Water damage on my keyboard - drying tea (about 100mL)?

I poured tea on my laptop keyboard last night. The tea has already penetrated inside but I've got almost everything out of it. But I have read that the laptop can break with a drop of residue. Now I wanted to know if someone knows how and how long I have to dry it?

I don't really know about it, but I would actually wait 1 day for a small amount
