Dirt around the screen

I've had my pixel 2 xl for a few months now. I've found that a lot of dirt is getting stuck in the speaker and around the edge of the phone (in between the screen and the back). Has anyone else had this problem & how did you clean it please? It's such a small space that I wouldn't be able to use anything to pull it out, but it's all I can see and it's very annoying. The only thing I can think of is taking the phone apart. Thanks in advance.
