How to Unclog a Spray Paint Can: A Comprehensive Guide

Clogged spray paint cans can be a frustrating problem for anyone who enjoys DIY projects or professional painting. Imagine gearing up for a creative endeavor only to find that your spray paint won’t come out! Fortunately, there are several effective solutions to get your paint spraying again.

In this blog post, we’ll explore various methods and tools you can use to unclog your spray paint can and get back to your project. Whether you’re a seasoned painter or a weekend warrior, these tips will help you tackle that pesky clog with ease.

Understanding the reasons behind a clogged spray paint can is the first step in preventing it from happening again. Here are some common causes:

Dried Paint Buildup in the Nozzle

One of the most frequent culprits is dried paint that accumulates in the nozzle. When paint is left in the nozzle after use, it can harden and block the spray path.

Hardened Paint Inside the Can

Sometimes, paint can harden inside the can itself, especially if it has been sitting for a long time. This can lead to a lack of pressure and an inability to spray.

Clogged Spray Tip

The spray tip can also become clogged due to paint residue. If the tip is blocked, the paint cannot exit the can properly.

Improper Storage

Improper storage can lead to clogs as well. Storing spray paint cans in extreme temperatures or laying them on their sides can cause paint to settle in ways that lead to clogs.

How to Unclog a Spray Paint Can

Now that we understand what causes clogs, let’s dive into the various methods you can use to unclog your spray paint can.

Method 1: Using a Safety Pin or Needle

This method is straightforward and requires minimal tools.

  1. Remove the nozzle from the spray paint can.
  2. Inspect the nozzle for any visible clogs.
  3. Use a safety pin or thin needle to gently clear out any dried paint inside the nozzle opening.
  4. Blow through the nozzle to ensure it’s fully cleared.
  5. Replace the nozzle and test the spray.

Method 2: Soaking in Warm Water

Soaking can help dissolve dried paint and make it easier to clear clogs.

  1. Remove the nozzle from the spray paint can.
  2. Soak the nozzle in warm water for 10-15 minutes.
  3. Place the entire spray paint can in warm water for a few minutes to warm up the paint inside.
  4. Use a soft toothbrush to gently scrub the nozzle and remove any dried paint.
  5. Rinse the nozzle and blow through it to clear any remaining clogs.
  6. Reassemble the nozzle and test the spray.

Method 3: Using Carburetor Cleaner or WD-40

These products can help dissolve stubborn clogs.

  1. Remove the nozzle from the spray paint can.
  2. Attach the clogged nozzle to a can of carburetor cleaner or WD-40.
  3. Press down on the nozzle to spray the cleaner through it.
  4. Repeat step 3 until the nozzle is cleared.
  5. Reattach the cleaned nozzle to the spray paint can and test the spray.

Method 4: Blowing Air Through the Straw

Using air pressure can effectively clear clogs.

  1. Invert the spray paint can and press the nozzle to release any excess paint.
  2. Use an air compressor or canned air to blow air through the straw at the bottom of the can.
  3. Repeat step 2 until the clog is cleared and paint starts spraying again.

Method 5: Drilling Through the Clog

This method should be used as a last resort, as it can damage the nozzle.

  1. Remove the nozzle from the spray paint can.
  2. Use a 1mm drill bit to carefully drill through the clogged passage in the nozzle.
  3. Blow out any debris with compressed air or a blower bulb.
  4. Reattach the nozzle and test the spray.

  • Store the nozzle in a container of mineral spirits or paint thinner between uses.
  • Replace the nozzle if it becomes severely clogged or damaged.
  • Use the spray paint within a reasonable time frame to avoid long-term clogs
