Cleaning nozzles question

I have two brand new of the cloud colored nozzles shown below. I hooked one up for the first time today and its only spraying out on one side at a 90 degree angle like its clogged. The other one Ive been using for a month now and is fine. I popped the screen out and don't see anything. Is there an easy way to clean these like letting them soak in something for a bit?
