What kind of liquid do you have in them? Some times the stuff gums up the works. With hairspray (yeah I know not bloody likely that you have hairspray in one ) , I pop off the sprayer part and scrub it in hot water.

Hold on Z, have you seen him withouth a helmet?  He makes my head sweat and yet HE complains about the heat!

Pop them in a sink O hot water & soak them a while, while theyre underwater,, pump the things a bit & see if they start movin water, then use a bit of mineral oil & lube theyze guts up a bit,

I think theres a new spray cleaner out for cleaning spray cleaners its called spray clean spray.JOG is right I've found that you almost have to clean than with soap and water to keep them working.

I do what Z does... we must use the same kind of hairspray  

I bet some hot water will loosen most anything that would be sprayed from a bottle like that.  You might have to take apart the sprayer nozzle, and the hose, but I'm confident you can manage...

I just bought 2 new ones, empty, at the dollar store for (guess how much!) $1.00 each!...  Needed them for my plants, and couldn't find one under the sink that I felt could be cleaned well enough to not hurt the plants.  Didn't even think about them being so gummed up they wouldn't spray anyway!
   

being in the chemical business i can tell you from experience that the wrong squitter married to the wrong chemcial = the squiter seizes up - we have to buy one kind for solvents, another for cleaning solutions - at least 3 or 4 different ones based on what they will be used for all made out of slightly different klinds of plastics with different kinds of seals and different kinds of squitter guts......the problem is the basic squiter bottle at the store does say what it is made of so get pot luck.....no way to tell them apart unless you know thwe tricks of the trade and are willing to melt one to see how it reacts to tell what it is made from....not my bag but our chemist could tell you - he has to do all the testing and burning to determine which squitter will work with which product....major pain in the a$$$$$$$!
