If that's not working, try to spray a little de-greaser down there and let it sit. Rinse later.
This is a diesel?

I've had similar issues on diesel cars with that over-flow drain. I found most of the problem to be underneath the car where the rubber tube exits - - the spot seems to gather ever bit of sand/dirt imaginable. Take a look. The diesel fuel is oily and road debris sticks and builds up quickly.
