When the plastic tip of a spray-paint can gets blocked, simply pull the nozzle tip off and put it on a can of WD-40. Give it a spritz or two, and put it back on its paint can. If it still doesn’t work, repeat the process, and spray WD-40 over the exterior of the nozzle. Repeat as necessary. For stubborn nozzles, use the red tube that comes with each can of WD-40 to focus the solution into both ends of the paint nozzle. The combination of pressure and penetrating oil will likely free up the nozzle and keep you from having to throw out usable paint.
