the screen surface.

And of course whatever you use, don't use so much that it runs down inside your computer. That could easily lead to disaster.

Good luck.
