Seems to be a rather involved process. I'm not cleaning screens for users. Once they've got the device they clean their own screens. When it's returned the screen gets cleaned once with screen cleaning wipes then the device is stored until reissued.

This method adds a lot of time (cost) to the process. Unless I'm supporting very finicky high $ employees this won't get done because of the cost.

OTOH, for a home user it seems a good project for the folks who don't like having a smudged screen.
