Regularly cleaning your spray paint nozzles is a great way to keep the cans from becoming clogged. If you've ever been curious about how to effectively clean your spray paint nozzles, it may interest you to learn that it can be a very simple undertaking.

Step 1 - Soak the Nozzle in Paint Thinner

In some cases, a spray paint nozzle can be successfully cleaned using nothing more than paint thinner. Begin this step by removing the dirty nozzle from your spray can. This is often a simple matter of twisting the nozzle off and shouldn't require the aid of any tools. Once the nozzle has been detached from the spray can, pour some paint thinner into a small bucket or an expendable cup and proceed to soak it. When performing this step, take care not to soak the dirty nozzle for more than two hours, as it is liable to disintegrate. If a paint thinner soaking fails to adequately loosen the dried paint, proceed with the next step.

WARNING: Paint thinners are usually toxic, so check ingredient and safety tips before using it.

Step 2 - Use Your Safety Pin

If your nozzle is still covered in bits of dried spray paint, you'll need to incorporate the aid of a safety pin. After drying off the freshly soaked nozzle, use your safety pin to gently scrape away any remaining paint, taking care to pay special attention to the center of the nozzle. This can be a fast and effective way to clean or unclog a spray paint nozzle; however, if your nozzle is still not completely clean after performing this step, move on to step three.

Step 3 - Apply Your WD-40

If all else fails, WD-40 can prove very useful in cleaning and unclogging spray paint nozzles. To perform this step, simply spray your WD-40 directly into the dirty nozzle. This should loosen up any dried bits of paint that are still clogging the opening. Once they have been successfully loosened, use your safety pin to scrape the weakened bits of paint off. After your spray paint nozzle has had ample time to dry, reattach it to the can and store appropriately.

Step 4 - Prevent Future Clogs

Now that your spray paint nozzle has been properly cleaned, you'll need to take a few simple steps to prevent any future clogs. First off, make a point of holding the spray can upside down and spraying a small amount of paint after every use. Next, use an expendable cloth to gently wipe the nozzle clean. As an additional precaution, try placing a safety pin into the center before proceeding to store your paint. This will play an important role in keeping your nozzle open.

Lastly, make sure to store your spray paint in the type of climate recommended by the packaging. Depending on your storage area's temperature, the consistency of your spray paint can become overly thick or runny.
