Water got behind my laptop screen, there's a stain now

Knocked a glass over near it. Dried it off and it still works, but there's a cloudy patch in one corner that looks like a watermark under the glass. Will it dry out by itself?

Don't press on the stain to see if it moves, that can push the liquid further between the layers. And if any got near the keyboard, unplug the charger too. Leaving it off is the main thing, rice doesn't really do anything.

turn it off and leave it off for a couple of days, open to about 90 degrees somewhere warm and dry. no hair dryer on the panel, heat can make it worse. the stain is moisture sitting between the layers behind the lcd. sometimes it fades completely as it dries out. if it's still there after a few days, it's probably permanent and the fix is a replacement panel.
