What movie had a house of germaphobes and (maybe) clear slime?

I’m trying to figure out the name of a movie I watched around 10-11 years ago. It wasn’t a super popular film, but I remember a scene where the main character when to their friend’s house, which was covered in plastic. They had to go through a thorough decontamination before entering. I also vaguely remember a scene with a clear, slime/goo substance? Perhaps being passed out to people in the neighborhood in a container? I don’t believe it was a horror film or anything like that as I watched it in school.
