Aerosol Can Will Not Spray? Don't Toss it Just Yet!

02 Sep 2024

We've all been there. You're in the middle of a project, reach for your trusty can of spray paint, hairspray, or cooking spray, and...nothing. You push the nozzle again and again, but the aerosol can will not spray. Frustration mounts as you consider the half-finished project and the money seemingly wasted on a dud can.

But hold on! Before you toss that stubborn can in the recycling bin, there are a few troubleshooting tricks you can try. Often, the issue isn't a completely empty can but rather a simple clog or pressure problem that's easily remedied.

In this article, we'll explore the common reasons why your aerosol can might be refusing to cooperate and offer practical solutions to get it spraying again. We'll cover everything from simple clogs to pressure issues and proper storage techniques to prevent future frustrations.

Because let's face it, aerosol cans offer a level of convenience we've all come to rely on. From quick touch-ups on DIY projects to achieving that perfect hair hold, a malfunctioning aerosol can can throw a wrench in our plans.

So, before you resign yourself to a life without the ease of sprayable products, let's dive in and fix that aerosol can!

Troubleshooting an Aerosol Can That Won't Spray

Here are some common reasons why your aerosol can might not be spraying and what you can do about it:

1. Check for a Clogged Nozzle

This is often the culprit, especially if the can has been sitting unused for a while. Dried paint, hairspray, or other product residue can solidify in the nozzle, blocking the spray.

Solution:

Remove the nozzle by gently twisting or pulling it off.
Soak the nozzle in warm, soapy water for a few minutes to soften the residue.
Use a toothpick or a pin to gently clear out any visible clogs.
Rinse the nozzle thoroughly with warm water and dry it completely before reattaching it to the can.

2. Ensure the Can is Properly Pressurized

Aerosol cans work by using pressure to propel the product out. If the can isn't properly pressurized, it won't spray, even if it's full.

Solution:

Hold the can in your hand and feel for coldness. If the can is cold, it's likely pressurized. If it's at room temperature, it might not be.
Try warming the can up slightly by running it under warm (not hot) water for a few minutes. This can help increase the pressure inside.

3. Shake the Can Thoroughly

This might seem obvious, but sometimes the solution is as simple as giving the can a good shake. This helps mix the product and propellant inside for a consistent spray.

Solution:

Shake the can vigorously for at least 30 seconds to a minute, listening for the mixing ball inside to rattle freely.

4. Check the Expiration Date

Yes, aerosol cans can expire! Over time, the propellant inside can lose its effectiveness, resulting in a weak or nonexistent spray.

Solution:

Check the bottom of the can for an expiration date. If it's expired, it's time to dispose of it properly and get a new can.

Additional Tips to Keep Your Aerosol Cans Spraying

Store aerosol cans in a cool, dry place away from direct sunlight and heat sources. Extreme temperatures can affect the pressure inside the can.
After each use, hold the can upside down and spray for a few seconds to clear the nozzle of any remaining product. This helps prevent clogs.
Don't puncture or incinerate aerosol cans, even if they're empty. They are pressurized containers and can be dangerous.

Still No Luck?

If you've tried all these tips and your aerosol can still refuses to spray, it might be time to accept defeat. However, before you toss it, check if your local waste management facility has specific guidelines for disposing of aerosol cans.

Common Questions About Aerosol Cans

Here are some common questions people have about aerosol cans:

1. Why is my aerosol can sputtering?

This usually means the can is low on propellant. Try shaking the can well or warming it up slightly to see if that helps.

2. How can I tell if my aerosol can is empty?

Shake the can and listen for the mixing ball. If you don't hear it, the can is likely empty. However, even if you hear the ball, it could be low on propellant, so try the warming method mentioned earlier.

3. Is it safe to use an aerosol can that's been dropped?

If the can is dented or damaged, it's best to err on the side of caution and dispose of it properly. A damaged can could potentially leak or explode.

The Final Word on Stubborn Aerosol Cans

A malfunctioning aerosol can can be a frustrating experience, especially when you're in the middle of a task. However, before you add it to the ever-growing pile of things to replace, try these troubleshooting tips. More often than not, a simple clog or pressure issue is the culprit, and with a bit of patience, you can revive that aerosol can and get back to what you were doing. Remember to store your aerosol cans properly to prevent future issues and always prioritize safety when dealing with pressurized containers. Happy spraying!
