Leave the Windex where it is. Never spray anything onto your monitor. If you need to clean it, use a dry soft cloth, or one that’s damp at most. Not dripping. And don’t use spit, probably. Actually, spit might be OK. Spit on your screen. Clean your screen by spitting on it, but don’t use cleaning chemicals. Spit on your mouse, too. Cover everything around you in your own saliva, but don’t use Windex.
