Made the mistake of spraying my keyboard with Oxyclean. Now keys malfunction?

I am now using my desktop. But with my laptop, when I press o, the 9key, Okey, and F10key all get pressed. When I press 1 in the number pad, 1, 2 and enter get pressed. When I press the +and= key, the +and=key and the num lock key get pressed.What should I do? My mother suggests airing it out because the inside is probably still wet. Any other views?
