The rubbing alcohol won't damage the keys in any way? I was always told to keep rubbing alcohol away from computers.
Rubbing alcohol (I think), will remove the finish on your keyboard. It will not damage it, but since it is so strong it will remove all the wax etc. in the finish and make your keyboard not look like new. As it does for other things, like finish on wood, rubber, plastic, leather.
There is a way you can remove the keyboard panel on most laptops. I would look that up on your model. And rinse that keyboard panel with water. And check your for any damage inside the laptop. Be careful not to void your warranty if you have any.
