How to Unclog a Paint Sprayer

Share this Image On Your Site

A clogged paint sprayer isn’t a big deal. You can easily unclog it in a few simple steps.

Things you’ll need:


  • Drying cloths and paper towels
  • Solvent (water, denatured alcohol)
  • Gloves
  • A breathing mask
  • A fine brush

The process


Step #1- Disassemble the unit

Make sure that you read the user manual first. You don’t want to take something apart just to realize you don’t know how to put it together again.

Step #2 – Clean the nozzle

You can clean the nozzle in multiple ways. One of the most effective ones is to submerge it in water (or other solvents), leave it to rest for a couple of minutes, and blow air through the nozzle while it’s wet. If you cannot blow the paint out, feel free to use cotton buds or a needle to eliminate the residue.

Step #3 – Double-check

Before you start assembling the unit, make sure that you’ve eliminated the leftover paint from the inner side of the nozzle. Wipe the part with a dry cloth and finish up with dry towels. Make sure that you don’t apply too much pressure while polishing the nozzle because it’s a pretty sensitive and fragile component. You can use a fine brush to clean the nozzle as well.

Step #4 – Reassemble and Check if it’s unclogged

When you finish the unclogging process, put the unit back together. It’s advised that you refer to the user manual if you stumble upon any issues. Test the unit by squeezing the trigger and blowing air and paint on a piece of paper before you start painting again, just to make sure it’s properly unclogged.

If it still seems clogged, repeat the first three steps.

Step #5 (optional)

You can clean the whole unit instead of just the nozzle. The perfect moment to do it is during the second step of this guide. While it’s already disassembled, go ahead and clean every part with cotton buds, paper towels, or cloth. Make sure that you use fine materials for cleaning because a rough cloth can jeopardize the integrity of sensitive parts.

Always test the unit by squeezing the trigger and blowing the solvent on a piece of paper before filling it with paint and continuing your project.
