How to Unclog Spray Nozzles

Written by kimbry parker | 13/05/2017

It has probably happened to most people. You go to use a can of hairspray, spray paint or a cleaning product and push down the nozzle, but nothing comes out. It can be incredibly frustrating to have a full can of a product but not be able to use it because of a clogged spray nozzle. Don't throw out the entire can just yet. Unclog spray nozzles quickly by using the proper products, tools and methods.

Remove the nozzle from the can or bottle. Use a rag to wipe off the nozzle as well as possible to remove any build-up.

Run the nozzle under hot water for a couple of minutes. Wipe the nozzle again with a dry rag. This may be all that is necessary to unclog the spray nozzle.

Soak the nozzle in rubbing alcohol if the problem persists. Fill a small bowl with alcohol and soak the nozzle for a couple of hours. For a spray-paint nozzle, soak it in paint thinner instead.

Remove the nozzle from the bowl and rinse it under water. Wipe the nozzle again with a rag. Scrub the nozzle with an old toothbrush for tough-to-remove build-up.

Stick a wooden toothpick carefully into the end of the nozzle that attaches to the can or bottle. Do not stick anything into the output end of the nozzle as this may damage the entire spraying system. Work the toothpick around to clear anything clogging the line.

Run the nozzle under hot water again. Wipe it down with a dry rag.

Use WD-40 or a similar lubricant if the nozzle remains clogged. Canned lubricants are usually equipped with a long, thin tube for spraying. Put the end of the tube directly on to the hole of the nozzle and spray a small amount of the lubricant.
