I was trying to remove my cat from my desk and she pooed on my display. It is a Dell UltraSharp (I think) 2208WFP. I know I shouldn't have used this method, but I put some Windex on a paper towel and cleaned it with that. Then I went over the whole thing with Windex and paper towel. I never shot Windex onto the display. What should I do now? The affected area kinda smells like poo.
