If it is the Rustoleum brand with the fancy spray tops – they can’t easily be fixed. If the can is new then I would take it back to the store to get your money back. Three Options to Unclog a Spray Paint Nozzle: Before trying to unclog a spray paint can nozzle, put on a pair of safety glasses to protect your eyes just in case the nozzle moves as you work on it. You don't want to get spray paint in your eyes. 1. After each use, clear the spray valve on the paint can by holding the can upside down and spraying off until only clear gas comes out. 2. If that doesn't work, remove the valve and run very hot water over it to remove any paint. You can also soak it in nail polish remover for about a half hour. Then take the end of a pointy toothpick or straight pin and put tip into the holes on the nozzle to clean out the paint. Do both holes on the nozzle – the underside and the one on the side of the nozzle. Important:  Only clean a spray paint nozzle when it is removed from the can. NEVER stick a pin into the nozzle when it is still on the can. Place back on can, shake the can very well, really shake it so the paint is completely mixed and spray. If it doesn’t spray, hold the can upside down and try to spray. 3. If you have a few cans of spray paint in your paint supplies, try switching out the nozzles.  This usually helps get the can spraying again. TIP: Before I throw out used cans of spray paint I save the nozzle. I place them in a baggie and store it so I have plenty when I need to change a clogged one.
