Screen Problem that got oily after spraying it with universal degrease

Greetings,

My surface pro 2 has a fan problem, it has ridiculously bad noise so I tried to use Universal Degreaser for cleaning the fan without opening it, unfortunately the oil containing in spray got behind the screen, should I open the surface and change the screen ? or can I clean the oil away in other ways?

I can send a picture of the screen if you needed .

best regards Meroojan
