How to Fix Wd40 Not Spraying

WD-40 is a popular and versatile lubricant and rust preventative that many rely on for various household, automotive, and industrial tasks. However, users often encounter issues where the spray nozzle becomes blocked or the product fails to dispense properly. This can be frustrating, especially when you need to lubricate or protect surfaces quickly. Fortunately, most problems with WD-40 not spraying can be resolved with a few simple troubleshooting steps. In this guide, we will explore effective methods to fix WD-40 that refuses to spray, ensuring you can get back to your projects smoothly and efficiently.

How to Fix Wd40 Not Spraying


Identify the Cause of the Spray Issue

Before attempting to fix your WD-40, it’s important to determine why it isn’t spraying properly. Common causes include clogged nozzles, dried-out product, or mechanical blockages. Here are some typical issues to consider:

  • Clogged Nozzle: Over time, debris, dirt, or dried lubricant can block the spray opening.
  • Dried Product: If the can has been unused for a long period, the contents may have dried, creating blockages.
  • Mechanical Malfunction: The spray mechanism itself could be faulty or damaged.
  • Pressure Loss: The can might have lost pressure due to leaks or punctures.

By understanding the root cause, you can target your fixing method more effectively.


Step-by-Step Solutions to Fix WD-40 Not Spraying

1. Shake the Can Thoroughly

Sometimes, the contents inside the can settle or separate, causing issues with spray performance. Shake the can vigorously for about 30-60 seconds. This helps mix the lubricant uniformly and can sometimes restore proper spraying.

2. Clear the Nozzle

Blocked nozzles are a common reason for spraying problems. To clear the nozzle:

  • Remove the spray nozzle from the can.
  • Soak the nozzle in warm, soapy water to loosen any dried residue.
  • Use a pin, needle, or safety pin to gently poke through the small opening and dislodge any blockage.
  • Rinse the nozzle with warm water and dry thoroughly before reattaching.

After cleaning, test spray the WD-40 to see if the issue is resolved.

3. Try a Reverse Spray Technique

If the nozzle appears clear but the WD-40 isn’t spraying, try the reverse spray method:

  • Remove the nozzle from the can.
  • Hold the nozzle upside down and spray a small amount of WD-40 onto a piece of scrap or paper towel.
  • This can help push out any debris stuck inside the nozzle or tube.

4. Use Hot Water or Heat

If the lubricant inside the can has dried or thickened, applying gentle heat can help loosen it. Be cautious to avoid overheating or puncturing the can:

  • Place the can in a bowl of warm (not boiling) water for a few minutes.
  • Alternatively, warm the nozzle with a hairdryer for about 30 seconds.

After heating, shake the can well and attempt to spray again.

5. Check for Mechanical Damage or Leaks

If the can is damaged or has lost pressure, it may no longer spray properly. Examine the can for punctures, dents, or leaks. In such cases:

  • If the can is punctured or severely damaged, it’s best to dispose of it safely and replace it.
  • If you suspect a leak, try to press the nozzle gently; if no pressure is built up, the can might be compromised.

6. Consider Repacking or Reusing the Product

In some cases, the spray mechanism may be irreparably clogged or broken. As a last resort:

  • Carefully transfer the WD-40 into a new, clean spray bottle designed for lubricants. Make sure the bottle is compatible and rated for such products.
  • This allows you to continue using the product without the original can.

Preventative Tips to Keep WD-40 Spraying Smoothly

To avoid future spray issues with WD-40, consider these maintenance tips:

  • Store the can in a cool, dry place away from direct sunlight and extreme temperatures.
  • Always shake the can thoroughly before use.
  • Use the product regularly to prevent it from drying out inside the can.
  • Clean the nozzle after each use to prevent buildup.
  • If the can has been unused for a long time, perform the heat or reverse spray method before use.

Summary: Key Points to Fix WD-40 Not Spraying

Encountering issues with WD-40 not spraying can be frustrating, but most problems are easily fixable with straightforward steps. Start by shaking the can to remix the contents, then clean or clear the nozzle using a pin or warm water. Applying gentle heat can help if the lubricant has thickened, and inspecting the can for damage will determine if replacement is necessary. As a preventative measure, store the can properly, clean the nozzle after each use, and shake well before spraying. By following these tips, you can ensure your WD-40 remains functional and ready whenever you need it, saving time and effort in your maintenance projects.
