Fix Windshield Washer Nozzle on 2005 Mercury Mariner

I got some polish in a windshield washer nozzle and now it does not spray properly. I have worked a safety pin around the hole to clean it out with only partial success. How do I remove the nozzle to clean it?

The hose at the back of the jet needs to be removed and compressed air blown in from both sides. Usually cleaning the small nozzle hole with a pin works but sometimes they can be stubborn to clean.
