Fingernail

[albertshaw]

I use a lot of whiteout. Usually, scraping with the fingernail – or some soft plastic – would get it off.

If you monitor has textured plastic, then hard rubbing with a piece of cloth, water, and a lot of rubbing should get most of it of.

Whiteout is not made for markings. It is easy to get out. Easier than paint or marker pen.
