do you know what's in it? likily dried wax. open the hood, disconnect the tubes and shoot some compressed air through it (if you don't have access to a compressor you can by a can of 'canned air' from a computer store) and give it a blast

 

List price of a nozzle is $7. Keep it in mind.

 

Depending on where you live it very well could be calcium deposits from hard water. Put some vinegar on the nozzle and let it set, then rinse it off, it will disolve the deposits. I have done it before and it works well. I also dilute it 50/50 with water to get hardwater spots off my boat. Works like a champ.

 

disconnected the tube and blew air through it from a high pressure nozel on my compressor...
