How to Clean Paint Gun with Dried Paint?
Cleaning a paint gun with dried paint can be a challenging task, but it’s essential to remove all residue to ensure the paint gun functions properly and efficiently. Dried paint on the gun’s surface can cause clogs, stuck valves, and reduced airflow, leading to poor painting results. In this article, we’ll provide step-by-step instructions on how to clean a paint gun with dried paint.
Why Cleaning a Paint Gun with Dried Paint is Important
Before we dive into the cleaning process, it’s essential to understand why cleaning a paint gun with dried paint is crucial.
- Prevents Clogs: Dried paint can accumulate in the paint gun’s passages, creating clogs that can be difficult to remove. Regular cleaning helps prevent clogs and ensures smooth paint flow.
- Maintains Airflow: Dried paint can also block air passages, reducing airflow and affecting the paint gun’s performance. Cleaning the air passages ensures proper airflow and optimal paint flow.
- Reduces Waste: Cleaning the paint gun after each use helps reduce paint waste by removing excess paint and preventing it from hardening on the gun’s surface.
- Prolongs Paint Gun Lifespan: Regular cleaning can extend the life of the paint gun by preventing rust and corrosion caused by dried paint.
Materials Needed for Cleaning
Before you start cleaning, gather the following materials:
- Toluene or Mineral Spirits: A solvent-based cleaning solution to dissolve and remove dried paint.
- Warm Water: For diluting the cleaning solution and rinsing the paint gun.
- Soft-Bristled Brush: For gently scrubbing and removing dried paint from small crevices.
- Microfiber Cloth: For wiping down the paint gun’s surface and removing excess cleaning solution.
- Air Compressor or Compressed Air: For blowing out the paint gun’s passages and removing trapped air.
- Gunslinger or Paint Gun Cleaning Tool: Optional tool for removing stubborn dried paint and cleaning hard-to-reach areas.

Step 1: Disassemble the Paint Gun
Disassemble the paint gun to access all parts that may have dried paint buildup. Remove the nozzle, needle, and any other components that can be taken out.
Step 2: Mix the Cleaning Solution
Mix 1 part toluene or mineral spirits with 2 parts warm water in a cup or bowl. The mixture should be approximately 20% solvent and 80% water.
Step 3: Soak the Paint Gun Parts
Submerge the disassembled paint gun parts in the cleaning solution and let them soak for 15-30 minutes. This will help loosen and dissolve the dried paint.
Step 4: Scrub the Paint Gun Parts
Use a soft-bristled brush to gently scrub each part, focusing on areas with heavy dried paint buildup. Be careful not to scratch or damage the paint gun’s surface.
Step 5: Rinse the Paint Gun Parts
Remove the paint gun parts from the cleaning solution and rinse them with warm water to remove any remaining cleaning solution and dried paint.
Step 6: Wipe Down the Paint Gun Parts
Use a microfiber cloth to wipe down each part, removing excess water and drying the surface.
Step 7: Blow Out the Paint Gun Passages
Use an air compressor or compressed air to blow out the paint gun’s passages, removing any trapped air and debris.
Step 8: Reassemble the Paint Gun
Reassemble the paint gun in the reverse order that it was disassembled.
Tips and Tricks for Cleaning a Paint Gun with Dried Paint
Here are some additional tips to help you clean your paint gun with dried paint:
- Use a Cleaning Solution with a Surfactant: Surfactant-based cleaning solutions can help emulsify and remove dried paint more effectively.
- Avoid Using Solvents with High Viscosity: Solvents like mineral spirits can be thick and difficult to work with. Opt for a solvent with a lower viscosity for easier cleaning.
- Don’t Use Abrasive Materials: Avoid using abrasive materials like steel wool or brushes with stiff bristles, as they can scratch the paint gun’s surface.
- Clean the Paint Gun Regularly: Prevent dried paint buildup by cleaning the paint gun after each use.
